How the Universe Works (2010–…): Season 7, Episode 4 - The Interstellar Mysteries - full transcript

Discoveries about interstellar space, the space between the universe's stars, reveal that it's not empty and unremarkable as previously thought, but filled with weird objects and strange ...

100:00:04,134 --> 00:00:08,806
Space between interstellar space is interstellar
2
00:00:10,566 --> 00:00:17,847
The interstellar space is vast
The most unknown and unplanned
3
00:00:18,795 --> 00:00:22,956
Astronomers are now exploring this great abyss
4
00:00:23,963 --> 00:00:28,222
They discover amazing things
5
00:00:30,869 --> 00:00:35,092
Space between interstellar is busy and busy
6
00:00:35,127 --> 00:00:39,655
There are stray planets that are not connected to a star
7
00:00:39,690 --> 00:00:43,271
Cosmic rays, and interstellar gas withdrawal
8
00:00:43,306 --> 00:00:47,833
They have super-speed stars out there
9
00:00:47,868 --> 00:00:51,009
There are the greatest secrets in our universe
10
00:00:51,044 --> 00:00:53,179
Interstellar space is where we originated
11
00:00:53,179 --> 00:00:57,221
All are among the stars

"Interstellar Mysteries"
15th
00:01:16,123 --> 00:01:21,551
We live in a small solar system
On the outskirts of the Milky Way galaxy
16
00:01:24,156 --> 00:01:31,512
Eight planets and more than one hundred and eighty
All around the sun
17
00:01:31,547 --> 00:01:35,830
In our solar system, the sun is the city's mayor
18
00:01:35,865 --> 00:01:40,174
Do what the sun wants us to do
19
00:01:40,209 --> 00:01:46,077
The effect of the sun extends to more
Of light year in each direction
20
00:01:47,203 --> 00:01:50,612
Limits the limits of our solar system
21
00:01:50,647 --> 00:01:56,546
Somewhere there ends the effect
The sun and other stars begin
22
00:01:56,581 --> 00:01:59,690
This is the interstellar space input
23
00:02:04,567 --> 00:02:10,685
Interstellar space is the region
Between the star systems in our galaxy
24
00:02:12,832 --> 00:02:17,092
So far we know little about them
25
00:02:17,127 --> 00:02:21,121
We thought for a long time that space
Interstellar is completely empty
26
00:02:21,156 --> 00:02:23,839
But it turned out to be a mistake
27
00:02:23,874 --> 00:02:28,828
Many things have happened there
It is at the forefront of astronomy
28
00:02:28,863 --> 00:02:35,076
One of the biggest signs of space
Between the stars came on our doorstep
29
00:02:41,435 --> 00:02:44,895
, October 2017
30
00:02:44,930 --> 00:02:49,955
The Pan Starz-1 telescope has detected something unusual
31
00:02:49,990 --> 00:02:54,845
"Pan Stars" is an observatory in "Hawaii"
Wiping wide sections of the sky
32
00:02:54,880 --> 00:02:57,368
Looking for things changing
33
00:02:59,709 --> 00:03:05,301
Suddenly, a visitor came up and roared through the solar system
34
00:03:05,336 --> 00:03:08,615
It was going at a speed of two hundred thousand miles per hour
35
00:03:08,650 --> 00:03:14,011
It was faster than we expected
For a body in a solar system
36
00:03:14,046 --> 00:03:20,274
His path indicated that his orbit was not restricted to the sun
37
00:03:20,309 --> 00:03:29,887
It was not like any lane or any path
Or any other orbit in our solar system
38
00:03:29,922 --> 00:03:33,891
Astronomers reached an astounding conclusion
39
00:03:36,138 --> 00:03:41,853
It turned out that he was not a body of
The solar system travels from a distance
40
00:03:41,888 --> 00:03:45,082
But something came from another star
41
00:03:45,117 --> 00:03:49,755
I think everyone was amazed by that
42
00:03:53,735 --> 00:04:00,470
Our visitor is between the first star
Known passes through our solar system
43
00:04:00,505 --> 00:04:04,756
It is the first object we ever discover
44
00:04:04,791 --> 00:04:07,884
He grew up outside the solar system
45
00:04:07,884 --> 00:04:14,477
All that we have seen, every sinner and all
An asteroid has arisen within our solar system
46
00:04:14,512 --> 00:04:23,945
Giant giant body enters our system
The sun, something I see only in dreams
47
00:04:23,980 --> 00:04:26,905
But I never thought it would be true
48
00:04:29,565 --> 00:04:38,143
"Scientists launched it" Omwa-mua
Bahawian messenger from afar arrives first
49
00:04:39,174 --> 00:04:46,845
This object came from interstellar space to
Our Solar System The main question is what is it?
50
00:04:50,570 --> 00:04:54,272
The shape of the body was puzzling
51
00:04:55,304 --> 00:05:00,595
It was shaped like a cigar, the longest of its width
52
00:05:00,630 --> 00:05:07,792
This is exceptional, there is no body in our system
We measured it daily and it was so long
53
00:05:09,552 --> 00:05:12,768
"Amwa-mua" seemed abnormal
54
00:05:12,803 --> 00:05:16,748
It has been filled with the imagination of scientists
55
00:05:16,783 --> 00:05:24,957
What we should remember about scientists is that we are still
Human beings, we read science fiction and our fantasies
56
00:05:26,218 --> 00:05:29,043
I admit that when I first heard about him
"Once my thought went to" Rama
57
00:05:29,078 --> 00:05:32,217
"From the story of Arthur C, Clarke" An appointment with Rama
58
00:05:32,252 --> 00:05:37,231
It was a long space ship that came from another star
59
00:05:38,334 --> 00:05:44,149
He reminded me of some of our designs for interstellar spaceships
60
00:05:44,184 --> 00:05:52,500
Which must exceed its width
To reduce interstellar gas friction
61
00:05:52,535 --> 00:05:58,484
"Could be" Amwa-mua
Spacecraft between stellar?
62
00:06:02,224 --> 00:06:08,401
Astronomers including Prof, "Avi
"They took the idea seriously
63
00:06:08,436 --> 00:06:13,178
We decided to follow this body
Using the best approaches in the world
64
00:06:13,213 --> 00:06:17,549
We monitor any radio transmissions from it
65
00:06:18,482 --> 00:06:23,435
Astronomers searched for signs of any space contact
66
00:06:27,356 --> 00:06:34,215
But after eight hours of listening
Over many frequencies we have received nothing
67
00:06:34,250 --> 00:06:42,294
Unfortunately, we did not monitor any submissions
A natural body, I bet all my money on it
68
00:06:42,329 --> 00:06:49,152
I was disappointed, I was more eager if
We found evidence of space civilization
69
00:06:52,038 --> 00:06:55,343
There are no small green men this time
70
00:06:55,378 --> 00:06:58,629
Amwa-Mua "natural body"
71
00:06:58,664 --> 00:07:01,821
But what exactly?
72
00:07:01,856 --> 00:07:05,683
Observers first thought he might be guilty
73
00:07:05,718 --> 00:07:08,680
A snowy body with a few rocks
74
00:07:08,715 --> 00:07:14,834
These objects exist
Away from the star and easy to extrude
75
00:07:15,938 --> 00:07:20,880
But the culprit transgresses this
Proximity to the sun will warm
76
00:07:20,915 --> 00:07:25,928
To turn the snow into a gas to be a toxic effect
77
00:07:26,911 --> 00:07:31,535
On "Amwa-mua" did not see
Astronomers have done this
78
00:07:31,570 --> 00:07:38,489
There was no mist around him as we expected
It is guilty when the snow turns into gas
Games
00:07:38,524 --> 00:07:46,257
It was mysterious and I think everyone watching it is an asteroid
80
00:07:47,095 --> 00:07:50,638
When the team tracked "Amwa-mua" across the sky
81
00:07:51,767 --> 00:07:54,583
There was an unexpected paradox
82
00:07:55,481 --> 00:08:01,077
When "Amwa-mua" crossed our solar system
It was basically falling into the sun
83
00:08:01,077 --> 00:08:07,923
Accelerates strongly after crossing the sun before it
It emerges from the solar system from the opposite direction
84
00:08:07,958 --> 00:08:12,765
But something strange happened when he walked away
The sun did not slow down as we expected
85
00:08:12,800 --> 00:08:16,419
It did not slow down fast enough
86
00:08:16,454 --> 00:08:20,753
Amoa-mua took a boost through our solar system
87
00:08:20,788 --> 00:08:22,731
but how?
88
00:08:22,732 --> 00:08:26,191
We think the reason is the gas drop
89
00:08:26,226 --> 00:08:32,996
In the sense that it was issued a little of
The gas was working as a rocket propulsion engine
90
00:08:33,031 --> 00:08:38,138
It is like a weak jet engine on the surface
Give him a little bit of payment over time
91
00:08:38,173 --> 00:08:44,700
This weak payment reveals
The true "Amwa-Mua" identity
92
00:08:45,572 --> 00:08:48,567
In that case he tends to be more guilty
93
00:08:48,602 --> 00:08:53,019
His gas emission was not enough to see him
94
00:08:56,766 --> 00:09:03,146
By pushing the gas out, this traveler
Interstellar may travel from star to star
95
00:09:03,181 --> 00:09:08,859
But knowing the place of his arrival
In the galaxy more difficult
96
00:09:09,817 --> 00:09:15,543
Knowing that "Amwa-Mua" is gassing
It changes its speed and changes its path
97
00:09:15,578 --> 00:09:18,307
It is difficult for us to do so
98
00:09:19,180 --> 00:09:22,673
Amwa-mua may be safe now to get away quickly
99
00:09:22,708 --> 00:09:29,065
But faces the solar system
Bombardment from another source between stellar
100
00:09:29,100 --> 00:09:33,601
It travels towards the Earth near the speed of light
101
00:09:33,636 --> 00:09:42,152
Cosmic rays are shots
The universe engulfs interstellar space
102
00:10:01,766 --> 00:10:07,770
The surface of "Amwa-mua" tells us a story
His journey through interstellar space
103
00:10:08,680 --> 00:10:13,083
The interesting thing about
Amwa-mua "is his color, it's red"
104
00:10:13,118 --> 00:10:17,571
"I stand on a surface the same as the surface" Amwa-mua
105
00:10:17,606 --> 00:10:22,387
When you look around you see a cover
Bright of dark color for all rocks
106
00:10:22,422 --> 00:10:26,585
The highest valley extends to the mountains from behind
107
00:10:29,060 --> 00:10:35,939
"Scientists believe that the brightness of" Amwa-mua
The red comes from organic molecules that fall on it
108
00:10:35,974 --> 00:10:38,314
Which represent the building units of life
109
00:10:39,213 --> 00:10:47,181
What a wonderful thing that comes from different origins and passes
In our neighborhood and owns some organic matter
110
00:10:47,181 --> 00:10:50,954
Gold mine may be ours
111
00:10:52,787 --> 00:11:00,503
In our solar system, distant objects
Comets and asteroids also carry loads
112
00:11:01,353 --> 00:11:09,491
This happens because their surfaces are cut by cosmic rays
This changes the nature of chemicals on the surface
113
00:11:09,526 --> 00:11:11,919
"We think the same thing happened to" Amwa-mua
114
00:11:11,954 --> 00:11:17,511
There was an interstellar space
And the cosmic rays were buried over the ages
115
00:11:20,276 --> 00:11:26,754
Cosmic cosmic rays are particles
High energy makes its way across the universe
116
00:11:30,260 --> 00:11:36,981
Space is filled between interstellar
Of the cosmic rays
117
00:11:37,016 --> 00:11:45,291
Particles such as protons, electrons and possibly some
The heaviest and most unusual particles blowing through the universe
118
00:11:45,326 --> 00:11:49,463
Some cosmic rays can
It travels up to 99% of the speed of light
119
00:11:49,498 --> 00:11:52,279
Active high speed particles
120
00:11:54,328 --> 00:11:59,860
It takes a lot of energy
To speed up anything near the speed of light
121
00:12:00,722 --> 00:12:08,145
Cosmic rays come from sources
Many active, strong and violent in our universe
122
00:12:09,019 --> 00:12:14,745
Anything with a huge explosion generates cosmic rays
123
00:12:15,667 --> 00:12:25,044
One of the most powerful cosmic ray generators
Is the death of a huge star
124
00:12:30,237 --> 00:12:33,597
The supernova is a high-activity explosion
125
00:12:33,632 --> 00:12:38,170
So active that he can
Create all exciting particles
126
00:12:39,116 --> 00:12:43,362
When the star's fuel runs out, it collapses
127
00:12:43,397 --> 00:12:48,992
The star's mass collapses inside to produce a huge explosion
128
00:12:53,988 --> 00:12:57,848
The shock wave hits the surrounding gas
129
00:12:57,883 --> 00:13:01,099
Magnifying magnetic fields
130
00:13:01,134 --> 00:13:05,591
The particles are trapped there and confined
Magnetic fields of this gas
131
00:13:05,626 --> 00:13:08,868
Bounce back and forth strongly
132
00:13:08,903 --> 00:13:13,406
,,, is accelerating so
133
00:13:13,441 --> 00:13:20,214
In the end, the particles move quickly
And the magnetic field can not restrain it
134
00:13:22,216 --> 00:13:25,846
And it is launched at a speed approaching the speed of light
135
00:13:28,466 --> 00:13:31,330
The cosmic rays have a mass
136
00:13:31,365 --> 00:13:34,838
And it is destroyed
137
00:13:34,873 --> 00:13:40,643
Cosmic rays are the shots of the universe
138
00:13:40,678 --> 00:13:43,433
The space is interstellar
139
00:13:43,468 --> 00:13:46,759
But we are protected
140
00:13:50,025 --> 00:13:56,347
Cosmic rays of space between
Starry is battling with another superpower
141
00:13:57,927 --> 00:14:02,246
Our guard in the solar system
142
00:14:03,629 --> 00:14:08,570
We may think that the sun is the source of energy
And the warmth of the earth, giving life only
143
00:14:08,605 --> 00:14:12,683
But they also protect us in ways that they do not know
144
00:14:13,667 --> 00:14:19,590
The sun produces a stream of particles
Charged solar wind
145
00:14:20,439 --> 00:14:26,595
Particles run through the planets
At a speed of about one million miles per hour
146
00:14:29,116 --> 00:14:33,159
But in the end it loses its power
147
00:14:33,194 --> 00:14:37,012
There is a region where solar wind slows down
148
00:14:37,012 --> 00:14:42,108
Make its way in that interstellar substance
And eventually slows down and stops
149
00:14:45,684 --> 00:14:50,000
Solar wind carries the magnetic field of the sun
150
00:14:50,000 --> 00:14:53,598
To be a bubble around our solar system
151
00:14:54,446 --> 00:14:59,375
We call it the "solar envelope" and symbolizes
For this giant magnetic field of the sun
152
00:14:59,410 --> 00:15:04,121
It basically works as a protective layer to protect us
Of those cosmic rays
153
00:15:04,156 --> 00:15:10,115
If it does not exist, levels will increase
Radiation that hits the ground
154
00:15:10,150 --> 00:15:15,967
So the sun really protects us from
The dangerous environment of interstellar space
155
00:15:17,305 --> 00:15:21,657
Protect the solar envelope from most cosmic rays
156
00:15:21,692 --> 00:15:26,010
But some succeed in gaining access to the solar system
157
00:15:26,045 --> 00:15:32,046
Fortunately, the Earth also has its own defense mechanism
158
00:15:32,081 --> 00:15:38,252
We have our magnetic field which works on
Deflection of low-energy cosmic rays
159
00:15:38,287 --> 00:15:43,658
We have a thick protective cover from the atmosphere
160
00:15:43,693 --> 00:15:47,527
Which absorbs most high-energy cosmic rays
161
00:15:47,562 --> 00:15:52,084
Before they had the opportunity
To reach us here on the roof
162
00:15:57,491 --> 00:16:03,905
Cosmic rays can travel from interstellar space
That changes DNA and causes diseases
163
00:16:03,940 --> 00:16:08,054
But without it, perhaps we have never been here
164
00:16:08,089 --> 00:16:12,381
Even a fraction of cosmic rays
Which passes through our atmosphere to the Earth's surface
165
00:16:12,416 --> 00:16:15,972
May have a profound impact on the evolution of life
166
00:16:16,966 --> 00:16:23,259
Cosmic rays can destroy acid
Nuclear device that carries life information
167
00:16:24,157 --> 00:16:29,190
These particles break down and change
The atoms collide with cosmic rays
168
00:16:29,225 --> 00:16:35,239
, And mobile information changes ,, This is a boom
That's what natural selection is about
169
00:16:35,274 --> 00:16:42,116
So we humans are strongly bound to life
In interstellar space around us
170
00:16:44,931 --> 00:16:50,475
But space is interstellar
Also larger objects
171
00:16:50,510 --> 00:16:56,057
Objects that can completely erase life
172
00:17:16,090 --> 00:17:23,299
Our solar system circulates around a center
Milky Way at 143 mph
173
00:17:24,124 --> 00:17:31,305
In the middle of the sun, one
Two hundred billion stars in our galaxy
174
00:17:31,340 --> 00:17:39,664
We do not live in an isolated bubble alone in the galaxy
Here, we live in a cluster of other nearby stars
175
00:17:42,188 --> 00:17:47,816
The movement of those stars has effects
Long term on our solar system
176
00:17:50,512 --> 00:17:54,805
, behind the planets and our solar shell
177
00:17:58,531 --> 00:18:01,915
The Ort cloud is located
178
00:18:01,950 --> 00:18:06,150
On the edge of real interstellar space
179
00:18:06,185 --> 00:18:11,253
Ort cloud is the remnant of the composition of the solar system
180
00:18:11,288 --> 00:18:16,701
Small dirty snowy bodies, mean comets
181
00:18:19,915 --> 00:18:23,527
The comets in the Ort cloud are very far away
182
00:18:23,562 --> 00:18:26,960
So that they hardly adhere to the sun
183
00:18:26,995 --> 00:18:34,035
She spends most of her time looking around
The sun is sober in its cold depths
184
00:18:34,070 --> 00:18:38,135
But it is occasionally shaken
185
00:18:39,614 --> 00:18:43,546
Our sun moves through interstellar space
186
00:18:43,581 --> 00:18:45,962
As well as other stars
187
00:18:46,943 --> 00:18:51,518
Our sun revolves around the galaxy and corresponds
Its neighbors are inevitably stars
188
00:18:51,553 --> 00:18:57,244
Sometimes one passes through or near the Ort cloud
189
00:18:58,045 --> 00:19:03,517
The attraction of the next star may shake the Ort cloud
190
00:19:06,805 --> 00:19:11,464
Sends rain from comets
It travels through the solar system
191
00:19:14,570 --> 00:19:18,148
Some may collide with the ground
192
00:19:32,295 --> 00:19:36,554
Comets that fall into the system
The solar interior must pay attention to it
193
00:19:36,589 --> 00:19:38,654
You may be serious about life here on Earth
194
00:19:38,689 --> 00:19:41,466
One of the things we do is look at the galaxy
195
00:19:41,501 --> 00:19:46,248
We monitor which star may be approaching
Any time in the near future
196
00:19:48,551 --> 00:19:51,647
"With the new Space Observatory named" Gaia
197
00:19:51,682 --> 00:19:57,154
Astronomers watch millions of nearby stars in our galaxy
198
00:19:58,634 --> 00:20:03,220
They track their movement through interstellar space
199
00:20:03,255 --> 00:20:05,620
What is the next star that will cross Earth?
200
00:20:05,655 --> 00:20:07,207
It turned out we knew
201
00:20:07,242 --> 00:20:11,359
"There is an orange dwarf called the Glyce-710
202
00:20:12,694 --> 00:20:21,711
In 2018, new data showed that
Gliese-710 "in a collision course with Ort cloud"
203
00:20:21,746 --> 00:20:24,874
It will throw some dirt and some dust
204
00:20:24,909 --> 00:20:32,350
It may carry bad news for the solar system
To get unwanted visitors
205
00:20:36,451 --> 00:20:43,173
"We were lucky to have" Gliese-710
Will not arrive 1,3 million years ago
206
00:20:44,909 --> 00:20:49,472
But there are other stars there
207
00:20:49,472 --> 00:20:53,282
There are all those stars that you see
In our skies in the Milky Way disk
208
00:20:53,375 --> 00:20:59,133
And tend to move in the same direction
At a hundred miles per second around the middle
209
00:21:00,605 --> 00:21:04,272
Gaia discovers stars that follow different rules
210
00:21:06,286 --> 00:21:09,490
They do not seem to move with the galaxy movement
211
00:21:09,525 --> 00:21:12,645
In turn they race through space
212
00:21:14,368 --> 00:21:21,151
They are quickly launched as artillery shells and move three
Or four or five times other stars in the galaxy
213
00:21:21,186 --> 00:21:24,706
It seems to be moving away from the center
214
00:21:26,198 --> 00:21:31,770
Those cosmic shells know
Also named super-speed stars
215
00:21:34,100 --> 00:21:38,213
What makes it go so fast?
216
00:21:38,248 --> 00:21:44,995
Some of these stars originate from star systems
Two of its members burst into a greater crisis
217
00:21:45,030 --> 00:21:56,498
Removes the attractive association of the other star to allow him to escape
Or being thrown across the galaxy in its high-speed orbit
218
00:21:58,658 --> 00:22:03,391
I have some super stars
The past speed is darker
219
00:22:03,426 --> 00:22:07,221
It drips from a black hole
220
00:22:07,256 --> 00:22:11,735
There are trillions of black holes in the universe
221
00:22:11,770 --> 00:22:19,066
There are almost huge black holes in the center
All large galaxies including our galaxy
222
00:22:20,475 --> 00:22:25,657
These monsters create
Chaos on the associated stars
223
00:22:25,692 --> 00:22:31,179
There is a binary star system and two orbits
Around the black hole in the middle of our galaxy
224
00:22:31,214 --> 00:22:37,623
When they approach, one falls into the hole
Black and the other shoots away at high speed
225
00:22:40,319 --> 00:22:45,380
Those super stars glow
Speed through interstellar space
226
00:22:45,415 --> 00:22:51,178
Its starry winds bring beauty from chaos
227
00:22:52,004 --> 00:22:59,553
Most of the high-speed stars we see are
Giant stars are bigger, warmer and brighter than the sun
228
00:22:59,588 --> 00:23:02,973
They make their way through interstellar matter
229
00:23:03,008 --> 00:23:07,003
Its winds extend and hit with gas and dust
230
00:23:07,038 --> 00:23:14,880
What you see when you look at it is that
The bow is as beautiful as the front wave of the ship
231
00:23:14,915 --> 00:23:21,881
We have pictures of them, they are beautiful beautiful patterns
232
00:23:24,489 --> 00:23:29,987
High-speed stars draw the universe's plate
233
00:23:32,341 --> 00:23:39,817
It may sound quiet, but space between
The star is far from calm
234
00:23:45,387 --> 00:23:48,839
It is not a property, it is a wild area
235
00:23:48,874 --> 00:23:50,939
You can do whatever you wish
236
00:23:50,974 --> 00:23:57,706
In rugged galactic areas, the bad guys prevail
237
00:24:15,692 --> 00:24:18,689
Dozens of light years away from the sun
238
00:24:18,724 --> 00:24:22,310
Mysterious bodies disappear in the dark
239
00:24:23,168 --> 00:24:26,322
We saw only part of the material there
240
00:24:26,357 --> 00:24:29,721
This is the next big discovery
241
00:24:31,056 --> 00:24:39,662
In 2016, scientists monitored a weak source of light
Infrared light 59 light years away from Earth
242
00:24:44,492 --> 00:24:49,251
He is darker than a star and does not revolve around a star
243
00:24:51,556 --> 00:24:55,175
It is only a stray planet
244
00:24:55,210 --> 00:24:58,852
When we think of the planet
We believe that an object revolves around a star
245
00:24:58,887 --> 00:25:02,019
In fact, this is the current definition of the planet
246
00:25:02,054 --> 00:25:04,519
What if it is not about anything?
247
00:25:04,554 --> 00:25:07,190
We call it planets
248
00:25:13,161 --> 00:25:18,029
The next year he picked up
Astronomers have more detailed images
249
00:25:18,928 --> 00:25:22,277
They found not one world but two worlds
250
00:25:24,320 --> 00:25:32,659
This is amazing, that body is the middle of space, if not two
The stars of the two planets are orbiting each other
251
00:25:34,174 --> 00:25:37,716
The constellation is four times the mass of Jupiter
252
00:25:37,751 --> 00:25:40,276
300 million miles from each other
253
00:25:40,311 --> 00:25:43,748
More than three times
The distance between the earth and the sun
254
00:25:43,783 --> 00:25:47,325
They revolve around each other every century
255
00:25:48,235 --> 00:25:52,167
Do not imagine a planet
Charda but two planets
256
00:25:52,202 --> 00:25:54,727
Two planets revolve around each other
257
00:25:55,663 --> 00:26:00,360
They may be two giant giants as the buyer
If they were, there would be no surface
258
00:26:00,395 --> 00:26:04,281
But if they were old, it was lost
They have enough time to cool down
259
00:26:04,316 --> 00:26:06,270
They may have two surfaces
260
00:26:06,305 --> 00:26:11,658
, We do not know, but they will be gloomy
There is no nearby star to illuminate them
261
00:26:14,498 --> 00:26:21,538
The stagnant planets slide into eternal darkness
Across the wide, cold expanse of interstellar space
262
00:26:23,187 --> 00:26:27,522
Not touched by light for millions of years
263
00:26:28,370 --> 00:26:32,243
Suppose you found yourself standing up
On the surface of one of those stray planets
264
00:26:32,278 --> 00:26:36,088
It will be a strange sight, there will be no sun
265
00:26:36,123 --> 00:26:40,019
It will only be the night sky around you
266
00:26:40,955 --> 00:26:45,190
Imagine a dark night
Lunar is here on Earth
267
00:26:45,225 --> 00:26:49,279
This is the level of light that exists
In interstellar space
268
00:26:51,634 --> 00:26:57,692
Physicists believe there are billions
Planetary planets in our galaxy
269
00:26:57,727 --> 00:27:00,762
Planet for all four stars
270
00:27:01,830 --> 00:27:05,798
The question is why you exist
Those stray planets?
271
00:27:05,833 --> 00:27:11,006
Have you been alone or have been prostrated?
Somehow outside its solar system?
272
00:27:11,041 --> 00:27:13,348
The answer holds both
273
00:27:19,022 --> 00:27:25,369
Some of the stray planets were formed
Groups of gas that did not become stars
274
00:27:25,404 --> 00:27:32,481
Others formed as planets around
Stars in solar systems as our system

When the systems were formed
Solar, were violent places

Sometimes the planets crash
And become one body

Sometimes you miss the whole thing
They stray away from each other and toss

So these planets exist
Her entire life is completely lonely

Without a star warming it, the planets look
Uncertainty places unbearable life

The planet stalks alone in
Space will not be good for life

It's cold there, if it's a size
Earth may be a frozen ball

But in 2018, astronomers announced that life
May harbor a moon around a stray planet

There are moons orbiting Jupiter
Saturn is so dense with planetary gravity

It has nothing to do with the sun



When those satellites deviate
By the gravity of the planet

The friction generates heat that makes the water liquid

It is possible if the planet can
Stray from keeping his moons

It was probably a satellite
Contains liquid ocean under its surface

You do not need a star
But the planet is heating up

Space between the stars is not empty

But it is full of unrelated objects that have no habitat

You may imagine space between
Asteroid as a pinball machine

There are high-speed stars and rare planets

There are even moons from their planets

They all go out there

Interstellar space is more active
And life than we would imagine as illustrated

He even has a pull sing

Hundreds of light years away, quantities drift
A vast gas and dust across interstellar space



Imagine all this space between
The stars are full of gas and dust

Full of star formation stories
Planets, we were missing a lot

Scientists call gas and dust
Interstellar interstellar medium

It is most of the material present in the galaxy

They are atoms of hydrogen and little
Of helium atoms here and there

The interstellar medium does not spread evenly across the galaxy

It is cobbled and lumpy and there are areas of it
More materials and other materials less

Areas with more materials
The drag is called interstellar

What is the cloud between stellar only
Intensive concentration of gas and possibly dust

Scattered across our galaxy

The interstellar clouds may spread
For vast distances across the universe

Some up to one million times the mass of the sun

This amazes me

When I look at that interstellar clouds
I realize that its size is light years

The interstellar clouds are more than
Just pools of gas and dust

It is alive

We know that places where the stars are made up

They are also places of star death

Stars are formed when
The interstellar cloud collapses

Gravity pulls materials together to ignite pulp

But astronomers are not fully aware of the process

Understand the shape and composition of the cloud
It is important to understand the star formation process

Some shapes and structures are not as big
Enough in some dimensions to allow the collapse of the cloud

All we know about it depends on its shape

So figuring out the shape is the key to understanding the process

But there is a problem

When we look at the universe we are
We see things on the sky

So we may look at the installation as the sweep between
And have little information about its depth

One of the biggest challenges for astronomers is
Disassemble the three-dimensional shape of that drag

In 2018, there was a big shift for scientists
In their efforts to understand star formation

490 light-years from Earth

"There is an interstellar cloud called Mosca

Similar to a fine snake

This dark painting is dark
The expression looks like a dark two-dimensional cloud

Its a silhouette off
The stars are in the background in the sky

Astronomers have examined Mosca with infrared light

They found out that she was singing

It oscillates, creating moving waves
Across that cloud back and forth

Dynamic fluid waves are called
Magnetism which looks fantastic

The team converted the waves to
"Musical tones for the song" Moska

It turns out that when you study so you can
Determine the 3D shape of that cloud

Through the movement of waves across it

It's like listening to
The sound frequency of the machine you do not see

And trying to reshape the nature of that machine

The low tone tells you that
Tapping for a huge machine like a cello

While the high tone
It represents a smaller machine like Kalkman

Just as different machines produce different sounds

The drag structures
Different hesitate in different ways

She will sing completely different songs

Voices, whether to say or frequencies issued
Of the cloud is a fundamental guide to its shape and composition

Although the Mosca cloud looks like a line in the sky
three hundred fifty
00:35:23,376 --> 00:35:26,190
Astronomers were able to determine their stereotypical shape

Not just a thread but a disk
As if we see a disc standing on its own

Mosca "is more like a pie than a snake"

Inn did look at the pie from the side

This is amazing, as if we were wearing glasses
Stereoscopic for the first time and see the depth of the universe

The same technology can be used
To study the interstellar clouds

Bring with it a lot of knowledge treasures
About the structures and processes taking place there

We discover that interstellar space
In our galaxy is full of substances

But the total number is minus

It turns out that if we took all the materials
Which we now see around the universe

And we collected it would not equal quantity
The total that we know is there

One-third of the materials are missing

Where is it then?

To find them, we should look
Behind interstellar space

To the dark side
Mysterious space between the Hungarian

Milky Way is one trillion
Galaxies in the Universe Perspective

The Milky Way is a disk
About 100,000 light-years away

It is full of stars and lots
Of planets, gas and dust

But where does our galaxy end?

Where do the other galaxies begin?

Installation as our shop has no break point

They become less dense and gradually fade away
Whenever we move into space between the Hungarian

, galaxies have huge gaps

Space between Hungarian

But as the space between
The asteroid is not empty

New research shows that it holds a great puzzle answer

We know the amount of normal material
Emerging from the Big Bang

We can look around today and count
All the regular items we see

The problem is that they are not equal

There are speeches by galaxies in our universe

Not huge enough

About a third of the ordinary matter in the universe is missing

There is an ordinary substance that is not connected to galaxies

Where is it then?

Assume a theory about the place of those
Ordinary Lost Article

They float out of our galaxy in hot gas

Scientists believe that this hot gas
May exist in long filaments between galaxies

But the gas is thin and too widespread to detect

Until now

In 2018, astronomers studied a star
The distant matte pseudo is called 1 AS 1553

The false star exists when the black hole feeds

It releases light and we can see it across the universe

The stars are false
Four billion years until you reach us

But observing the observers is something strange

Something absorbs light
It passes through the universe

Accused ,, hidden threads of gas
Suspended in intergalactic space

These results assume that part
A great matter of ordinary matter in our universe

Not confined to galaxies

Do not live within the city limits

But live in long flows
Thin connecting galaxies together

, by heating its shock waves to millions of degrees

Those threads of gas may extend across the universe

The article is interpreted
She was missing all that time

This opens an interesting question

Whether it is there
And failed to accumulate in the galaxies?

Or have they started inside the galaxies and pushed out?

We do not know explicitly

Space between interstellar

, and now the inter-Hungarian space

More life than we thought
410
00:41:42,293 --> 00:41:44,866
, of the stray planets

, to pull the singer gas

Space between the stars stranger than
Imagination, but we are now beginning to cut his story

Because there is so much
We are ignorant of interstellar space

Making it more important to explore
Try and find out what is there

Exists in space between
The stars are more than we know

This is the beauty of exploration

The beauty of knowledge is expanding
Always presented there always

Who knows what might be there too
And what may be hidden in the darkness between the stars
