00:00:00.000 --> 00:00:05.002
There is so much going on inside this 
seemingly tiny galaxy.

2
00:00:05.002 --> 00:00:07.699
Nicknamed the Firefly Sparkle for appearing

3
00:00:07.699 --> 00:00:10.920
like a swarm of lightning bugs on a warm summer night,  

4
00:00:10.920 --> 00:00:13.934
this galaxy is gleaming with star clusters.

5
00:00:13.934 --> 00:00:17.280
Due to its long warped arc, researchers easily

6
00:00:17.280 --> 00:00:19.869
picked out 10 distinct star clusters,

7
00:00:19.869 --> 00:00:22.621
each of which have been examined in great detail.

8
00:00:22.621 --> 00:00:25.790
They appear here in shades of pink, purple, and blue.

9
00:00:25.790 --> 00:00:28.480
The color of each helped scientists to confirm

10
00:00:28.480 --> 00:00:32.113
that star formation didn’t happen all at once in this galaxy,

11
00:00:32.113 --> 00:00:34.240
but was staggered through time.

12
00:00:34.240 --> 00:00:37.211
Using NASA's James Webb Space Telescope,

13
00:00:37.211 --> 00:00:40.520
this is the very first time researchers have detected and  

14
00:00:40.520 --> 00:00:43.089
examined a galaxy that existed around

15
00:00:43.089 --> 00:00:45.560
600 million years after the big bang.

16
00:00:45.560 --> 00:00:48.780
which carries many resemblances to our own Milky Way

17
00:00:48.780 --> 00:00:51.720
at a similar stage of its own development.

18
00:00:51.720 --> 00:00:55.051
Researchers can’t predict how this disorganized 
galaxy 

19
00:00:55.051 --> 00:00:57.240
will take shape over billions of years, 

20
00:00:57.240 --> 00:00:59.804
but there are two other galaxies “hanging 
out”

21
00:00:59.804 --> 00:01:01.680
within a tight perimeter that may

22
00:01:01.680 --> 00:01:04.858
influence how it builds mass as it evolves.

23
00:01:04.858 --> 00:01:07.360
Each time one galaxy passes another,

24
00:01:07.360 --> 00:01:10.316
gas condenses and cools, allowing new stars to
 

25
00:01:10.316 --> 00:01:13.600
form in clumps, adding to the galaxies’ masses.

26
00:01:13.600 --> 00:01:18.320
Previously scientists were unsure if it 
would be possible to resolve a galaxy  

27
00:01:18.320 --> 00:01:22.860
that existed so early in the universe into so 
many distinct components,

28
00:01:22.860 --> 00:01:26.801
but Webb was able to image the galaxy well for two reasons:

29
00:01:26.801 --> 00:01:29.200
The first is a benefit of the cosmos:  

30
00:01:29.200 --> 00:01:32.053
A massive foreground galaxy cluster radically

31
00:01:32.053 --> 00:01:34.680
enhanced and magnified the distant galaxy’s

32
00:01:34.680 --> 00:01:38.884
appearance through a natural effect known 
as gravitational lensing.

33
00:01:38.884 --> 00:01:41.824
When combined with the telescope’s specialization 

34
00:01:41.824 --> 00:01:44.120

in high-resolution infrared light,  

35
00:01:44.120 --> 00:01:52.538
Webb delivered unprecedented new 
data about the galaxy’s contents.
