[ Hubble Science: Multiwavelength Astronomy, The Big Picture ]

2
00:00:09,420 --> 00:00:16,740
Multiwavelength astronomy is basically looking at 
our universe with the full spectrum of light at  

3
00:00:16,740 --> 00:00:21,540
our disposal. So the light that we see with our 
eyes is the visible part of the electromagnetic  

4
00:00:21,540 --> 00:00:28,560
spectrum, but that spectrum extends dramatically 
much lower energy, longer wavelengths out into  

5
00:00:28,560 --> 00:00:34,980
the radio microwave and radio. And then higher 
energy the ultraviolet, the X-ray, the gamma rays,  

6
00:00:34,980 --> 00:00:40,620
this is an entire sweep of the electromagnetic 
spectrum and our eyes are only sensitive to the  

7
00:00:40,620 --> 00:00:46,980
visible. And our atmosphere here on Earth actually 
protects us from many many wavelengths of light,  

8
00:00:46,980 --> 00:00:52,200
ultraviolet light and high energy light is very 
damaging to life, it also blocks much of the  

9
00:00:52,200 --> 00:00:58,980
infrared part of the spectrum. Hubble is above the 
Earth's atmosphere, we're in a low earth orbit and  

10
00:00:58,980 --> 00:01:04,920
so we are above much of the atmosphere and so we 
are free to observe in the ultraviolet and the  

11
00:01:04,920 --> 00:01:11,460
near-infrared. So we have ultraviolet instruments 
and filters on there that expand our vision  

12
00:01:11,460 --> 00:01:16,980
greatly in the ultraviolet and very uniquely 
from space, and we also have instruments that go  

13
00:01:16,980 --> 00:01:22,620
into the near-infrared now so that stretches our 
vision in the other direction into the infrared.  

14
00:01:22,620 --> 00:01:27,960
And getting into space has been so 
powerful for us when we get up above  

15
00:01:27,960 --> 00:01:32,340
the atmosphere and we're able to look at those 
same objects now that we saw invisible before,  

16
00:01:32,340 --> 00:01:37,680
but add that ultraviolet part of the picture, 
the infrared part of the picture we're now taking  

17
00:01:37,680 --> 00:01:42,300
our vision of a very narrow part of the object 
and we're widening it to get the big picture.

18
00:01:42,300 --> 00:01:46,419
[ Shot of colorful Lagoon Nebula in visible light, a line moves from left to right changing the view. It's still the Lagoon Nebula, but now in infrared. More muted, but we can peer through the gas and see previously hidden stars. ]

19
00:01:46,419 --> 00:01:50,760
[ Shot of the Pillars of Creation, slowly tilting up as the colorful blues and greens of the visible transform into the infrared view. Once again seeing previously hidden stars. ]

20
00:01:50,760 --> 00:01:56,700
So for example when we look in our own solar 
system, when we look at the ultraviolet at  

21
00:01:56,700 --> 00:02:01,620
a planet like Jupiter, the ultraviolet 
actually revealed that there was motion  

22
00:02:01,620 --> 00:02:06,900
happening in the polar region of Jupiter 
very similar to the Aurora on the Earth.

23
00:02:06,900 --> 00:02:09,960
[ Very blue image of Jupiter's pole with flashing lights on top, these are the aurora. ]

24
00:02:09,960 --> 00:02:13,680
That gave us a piece of the picture 
of our solar system, of Jupiter,  

25
00:02:13,680 --> 00:02:16,800
and of the sun's interaction with the 
planets in our own solar system that  

26
00:02:16,800 --> 00:02:20,640
we could not have seen without that 
ultraviolet view of the solar system.

27
00:02:20,640 --> 00:02:23,640
[ Full visible view of Jupiter with blue aurora at its North Pole. ]

28
00:02:23,640 --> 00:02:30,900
Mystic Mountain is a beautiful multi-color image 
of a star-forming region, or a stellar nursery.  

29
00:02:30,900 --> 00:02:35,400
What we see in the visible from Mystic 
Mountain is how the light from these  

30
00:02:35,400 --> 00:02:40,440
newly-born stars is engaging with the material 
around it, the gas and the dust that's still  

31
00:02:40,440 --> 00:02:45,600
there that has yet to form stars. We look 
at Mystic Mountain not in the visible now  

32
00:02:45,600 --> 00:02:51,180
but in the infrared we're actually able to 
peer through a lot of that gas and dust.

33
00:02:51,180 --> 00:02:53,918
[ Shot of Mystic Mountain in the infrared as it slowly dissolves into the bright colors of the visible view. ]

34
00:02:53,918 --> 00:02:58,620
Multiwavelength view looking at Mystic 
Mountain in both the visible and the  

35
00:02:58,620 --> 00:03:06,420
infrared lets us see that picture of star birth, 
early star formation in a much more nuanced and  

36
00:03:06,420 --> 00:03:11,520
detailed way than either just the infrared 
or the visible alone would allow us to do.

37
00:03:11,520 --> 00:03:17,520
[ One again we see Mystic Mountain, this time in the visible, the image slowly rotates to the right as it begins to dissolve into the infrared view. Revealing once hidden stars ]

38
00:03:17,520 --> 00:03:22,260
So multiwavelength astronomy has allowed us 
to take objects that we've been observing for  

39
00:03:22,260 --> 00:03:27,240
hundreds of years and put that new color on them 
to understand them better as objects, how they  

40
00:03:27,240 --> 00:03:34,920
evolve, the dynamics that's going on on there. 
Galaxies, stars, nebulae, supernova remnants, and  

41
00:03:34,920 --> 00:03:40,620
now James Webb Space Telescope it's going to add a 
tremendous amount of infrared information to that  

42
00:03:40,620 --> 00:03:46,320
multiwavelength picture, it's going to lead the 
way in that area of the electromagnetic spectrum  

43
00:03:46,320 --> 00:03:51,180
and it's going to continue this multiwavelength 
investigation of our universe for decades to come.
