1 00:00:00,010 --> 00:00:04,040 [female reporter] The world's most recognizable telescope, the Hubble Space Telescope is turning 2 00:00:04,040 --> 00:00:09,060 25. Here to show us some of Hubble's most beautiful images an talk about some of the 3 00:00:09,060 --> 00:00:13,090 science, Hubble helped to discover, is Dr. Mark Clampin, from NASA's Goddard Space Flight 4 00:00:13,090 --> 00:00:15,110 center. Thanks for joining us. 5 00:00:15,110 --> 00:00:16,140 [Dr. Clampin] Hello. 6 00:00:16,140 --> 00:00:21,150 [female reporter] So, Hubble Space Telescope is turing 25, can you show us some of Hubble's 7 00:00:21,150 --> 00:00:23,220 most beautiful images? 8 00:00:23,220 --> 00:00:28,260 [Dr. Clampin] Sure, so I think every images Hubble takes is breath taking in its own way. 9 00:00:28,260 --> 00:00:34,300 this picture here you are about to see, is a picture of Jupiter and this one is particularly special 10 00:00:34,300 --> 00:00:40,320 because you see three of it's moons crossing in front of it. This is the Eagle Nebula 11 00:00:40,320 --> 00:00:46,370 which is a big dust cloud and this is the Cat's Eye Nebula or planetary nebula. 12 00:00:46,370 --> 00:00:53,490 Here we see two galaxies superposed on each other and then this is a image of the 13 00:00:53,490 --> 00:00:59,520 Hubble Deep Field showing distant galaxies in the universe then finally this is a very active 14 00:00:59,520 --> 00:01:01,570 galaxy called M82. 15 00:01:01,570 --> 00:01:04,610 [female reporter] What are some of the surprising things you've learned? 16 00:01:04,610 --> 00:01:08,670 [Dr. Clampin] Well we've learned a lot of really interesting things with Hubble and have rewritten 17 00:01:08,670 --> 00:01:15,690 the astronomy and astrophysics text books. One example is that the expanding universe is 18 00:01:15,690 --> 00:01:22,720 actually accelerating due to the unseen effect of dark energy. We've been able to images galaxies 19 00:01:22,720 --> 00:01:29,780 in the deep field back to a billion years after the big bang. Closer to home for instance in our own 20 00:01:29,780 --> 00:01:34,810 solar system we've been able to find that Pluto has five moons. 21 00:01:34,810 --> 00:01:40,860 [female reporter] Just yesterday you released a new image, can you talk about that? 22 00:01:40,860 --> 00:01:46,900 [Dr. Clampin] So the new image is called "Westerlend 2" and its a cluster of young stars 23 00:01:46,900 --> 00:01:54,940 Basically it's another region of intense star formation with lots of young stars being born 24 00:01:54,940 --> 00:02:02,020 and you can see sort of dust and gas to the lower left there and a cluster of stars to the top right. 25 00:02:02,020 --> 00:02:04,040 Very beautiful image. 26 00:02:04,040 --> 00:02:09,120 [female reporter] Hubble is also a human story, Astronauts service the telescope five times. 27 00:02:09,120 --> 00:02:12,190 Can you talk about some of the obsticales Hubble has overcome? 28 00:02:12,190 --> 00:02:19,220 [Dr. Clampin] Exactly, so everytime we service Hubble it's basically going to work in space 29 00:02:19,220 --> 00:02:25,260 and on some of the early missions, we were basically just replacing whole instruments. 30 00:02:25,260 --> 00:02:30,270 and the astronauts were able to overcome that challenge. On later servicing missions they 31 00:02:30,270 --> 00:02:35,340 actually had to service instruments in the bay and take panels off and put in individual circuits 32 00:02:35,340 --> 00:02:40,350 boards, which is much, much harder. So the challenges have gotten more and more 33 00:02:40,350 --> 00:02:43,390 and the astronauts have always met them. 34 00:02:43,390 --> 00:02:45,420 [female reporter] How has Hubble touched people? 35 00:02:45,420 --> 00:02:50,440 [Dr. Clampin] So, Hubble has touched our culture in a very big way. You see Hubble images 36 00:02:50,440 --> 00:02:55,480 every where, on stamps. You go into bookstores you see it on book covers 37 00:02:55,480 --> 00:03:01,530 you see Hubble images in museums. You often see them without realizing in TV shows 38 00:03:01,530 --> 00:03:08,610 and movies. But I think more importantly it's also got a generation of kids very interested in science 39 00:03:08,610 --> 00:03:14,650 at an early age and that's very important, get them interested in doing careers later on 40 00:03:14,650 --> 00:03:15,680 in science and engineering. 41 00:03:15,680 --> 00:03:19,720 [female reporter] In 2018, NASA will launch the James Webb Telescope 42 00:03:19,720 --> 00:03:21,750 tell us a little about this mission. 43 00:03:21,750 --> 00:03:25,790 [Dr. Clampin] So Webb is the successor to the Hubble Space Telescope. 44 00:03:25,790 --> 00:03:32,890 It's basically is an infrared telescope, so Hubble sees visible light, like we do with our eyes. 45 00:03:32,890 --> 00:03:39,950 The James Webb Telescope will work in the infrareds and it will be able to peer into regions 46 00:03:39,950 --> 00:03:44,050 like the Eagle Nebula here where we know there is a nursery of stars being born. 47 00:03:44,050 --> 00:03:49,090 We will be able to peer into the dust and actually study the stars as they are being born. 48 00:03:49,090 --> 00:03:52,150 Understand how planets form around those stars in that process. 49 00:03:52,150 --> 00:03:54,230 [female reporter] Finally, where can we find out more? 50 00:03:54,230 --> 00:03:59,290 [Dr. Clampin] So you can find more about Hubble images at nasa.gov/hubble 51 00:03:59,290 --> 00:04:02.376 [female reporter] Great! Thanks for joining us.
