1 00:00:01,541 --> 00:00:04,910 As Hubble reaches the grand old age of 27, 2 00:00:04,920 --> 00:00:07,200 the Hubblecast team have a lot to celebrate. 3 00:00:07,700 --> 00:00:10,000 For the past 10 years we’ve been capturing 4 00:00:10,000 --> 00:00:14,000 the science, culture, successes and trials of Hubble 5 00:00:14,000 --> 00:00:18,000 and we reflect on the highs — and lows — of the Hubblecast in this, 6 00:00:19,400 --> 00:00:22,000 our 100th episode! 7 00:00:24,400 --> 00:00:26,500 Hello and welcome to the Hubblecast. 8 00:00:27,000 --> 00:00:29,600 Now we all know that Hubble is an amazing telescope, 9 00:00:29,800 --> 00:00:33,000 amazing enough to fill 100 episodes, 10 00:00:33,000 --> 00:00:36,000 that’s about 10 hours worth of the Hubblecast. 11 00:00:36,500 --> 00:00:38,500 So what’s changed over time? 12 00:00:38,500 --> 00:00:40,500 What are some of the best, funniest, 13 00:00:40,500 --> 00:00:43,000 or just weirdest episodes that we’ve made? 14 00:00:43,000 --> 00:00:46,500 That’s exactly the question, that we, the Hubblecast team, 15 00:00:46,500 --> 00:00:48,600 have been asking ourselves, and so, 16 00:00:48,600 --> 00:00:51,800 let’s take a look at our, Hubblecast highlights. 17 00:00:53,000 --> 00:00:58,900 Remember these? In episodes 50, 78 and 79, 18 00:00:58,900 --> 00:01:02,000 we answered your questions about Hubble and astronomy, 19 00:01:02,000 --> 00:01:05,000 which were fantastic! And here’s my favourite bit. 20 00:01:11,500 --> 00:01:14,000 [The answer is, everywhere! 21 00:01:14,000 --> 00:01:16,000 Now the key is to realise, 22 00:01:16,000 --> 00:01:19,800 that the term Big Bang does not describe an event in space, 23 00:01:19,800 --> 00:01:21,700 but rather, one in time. 24 00:01:21,800 --> 00:01:25,500 The Big Bang was not an explosion it was an event, 25 00:01:25,500 --> 00:01:27,900 that happened everywhere at the same time, 26 00:01:27,900 --> 00:01:31,900 and the Universe was infinitely large right from the start, 27 00:01:31,900 --> 00:01:35,000 and so there is no single point from which the Universe is expanding, 28 00:01:35,000 --> 00:01:37,900 and also, there is no centre. 29 00:01:37,900 --> 00:01:42,500 It is simply impossible to define a centre in an infinitely large space.] 30 00:01:43,300 --> 00:01:45,000 We had good fun with these episodes, 31 00:01:45,000 --> 00:01:48,000 and what they showed us, was that you were really interested 32 00:01:48,000 --> 00:01:52,900 in the challenging physics concepts that lie at the core of Hubble science, 33 00:01:52,900 --> 00:01:56,100 and we’ve gone to some lengths to try and explain these. 34 00:01:58,300 --> 00:02:00,500 We’ve used diagrams… 35 00:02:01,000 --> 00:02:06,000 […it bends the space around it and acts like a gigantic magnifying glass.] 36 00:02:09,000 --> 00:02:12,000 [... what our 3D Universe expands into… ] 37 00:02:12,000 --> 00:02:13,500 We’ve used balloons… 38 00:02:14,000 --> 00:02:16,000 [... is just as meaningless.] 39 00:02:18,500 --> 00:02:20,000 [Let’s say goodbye to Hubble’s pretty pictures... ] 40 00:02:20,000 --> 00:02:24,000 And we even used... unicorns? 41 00:02:26,000 --> 00:02:27,500 [Rainbows?] 42 00:02:28,800 --> 00:02:31,000 And, for the sake of the Hubblecast, 43 00:02:31,000 --> 00:02:34,400 we even disregard our own personal safety, 44 00:02:34,400 --> 00:02:37,500 like the time I got blown up by a supernova 45 00:02:38,000 --> 00:02:39,500 ...several times. 46 00:02:41,700 --> 00:02:44,000 Even after 10 years, we’re not bored, 47 00:02:44,000 --> 00:02:46,900 because Hubble gives us so much to work with. 48 00:02:46,900 --> 00:02:51,500 We’ve explored its history, celebrated its birthdays, 49 00:02:51,500 --> 00:02:54,000 and followed its last servicing mission. 50 00:02:54,000 --> 00:02:55,000 But most of all, 51 00:02:55,000 --> 00:02:58,000 we’ve been delving into Hubble’s most amazing discoveries, 52 00:02:58,000 --> 00:03:00,900 and finding new ways to share them with you. 53 00:03:02,900 --> 00:03:06,000 We covered supernovae, black holes, 54 00:03:06,000 --> 00:03:15,000 distant galaxies, exoplanets, ah, and quasars. 55 00:03:21,600 --> 00:03:26,600 [Now when matter falls into a black hole it forms this big swirling disc 56 00:03:26,600 --> 00:03:30,000 which heats up and gives off a lot of powerful radiation. 57 00:03:30,000 --> 00:03:32,000 The more matter falls into the black hole, 58 00:03:32,000 --> 00:03:34,000 the more powerful the radiation. 59 00:03:34,500 --> 00:03:38,700 Now these active accreting black holes are called quasars 60 00:03:38,700 --> 00:03:40,500 and they’re amongst the most luminous 61 00:03:40,500 --> 00:03:43,200 and most powerful objects in the Universe.] 62 00:03:44,900 --> 00:03:47,000 What we’re trying to do at the Hubblecast, 63 00:03:47,000 --> 00:03:50,400 is to bring the scientific insights that Hubble has afforded to us, 64 00:03:50,400 --> 00:03:54,500 their implications, but also their fun and beauty, to everyone. 65 00:03:55,000 --> 00:03:59,000 And there’s plenty of beauty to be found, just look at this. 66 00:03:59,800 --> 00:04:02,000 Now at the Hubblecast, we’ve been very lucky 67 00:04:02,000 --> 00:04:05,000 to have an incredibly talented team over the years. 68 00:04:05,000 --> 00:04:09,000 A team of writers, directors, producers, cameramen, 69 00:04:09,000 --> 00:04:11,500 illustrators, and visual artists. 70 00:04:11,500 --> 00:04:14,000 It is only with their help, 71 00:04:14,000 --> 00:04:18,000 that we all get to enjoy Hubble’s data in all of it’s glory 72 00:04:18,000 --> 00:04:21,000 and travel to places like the Pillars of Creation. 73 00:04:31,000 --> 00:04:32,500 They also illustrate for us, 74 00:04:32,500 --> 00:04:35,000 those things that have to be left to the imagination. 75 00:04:35,700 --> 00:04:38,500 All to the next generation of telescopes. 76 00:04:39,900 --> 00:04:43,000 Now those were our favourite Hubblecast moments, 77 00:04:43,000 --> 00:04:44,000 but what are yours? 78 00:04:44,000 --> 00:04:48,000 Tell us on Facebook or Twitter. 79 00:04:49,000 --> 00:04:50,300 This is Dr J, 80 00:04:50,300 --> 00:04:52,000 signing off for the Hubblecast.
