so, um, this is the gaia satellite currently in space. this is a model of it. yes, that's gaia.. it's one of the cornerstone missions of the european space agency. and, as you say, that's a model. the real one is ten times bigger. what have you been trying to find out using gaia? well, with gaia we're trying to discover the the shape of our galaxy and how it formed. and we need gaia's measurements to pinpoint exactly where the stars are and what the structure is. for example, how many spiral arms there are in our galaxy. it's crazy, isn't it, when you think about it. i grew up thinking that we knew that the milky way was a spiral with two arms. but what you're saying is, of course, we don't actually know because we're in it. we just think we know. exactly. so what kind of things is gaia measuring then? gaia is repeatedly scanning the sky and it's taking images at different times. and then, with these, by processing these images with a very complicated software system we can figure out how far away the stars are and how they move and with that we build up a map of the sky. it's b

everywhere aaron went he took gaia. that opened the door for him.other people, talking to staff, being more open. he had a softer, more nurturing side that emerged after gaia came into his life. aaron and i never had an overt conversation about the fact he killed his parents and now he was parenting a kitten. it was obvious to me though that whatever he couldn't feel for his own family and certainly the people he killed, he seemed to transfer all of these emotions over to this cat, which was interesting to observe, and we spent weeks there and i would check in with him periodically, and we were filming aaron looking at family photographs, and he started to pause and he seemed to almost be reminiscing in a good way as he looked at his mom, and he seemed to have a little kinder feelings towards her. >> this is probably the best picture i have ever seen of my mom. this was also in '85. this was when she graduated from a beauty school as a beautician. >> he was describing her in a kinder, more loving way than i had ever heard before. >> i mean, obviousl

what sort of things is gaia measuring?nd taking images at different times. by processing these images with a very competent at software system we can figure out how far away the stars are and how they move and with that we build up a map of the sky. it is basically like google maps for the galaxy. you have made some remarkable discoveries already, haven't you? yes. one thing we recently discovered is the milky way was involved in a head—on collision with another galaxy early in its lifetime, about 10 billion years ago. we see that the stars are on these and long dated kind of sausage shaped orbits that show they have come from another galaxy. for that reason, the galaxy that crashed into us is named the sausage galaxy. please thank georgia and anna. that was fascinating. and what show is complete without a cheeky selfie? if you were there, see if you can spot yourself here. three, two, one, here we go. soi so i have a background in technology and magic. and magicians are interesting. there are allusions accomplish what tec

so there are two members of congress, the gaia talked about from eastern kentucky. he was a lone voice for quite a long time. and then a congresswoman, mary ono whose son became hooked. and much later she came to this. and they came to some act named after a kid that became addicted and died. what the law would have done, would have required doctors that wanted to prescribing opioids, to have training and competence of training in treatment and addiction. one of the shocking things which you don't expect here but i heard from dr. to dr. that was in four years of medical training, about a day or two of training on pain. sexy doctors know very little about pain. we don't have many primary health care doctors here which is why there was such to the salesman because the salesman appeared to know more than they did and so they listened. so the push for this law and leading the fight against it was the american medical association to put this to convenience doctors. but aml had an industry relationship as well. they bought into the one that we mustn't deny people who need
