Retro_Link Posted March 21, 2011 Posted March 21, 2011 It was like a laugh/amazing.That's the one! 1) a collision between two stars would occur approximately once every 3 x 10^17 years, or 3 x 10^7 times the age of the universe. 2) When (or if) Andromeda and the Milky Way collide, there is good chance that the solar system will be swept further from the galaxy core, or even out of the the galaxy all together. This would have no adverse effect on the solar system itself. 3)This shouldn't matter anyway, because in a billion years time the Sun will have warmed up enough to destroy all life on Earth, and Andromeda is set to collide with the Milky Way in about 4 billion years time. OK so... 1) I have no idea what this means! Your still saying sun collisions will take place, and what about all the planets/moons/meteorite of which there are far more of? 2) Yeah he did explain about suns/galaxies gettings thrown out the system. 3) Yeah I did kinda say I expected this would be the case.
MoogleViper Posted March 21, 2011 Posted March 21, 2011 1) I have no idea what this means!Your still saying sun collisions will take place, and what about all the planets/moons/meteorite of which there are far more of? Because the space between each body is (incomprehensibly) massive. Two of them colliding would be (relatively) rare.
Cube Posted March 21, 2011 Posted March 21, 2011 That's the one! OK so... 1) I have no idea what this means! Your still saying sun collisions will take place, and what about all the planets/moons/meteorite of which there are far more of? Planets would still be bound by the gravity of their star.
Retro_Link Posted March 21, 2011 Posted March 21, 2011 OK, but it wasn't just sun I was talking about, it was collisions between all objects up there... and the fact that any collisions are going to result in even more debris being flung about. I would have thought this knock-on would have had some effect. EDIT, yes but I assumed there would be overlap and changing of orbits, but I guess everythings happening too slowly and within too much space then.
Zell Posted March 21, 2011 Posted March 21, 2011 Because the space between each body is (incomprehensibly) massive. Two of them colliding would be (relatively) rare. Planets would still be bound by the gravity of their star. Pretty much this!
Dannyboy-the-Dane Posted March 22, 2011 Posted March 22, 2011 I smell Dunning-Kruger effect - the idea that most other people know what you do. It's the same reason I get bemused when people don't know the capital of, say, Turkey or Ukraine. Well, I wouldn't say I'm a terrible offender (I hope not, at least), especially since I actually really dislike it when people do it. It often comes with a heavy vibe of arrogance. That being said, it was most likely the case in this ... case.

Retro_Link Posted March 27, 2011 Posted March 27, 2011 (edited) I loved the Hubble image that peered into the farthest reaches of space and captured the most distant objects bathed in red light. Spooky! Edited March 27, 2011 by Retro_Link
Daft Posted March 27, 2011 Posted March 27, 2011 His last series was much better. Kind of disappointed.
Happenstance Posted August 4, 2011 Posted August 4, 2011 Apparently NASA scientists are claiming theyve found evidence of what could be flowing water on Mars. You can watch it live here http://www.bbc.co.uk/news/10318089
Grazza Posted August 7, 2011 Posted August 7, 2011 The Sky at Night tonight! Wonder if they'll fit in the news about the water?
jayseven Posted August 7, 2011 Posted August 7, 2011 ... No mention of it on news 24 - a google search produced this article/clip from 3 days ago. NASA to announce manned trip to mars in 2012? My money is on it!
Emasher Posted August 8, 2011 Posted August 8, 2011 NASA to announce manned trip to mars in 2012? My money is on it! I expect NASA's funding will be one of the first things to go when the Americans realize that they actually have to cut spending to decrease their deficit. So I wouldn't really count on it.
Retro_Link Posted August 15, 2011 Posted August 15, 2011 (edited) So a Meteor Shower started the other day... and continues for about another week I think... though getting less and less all the time. I think I saw one last night, though I can't be 100% as I stuck around for a couple of minutes afterwards, watching the same area of sky and didn't see another. But when there aren't clouds (which there are plenty of atm), it'll be well worth watching the skies. And from twitter... @Astro_Ron Ron Garan August 14, 2011 What a "Shooting Star" looks like #FromSpace Taken yesterday during Perseids Meteor Shower Thanks @JakeGaran 4 camera settings Edited August 15, 2011 by Retro_Link
Eenuh Posted August 15, 2011 Posted August 15, 2011 Yeah it's the Perseids meteor shower we're going through again. I think the peak was on August 11 and 12, but you couldn't see anything here because of the bright moon and the clouds heh. Not sure there's still many to spot now, but it's always worth a try.
Retro_Link Posted August 15, 2011 Posted August 15, 2011 Btw, the shooting star I though I saw was whilst looking some way East/SouthEast of The Plough.

Anything less just seems like a cop-out...
Paj! Posted September 8, 2011 Posted September 8, 2011 ^ I read about that the other week - Bjork posted it on Fbook (lel). Kinda cool. I wish discovery of planets were more of a *thing*. As in, people cared. :/
The Bard Posted September 8, 2011 Posted September 8, 2011 "Theoretical physicists in Great Britain are now conducting tests for the very first time to find evidence of multiple alternative universes, otherwise known as a multiverse -- http://www.digitaljournal.com/article/309875 " Oh god, I love the idea of an "anti-universe," reminds me of Time's Arrow, a Martin Amis book about a WW2 German vet in America living in reverse chronology.
Dog-amoto Posted September 14, 2011 Posted September 14, 2011 Cool. http://www.bbc.co.uk/news/science-environment-14915725
Serebii Posted September 23, 2011 Posted September 23, 2011 http://www.bbc.co.uk/news/science-environment-15017484 Posting this here as it could eventually lead to interstellar travel
Jimbob Posted September 23, 2011 Author Posted September 23, 2011 Interesting, read this earlier. Long way off yet, doubt we would see anything like this in our life-times.
