Retro_Link Posted March 21, 2011 Share 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.

Because the space between each body is (incomprehensibly) massive. Two of them colliding would be (relatively) rare. Link to comment Share on other sites More sharing options...

Retro_Link Posted March 21, 2011 Share 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.

Dannyboy-the-Dane Posted March 22, 2011 Share 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. Link to comment Share on other sites More sharing options...

Retro_Link Posted March 27, 2011 Share 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.

Happenstance Posted August 4, 2011 Share 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 Link to comment Share on other sites More sharing options...

jayseven Posted August 7, 2011 Share 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! Link to comment Share on other sites More sharing options...
Emasher Posted August 8, 2011 Share 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 Share 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 Link to comment Share on other sites More sharing options...
Eenuh Posted August 15, 2011 Share 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.

Paj! Posted September 8, 2011 Share 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. :/ Link to comment Share on other sites More sharing options...
