I don't know much about space exploration or the nature of the solar systems for that matter, but this is really interesting stuff. story here
I was reading this earlier. I think the best part about it was that we didn't even know about the Sagittarius Galaxy until 1994.....great stuff. D
And Astrophysicist DrMacman now? Current theory of galactic composition has a black hole (massive blackhole) at the center of each - so if the two collided, a significant number of stars and such would have been *eaten* by both blackholes and they probably merged to form one big one...... D
hmm...it's almost past the point of comprehension to imagine these things... and yeah...it's nuts that it's less than 10 years that we've known about Sagittarius...
well, it wasn't until we could look at the sky in infrared that it was visible. Pretty cool stuff...they also mention that small galaxies like this are what built up the bigger ones to begin with. And that there 's evidence (strands of stars and such) that show that many have been gobbled up in the distant past.... D
