T O P I C R E V I E WmicropoozAs if global warming and NEO's weren't enough to worry about......there's this! Mother nature at her most violent: Caught on tape: Death star galaxy quote:The latest act of senseless violence caught on tape is cosmic in scope: A black hole in a "death star galaxy" blasting a neighboring galaxy with a deadly jet of radiation and energy.A fleet of space and ground telescopes have captured images of this cosmic violence, which people have never witnessed before, according to a new study released Monday by NASA."It's like a bully, a black-hole bully punching the nose of a passing galaxy," said astrophysicist Neil deGrasse Tyson, director of the Hayden Planetarium in New York, who wasn't involved in the research.But ultimately, this could be a deadly punch. GlintI've been seeing this galaxy, 321st in the 3rd Cambridge catalag (3C321), mentioned frequently lately in the mainstream and professional press (e.g. 'Death Star' Galaxy Black Hole Fires at Neighboring Galaxy). What they always fail to mention however is that this object is more commonly known as M82, a.k.a. "Cigar Galaxy", in Ursa Major -- a wonderful galaxy familiar to many. M82=NGC 3034=Arp 337=3C231 Lunar rock nutOh well, with gamma ray bursts from exploding supernovas and the fact that Andromeda M-31 and the Milky Way are possibly on a collision course, this just adds one more serving on the plate of galactic destruction, oh my.TerrySaturn VI have looked at M82 and M81 many many times and always thought that M82 was one galaxy albeit a starburst galaxy - it is a very "messy" looking galaxy to say the least. Are they now saying that it is actually 2 galaxies?? Maybe I have been out of the loop for too long.RichardGlint quote:Originally posted by Saturn V:Are they now saying that [M82] is actually 2 galaxies?? M82 is a member of the M82 group in which M81 and M82 are the dominant members. Kind of like how the Milky Way and the Andromeda Galaxy (M31) are the dominant members in our own "local group" of galaxies. M82 itself in turn apparently has one more dwarf galaxies associated with it, much like our own Milky Way has the Magellanic Clouds.Unfortunately the MSM either didn't care to mention or was too lazy to find out which of M82's dwarf members is getting blasted. But here's a link to a listing of members in the M81 group. Does anyone know if one of those galaxies is the same dwarf galaxy that's been implicated?
