Title:
Spiral Galaxy NGC 2997 from VLT
Explanation:
NGC 2997 is a grand design spiral galaxy [ http://www.seds.org…]. Its small nucleus and sprawling spiral arms give it a type Sc [ http://zebu.uoregon…] designation. NGC 2997, pictured above [ http://www.eso.org/…], is speeding away [ http://archive.ncsa…] from us at about 1100 kilometers per second, which would place it at about 55 million light years [ http://chandra.harv…] distant, given current estimates of the expansion rate [ http://csep1.phy.or…] of our universe. NGC 2997 [ http://www.ast.cam.…] is thought to have a mass of about 100 billion times that of our Sun [ http://antwrp.gsfc.…], but is probably less massive than our own Milky Way galaxy [ http://casswww.ucsd…]. NGC 2997 is not seen face-on [ http://antwrp.gsfc.…] - it is thought tilted by about 45 degrees. NGC 2997 is particularly notable [ http://adsbit.harva…] for a nucleus [ http://antwrp.gsfc.…] surrounded by a chain of hot giant clouds of ionized [ http://csep10.phys.…] hydrogen [ http://pearl1.lanl.…].
