![]() One of the things I find interesting in that general direction of these stars is the Fornax Void. It's a whole bunch of nothing. And I mean a major amount of nothing. The universe on the biggest scale is like a bubble bath where the surface of the bubbles is clusters of clusters of galaxies. In Fornax we see a huge area where stuff mostly isn't. Back to the stuff that is. The Fornax Dwarf galaxy is a community of mostly elderly stars that orbit the Milky Way at a safe distance. Some dwarf galaxies are being cannibalized by our own galaxy because in space the big ones eat the little ones. For instance, the Fornax galaxy itself appears to be munching on a few globular clusters. Some day the Milky Way might get around to swallowing the Fornax galaxy, perhaps after we run out of the snacks within easier reach. ![]() ![]() Galaxies eat everything they can but it's not always good for them. A lot of middle-aged galaxies have cores that are unusually bright as though the supermassive blackholes in their centers have been swallowing stars in unhealthy quantities. It's not as bad as quasars though, which are when younger galaxies are pigging out like some county fair eating contest. Seyferts aren't that bad but it's still pretty gross. ![]() Carpe Noctem Skywise Unlimited |
