But 'from dust we are,' so it's a very good thing. Better dusty than red n dead, as galaxies go.
And a bit of brown dust is what it takes to make blue stars! Better red than dead, they say, but when it comes to galaxies, red
is dead!
Speaking of galaxies, there is a pretty-looking one at about one o'clock, near a bit of blue fluff of nebulosity. I think that the galaxy is PGC 62700, which apparently also goes by the name of ESO 396-16.
All in all, this APOD is very much my cup of tea, of course. We've got an elongated filament of dust, exactly the kind of structure that is likely to produce stars, and the brightest stars it has given birth to are blue! And the entire skyscape is striking and varied with brand new young stars born out of dust, plus a magnificent ball of geriatric stars, plus a distant galaxy. And like Boomer said, the whole thing looks like a dog with a blue eye! The only thing that would have made it better is if it had looked like a cat.
