    Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away.

    Cartwheel Galaxy, ESO 350-40, is a lenticular galaxy about 500 mly away in the constellation Sculptor. It is an estimated 150,000 light-years across. The galaxy was once a normal spiral galaxy like the Milky Way before it apparently underwent a head-on collision with a smaller companion approximately 200 mya.

    The Flaming Star nebula lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga).

    Embers In The Dust


    Rho Ophiuchi is at the center of the blue nebula on the lower left. Antares, a red supergiant, lights up the yellow-red clouds. The distant globular cluster M4 is just upper left of center. Star clouds more colorful than humans can see, emitting light across the electromagnetic spectrum. Fine dust illuminated from the front by starlight appears blue. Gaseous clouds whose atoms are excited by ultraviolet starlight appear reddish. Backlit dust clouds block starlight and appear dark. (NASA APOD)

    #Astronomy: #Quasar: Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black

    Located approximately 7,000 light-years from Earth and nestled in the constellation Serpens lays the ultimate stellar nursery: the Eagle Nebula. This planetary nebula is home to seven strikingly beautiful pillars, most commonly referred to as the “Pillars of Creation," because it is in these towers that new stars are formed.
