Image of the Day -The Brightest Object in the Observable Universe

At the center of this barred spiral galaxy lurks quasar QSO 1229+204 -- an object brighter than anything in the known universe. The distant quasar appears so bright that astronomers had to use the high resolving power of the Hubble Space Telescope (HST) just to observe the host galaxy that astronomers discovered is in the process of colliding with a dwarf galaxy, which possibly fuels a supermassive black hole causing QSO 1229+204 to shine so brightly. link
