In a galaxy, 600 million light-years away, a black hole deathmatch is ripping up spacetime, exposing some fascinating dynamics at the heart of a powerful quasar.
From round disks to oval clusters; many galaxies in the Universe have undergone a dramatic transformation over the past eight billion years or so.
Europe's XMM-Newton telescope took an X-ray scan of the Milky Way's core, capturing some dazzling high-energy delights.
Astronomers have discovered the smallest supermassive black hole lurking in the center of a dwarf galaxy around 340 million light-years away. Small it may be, but it could help to unlock some pretty hefty black hole mysteries.
A study of more than 200,000 galaxies shows that the universe is producing half as much energy as it did 2 billion years ago and continues to fade.
The most dense galaxies known to exist in our universe have been discovered by 2 undergraduate students while looking through years of archival data.
A newfound giant black hole nearly as massive as 7 billion suns is dozens of times larger than astronomers expected given its host galaxy's size, researchers say.
The prospect of measuring the mass of the most massive known objects in the universe would send most people into a cold sweat, but for astronomers it's all in a day's work.
