This galaxy cluster has mysterious cosmic tendrils over 200,000 light-years long (image)
Astronomers have taken an unprecedentedly detailed look at the tendrils and filaments that wrap around supermassive black hole-dominated galaxies of Abell 2255.
Scientists spot high-speed galaxy collision 11 billion light-years away: 'We hence call this system the cosmic joust'
A galactic collision 11 billion light-years away reveals how an actively feeding supermassive black hole disrupts star formation in a nearby galaxy.
NASA diagnoses fracture in a 'huge cosmic bone' using X-ray observatory
A combination of X-ray from NASA's Chandra observatory and radio data indicates that a galactic "fracture" was likely caused by a special neutron star called a pulsar.

Galaxy cluster Abell 1489, as imaged by the International Gemini Observatory, contains more than 200 of the gravitationally-bound systems of stars, stellar remnants, interstellar gas and dust.
Our galactic neighbor Andromeda has a bunch of satellite galaxies — and they're weirdly pointing at us
The Andromeda galaxy's family of satellite galaxies point towards the Milky Way, and nobody knows why.
Vast swarms of hidden galaxies may be secretly bathing the universe in a soft glow
A fog of long-wavelength infrared light could be produced by dusty, star-forming galaxies that have remained hidden — until now, that is.
Incredible photo shows supermassive black hole blowing a jet of matter into interstellar space
A spiral galaxy known as NGC 4945 exhibits powerful winds of material blowing from the supermassive black hole located at its core in a new photo taken by the Very Large Telescope in Chile.
How do spiral galaxies get 'feathers'? All it takes is a little gravity
For over a century, astronomers have marveled at the beauty and complexity of spiral galaxies, which feature arms covered in a multitude of small-scale features known as feathers.
