A long streamer of hydrogen gas is being stripped from a spiral galaxy called D100 as it plunges toward the center of the Coma cluster (also known as Abell...
When the Universe was less than 1 billion years old, some of its stars turned into supermassive black holes. A key mystery in astronomy has been: why are...
SDSS J0928+2031, a huge group of galaxies in the constellation of Leo, is so massive that its strong gravity bends light like a giant lens.

The Large Magellanic Cloud, a dwarf galaxy located approximately 163,000 light-years away, is on a collision course with the Milky Way with which it will...
Supermassive black holes that lurk at the center of most galaxies are surrounded by coronas — mysterious features that are sources of highly energetic...
Dark matter is a mysterious substance that makes up about 85% of the matter in the Universe. It does not emit any kind of electromagnetic radiation and...
A new image from the NASA/ESA Hubble Space Telescope shows the core and the innermost parts of the spiral arms of a galaxy called Messier 100.
This Hubble...
The standard cosmological model known as LambdaCDM can only explain 5% of the observable Universe. The remaining 95% is famously made up almost entirely...
Astronomers believe that our Universe began forming the first stars when it was a few hundred million years old. Since then, the Universe has become a...
Globular clusters are ancient groups of hundreds of thousands or even millions of stars, gravitationally bound into a single structure about 100-200 light-years...
These threads of red snaking amidst dark, turbulent clouds make up a cosmic object known as SNR 0454-67.2. This tangled web is actually the remnants from...
Astronomers using data from NASA’s Chandra X-ray Observatory have determined that a massive group of galaxies called Abell 1033 is actually two galaxy...
WISE J224607.55-052634.9 (W2246-0526 for short), the most luminous galaxy ever discovered, is accreting (eating) at least three of its smaller neighbors,...
