Astronomers using the Low-Frequency Array (LOFAR) telescope network have detected a vast ridge of radio emission connecting the merging galaxy clusters...
A spectacular new image from the NASA/ESA Hubble Space Telescope shows SPT-CL J0615-5746, a very massive group of galaxies located approximately 7.7 billion...
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.
This Hubble...
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...
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...
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...
Galaxy clusters are some of the most massive objects that can be found in the Universe. A new image from the NASA/ESA Hubble Space Telescope shows one...
Astronomers using the Atacama Large Millimetre/submillimetre Array (ALMA) have observed a supermassive black hole acting like a ‘monumental fountain’...
SDSS J0915+3826, a giant group of galaxies located approximately 4 billion light-years away, is so massive that its gravity bends light like a lens, making...
Astronomers using ESO’s Very Large Telescope have spotted a gigantic galaxy proto-supercluster in the early Universe, just 2.3 billion years after the...
