The new observations show a mega-structure being assembled in a system called Abell 1758, located about three billion light-years from Earth. It contains two pairs of colliding galaxy clusters that are heading toward one another.
When we look far into the distant universe - we expect to find distant giant radio galaxies comparatively small. But to our surprise the new research found that these giants still appear enormous even though they are so far away.
Astronomers have spotted three supermassive black holes (SMBHs) at the center of three colliding galaxies a billion light years away from Earth. That alone is unusual, but the three black holes are also glowing in x-ray emissions.
An international team of astronomers led by the University of Tokyo used ALMA to view 39 previously-undiscovered ancient galaxies, a find that could have major implications for astronomy and cosmology.
Researchers have clarified one of the mysteries of 2018 in the field of extragalactic astrophysics: the supposed existence of a galaxy without dark matter. New results show that the galaxy is "normal" with dark matter present.
This 360-movie offers an unparalleled opportunity to look around the center of the galaxy, from the vantage point of the central supermassive black hole, in any direction the user chooses.
Using ESA's Gaia spacecraft and NASA’s Hubble Space Telescope, astronomers have come up with the most accurate measurement yet of the Milky Way’s total mass. It contains about 1.5 trillion times the mass of Earth’s Sun.
Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies. This particular image was taken using the Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope.
A release of data gathered by the Low Frequency Array (LOFAR) telescope network in Europe has discovered more than 300,000 potential galaxies in a tiny corner of the northern sky.
A duo of astronomers has spotted three new globular clusters in the Milky Way’s bulge, a 10,000-light-year-wide central structure made primarily of old stars, gas and dust.
