"Godzilla" galaxy hosts a trillion suns

The largest spiral galaxy in the local universe UGC 2885, is 2.5 times wider than the Milky way and hosts a trillion stars, 10 times more than Earth’s galactic home. UGC 2885 is located some 232 million light years away in the constellation Perseus.

A Galaxy That Formed Less than a Billion Years After the BB

Astronomers have spotted an unusually distant star-forming galaxy, the light of which took a whopping 13 billion years to reach Earth. Perhaps most incredibly, however, the galaxy was observed directly, without gravitational lensing.

Three supermassive black holes in galactic merging

Extensive observations indicated the presence of three supermassive back holes in the three galaxies NGC 6240 that are  the process of merging. Up until now, such a concentration of supermassive black holes had never been discovered in the universe.

Something is syncing the movements of galaxies

Scientists have been gathering a growing well of evidence that our universe may be connected via a vast array of large-scale "structures" that seem to reach out across the cosmos to synchronize the movements of galaxies that are separated by vast distances.

Chandra spots a mega-cluster of galaxies in the making

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.

Giant radio galaxies defies conventional wisdom

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.

Caught in the act: galaxies turning into quasars

Astronomers have identified six previously mild-mannered galaxies that suddenly transformed into voracious quasars, erupting in feeding frenzies powered by supermassive black holes.

Three Supermassive Black Holes Orbiting Around Each Other

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. 

Astronomers Uncover Dozens of Previously Unknown Galaxies

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.

The mystery of the galaxy with no dark matter

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.

Hubble's One Picture Containing 265,000 Galaxies

Hubble’s latest contribution comes in the form of a deep-sky mosaic image that was constructed using 16 years’ worth of observations. Known as the “Hubble Legacy Field“ it contains roughly 265,000 galaxies.

Unusual galaxies defy dark matter theory

Researchers from Yale University claim to have found stronger evidence to confirm that galaxies with little or no dark matter do really exist.

New Visualization Provides Ultra HD View of Our Galaxy Center

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.

Milky Way tips the scales at 1.5 trillion solar masses

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.

Hubble's dazzling display of two colliding galaxies

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.
