Giant elliptical galaxies are not as likely as disk-shaped galaxies, such as our own Milky Way, to be cradles of technological civilizations, according to a recent U.S. paper.
Scientists using the Hubble Space Telescope have detected quasars sending outbursts of energy roaring through their galaxies, according to new research.
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.
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.
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.
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.
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.
