Analyzing data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers at Christ University in Bangalore, India, accidentally discovered a new ring-shaped galaxy, named DES…
The flares are roughly monthly due to the repeated stellar disruptions of a massive black hole
About 500 million light-years away, an unfortunate star the size of our sun is being sucked into a tiny black hole every week – and…
New cosmic constraints on the nature of dark matter
New research has revealed the distribution of dark matter in never-before-seen detail, at a scale of 30,000 light-years. The observed distribution fluctuations provide better constraints…
Astronomers detect the most distant galactic magnetic field ever seen
Astronomers have detected the magnetic field of a galaxy so distant that its light has taken more than 11 billion years to reach us—that is,…
Sterile neutrinos are one of the last loose ends in understanding the universe.
Neutrinos once again claim their share of prominence. And they do it for a good reason. Just two weeks ago we told you that CERN…
Astronomers discover a new class of cosmic explosion brighter than 100 billion suns
Astronomers have discovered a mysterious new type of cosmic explosion that dwarfs nearly all supernovae ever detected. Within 10 days, the peculiar explosion grew brighter…
Astronomers discover giant new galaxy at rest
Astronomers report the discovery of a new, massive, quiet galaxy with a high redshift. The galaxy, COSMOS-1047519, was discovered with the Keck I telescope. The…
