Using the LOw Frequency ARray (LOFAR), European astronomers have carried out radio observations of a low-mass galaxy cluster known as PSZ2G145.92-12.53, dubbed the Ant Cluster. In result, they identified a radio halo—a ...
A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving 'normal' matter, ...

For several years, astronomers and cosmologists have theorized about the existence of an additional planet with a mass 10 times greater than that of Earth, situated in the outermost regions of the solar system. This hypothetical ...
The halo that surrounds our own Milky Way galaxy is much hotter than scientists once believed—and it may not be unique among galaxies.
