The universe is some 13 billion years old and is often imagined as just a vast expanse of dark, almost empty space getting colder with time. Yet new research shows that all of its clusters of galaxies are simultaneously getting hotter as they get older.

An international team of astronomers has identified the farthest example of a rare class of gamma-ray emitting galaxies. The so-called BL Lacertae object was discovered at cosmic dawn, within the first two billion years of the age of the universe.

New research suggests that an early model of dark energy presents a competing theory to explain the accelerating expansion of the Universe that offers all the benefits of current models without the baggage that comes associated with the cosmological constant.

Nearly 3 billion years ago, a dwarf galaxy plunged into the center of the Milky Way and was ripped apart by the gravitational forces of the collision. Astrophysicists announced today that the merger produced a series of telltale shell-like formations of stars in the vicinity of the Virgo constellation, the first such 'shell structures' to be found in the Milky Way.

Astronomers have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars. This heated halo, called the circumgalactic medium, was the incubator for the Milky Way's formation some 10 billion years ago and could be where basic matter unaccounted for since the birth of the universe may reside.
