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.

Star clusters have been part of the Imaginarium of human civilization for millennia. The brightest star clusters to Earth, like the Pleiades, are readily visible to the naked eye. Astronomers have now revealed the existence of massive stellar halos, termed coronae, surrounding local star clusters.

Scientists propose a novel method for finding dark matter, the cosmos's mystery material that has eluded detection for decades. The proposed experiment, in which a billion millimeter-sized pendulums would act as dark matter sensors, would be the first to hunt for dark matter solely through its gravitational interaction with visible matter.

Using telescopes from around the world, astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon, known as a tidal disruption event, is the closest such flare recorded to date at just over 215 million light-years from Earth, and has been studied in unprecedented detail.

An international team of researchers has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in frequency of the lines in the solar spectrum which is produced when the light escapes from the gravitational field of the Sun on its way to Earth.

A team of gravitational-wave scientists reveals that when two black holes collide and merge, the remnant black hole 'chirps' not once, but multiple times, emitting gravitational waves - intense ripples in the fabric space and time - that inform us about its shape.
