Galaxies are thought to form by the process of several smaller galaxies merging together. Now, scientists might be able to observe the process firsthand, after a recent discovery of seven groups of dwarf galaxies in the dark skies. The researchers used the largest optical survey of the night sky, as well as four different telescopes, to identify […]

Young stars shine a light into stellar evolution
Half of all stars that are similar to the Sun in the center of our solar system have at least one companion. There are two leading theories explaining why stars form in multiples, and a recent study provides further physical evidence to support one of those theories. The evidence comes in the form of high-resolution […]
Powerful aurora seen 18.5 light years away
Astronomers have detected auroral activity, seen on Earth as the Northern and Southern Lights, on a stellar object, believed to be a brown dwarf, outside of our Solar System. The team simultaneously detected radio and optical auroral emissions from the extrasolar body LSR J1853, located 5.67 parsecs or 18.5 light years away from our Sun. Additionally […]
Changing when stars were formed
A galaxy from the early universe is providing new insight on the formation of stars. Researchers have found one of the youngest and most remote galaxies, estimated to have formed when the Universe was approximately 700 million years old. The astronomers believe the galaxy has either been consistently forming stars at a moderate rate since […]
First of its kind star system spotted
While attempting to explain the odd shapes some planetary nebula researchers discovered the pair of stars that could be the first instance of two white dwarfs merging and exploding into a supernova. This finding supports the idea that double central stars may explain the odd shape of some nebulae. The researchers believe this is the […]
