Gamma-ray beams seen in the Milky Way's central black hole suggest that the galaxy's center was much more active in the past, according to new research.

Harvard-Smithsonian Center for Astrophysics theorist Avi Loeb says that modern time is not the ideal scenario to study the universe, but rather about 13 billion years ago was.

Baby galaxies from the young Universe more than 12 billion years ago evolved faster than previously thought, shows new research from the Niels Bohr Institute.

For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second).

Researchers working at the University of Bonn in Germany have used computer simulations to discover the first evidence that the way in which stars form depends upon the conditions of their birth environments.
