Research published Tuesday by a Japanese astrophysicist says gamma rays may have been generated by the collision of dark ...

Physicists have discovered an exotic new state of matter that takes the form of a highly ordered crystal of subatomic particles. The new state of matter, called a "bosonic correlated insulator," could ...

In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, ...

Scientists at the world's largest atom smasher have discovered the longest-lived exotic-matter particle ever observed, and it has twice the charm of anything discovered to date. Physicists have yet to ...

This image combines visible light exposures of galaxy cluster Abell 2744 taken by the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope, with X-ray data from ...

Physicists have created a new way to observe details about the structure and composition of materials that improves upon previous methods. Conventional spectroscopy changes the frequency of light ...
