European astronomers have observed a source on the sky known as Gaia20eae, which recently entered a phase of significant outbursting activity. Results of the new study suggest that this source may be an EXor-type eruptive ...
Physicists at MIT and elsewhere are blasting beams of ions at clouds of protons —like throwing nuclear darts at the speed of light—to map the structure of an atom's nucleus.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers from Japan have probed a nearby starburst galaxy known as NGC 1482. They detected a molecular gas outflow that could be essential to improving the ...
New results from precision particle detectors at the Relativistic Heavy Ion Collider (RHIC) offer a fresh glimpse of the particle interactions that take place in the cores of neutron stars and give nuclear physicists a new ...

Using NuSTAR spacecraft and the VERITAS array of telescopes, an international team of astronomers has investigated a gamma-ray binary known as HESS J0632+057. The study found that a compact object in this system is most likely ...
The center of our galaxy is a frenzy of activity. A behemoth black hole—4 million times as massive as the sun—blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and subsequently ...
