"These two supernova remnants are helping us to better understand the dynamics of our home galaxy’s neighborhood," ...

The Milky Way can be seen as something of a bully, having devoured many smaller galaxies to achieve its vast mass, and ...

Astronomers looked more closely at one of seven stars that looked like possible Dyson sphere candidates from earlier observations.

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

Rapid X-ray oscillations detected near the innermost orbit of a supermassive black hole could indicate the presence of a nearby orbiter such as a white dwarf ...

The Dwarf 3 is great for astrophotography beginners, but it also has lots of useful tools for more experienced hobbyists.

Astronomers are trying to understand a mysterious cosmic explosion that the Einstein Probe spacecraft spotted in April last year.

An LSU-led team would like to use a high-flying Antarctic balloon-borne infrared telescope to detect the chemical makeup of ...

Using data from the European Space Agency’s Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is ...

By combining data from NASA’s IRAS and NuSTAR telescopes, scientists have uncovered more hidden supermassive black holes than earlier estimates suggested. Their findings indicate that over a third of ...

After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.
