Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein’s theory of General Relativity in the extremely strong gravity of a pair of ...

A new analysis of gravitational-wave data reports statistical evidence consistent with a long-predicted gap in black hole masses, a range where stellar physics is expected to make black holes from ...

New stellar detection: NASA’s Roman Space Telescope will use gravitational microlensing to spot isolated neutron stars and ...

Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as "ONe novae" as a ...
