Astronomers have identified the birth of a magnetar, a hyper-magnetized neutron star, by detecting a subtle warping of space-time predicted by Einstein’s general relativity. The discovery came from ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

Astronomers have identified the first clear evidence of a magnetar forming during a superluminous supernova, offering new insight into some of the brightest explosions in the universe.

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

Researchers at The University of Alabama in Huntsville have proposed a mathematical framework for a warp drive that operates without exotic matter, a requirement that has long made such concepts seem ...

General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...
