A cosmic explosion detected on July 4, 2025, began with a 0.4-second gamma-ray burst and then continued glowing in softer ...

Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst ...

An international team of astronomers, including researchers from the Department of Physics and the Hong Kong Institute for ...

On July 4, 2025, astronomers watched a cosmic explosion do something it was not supposed to do. The event began with a ...

Einstein Probe avoids that delay by monitoring a wide area of the sky at soft X-ray energies. On July 4, 2025, the ...

A neutron star collision produced an unusual nine-minute X-ray glow, possibly powered by a newborn magnetar that kept releasing energy after the blast.

For decades, astronomers have identified collisions between two neutron stars through bursts of gamma rays that can disappear in less than two seconds. But some of these violent encounters may also ...

It's commonly believed that there's no sound in space, but that's far from the case. For instance, sonifications from NASA have allowed us to hear the sounds of a black hole, and, in 2025, astronomers ...

At 8:56 AM ET on Tuesday, NASA's Fermi Gamma-ray Space Telescope automatically detected a new long-duration gamma-ray burst, designated GRB 260623A, during the sudden collapse of what is likely a star ...

The 2026 Nobel Prize in Physics has been awarded to Francis Halzen “for decisive contributions to the IceCube Neutrino ...

The highest-energy photon ever seen from a cosmic blast should have been absorbed en route, and quantum gravity may explain why it wasn't.

On March 21, 2026, China's Einstein Probe space telescope caught a seven-minute flash of soft X-rays from a galaxy 500 million light-years away — and in doing so, captured only the second confirmed ...
