Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

NASA’s Hubble Space Telescope revisits the Crab Nebula, showing the movement of filaments and changes in gas composition over ...

The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

Astronomers have identified a newborn magnetar as the power source behind SN 2024afav, a superluminous supernova whose brightness far exceeded what standard explosion models could explain. The finding ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar death using general relativity.

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 many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the universe. For Joseph Farah, a fifth-year graduate student at UC Santa Barbara ...
