An international team analyzed data from NASA's Fermi space telescope and detected gamma rays from a rare and exceptionally ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

A new analysis from NASA using the Hubble Space Telescope shows that the Crab Nebula, the remnant of a supernova recorded in 1054, is still rapidly expanding, offering rare, direct evidence that the ...

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar death using general relativity. (Nanowerk News) Astronomers have used distant ...

A spinning magnetar twists space-time itself, causing the disk of material around it to wobble and produce the ultra-bright flashes of this peculiar kind of supernova. (Santa Barbara, Calif.) — For ...

Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova ...

For the first time, astronomers have witnessed the birth of one of the universe's most powerful magnets, or magnetars, at the heart of an unusually bright supernova, thanks to an effect first ...

In recent years, whenever astronomers have gazed into the night sky, they’ve noticed something peculiar: Some of its massive stars—the true titans of the cosmos—appear to be missing. The largest of ...
