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 ...

The ‘guest star’ of 185 AD has been one of astronomy's most unresolved cases for over 1800 years. Ancient Chinese chroniclers recorded a mysterious li.

"For the most part, massive stars make black holes. The more massive the star, the heavier the black hole," Fishbach said, until stars reach a certain mass threshold beyond which the physics of their ...

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 ...
