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 ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

In our galaxy, a supernova explodes about once or twice each century. But historical astronomical records show that the last Milky Way core-collapse supernova seen by humans was about 1,000 years ago.

Astronomers are puzzling over an oddball gamma ray burst that may have accompanied a supernova that is still in the process of brightening. NASA’s Swift satellite detected a burst of high-energy gamma ...

In this edition of Cosmically Cosmically, host Patrick McNameeKing sits down with St. Anselm College astronomer Nicole Gugliucci to chat about a moment in history that changed astronomy forever. In ...

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.
