SN2015bh—the end of a star or an 'impostor' supernova?

Massive stars end their lives in supernova explosions, highly energetic events that can be as luminous as the entire starlight from their host galaxies. However, there are events called "supernova impostors" which, despite ...

Thirty years ago, on 23 February 1987, the light from a stellar explosion marking the death of a massive star arrived at Earth to shine in Southern Hemisphere skies.

Launched on 10 December 1999, XMM-Newton is an X-ray observatory designed to investigate some of the most violent phenomena in the Universe. Sources that emit large amounts of X-rays include remnants of supernova explosions ...

The Super-Kamiokande detector awaits neutrinos from a supernova

Only three or four supernovas happen in our galaxy every century. These are super-energetic events that release neutrinos at the speed of light. At the Super-Kamiokande detector in Japan, a new computer system has been installed ...

Young magnetar likely the slowest pulsar ever detected

Using NASA's Chandra X-ray Observatory and other X-ray observatories, astronomers have found evidence for what is likely one of the most extreme pulsars, or rotating neutron stars, ever detected. The source exhibits properties ...

Supernova ejected from the pages of history

A new look at the debris from an exploded star in our galaxy has astronomers re-examining when the supernova actually happened. Recent observations of the supernova remnant called G11.2-0.3 with NASA's Chandra X-ray Observatory ...

Blue is an indicator of first star's supernova explosions

An international collaboration led by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have discovered that the color of supernovae during a specific phase could be an indicator for detecting ...
