Suzaku 'Post-mortem' Yields Insight into Kepler's Supernova

An exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun, according to an analysis of X-ray observations from the Japan-led Suzaku satellite. The findings will help astronomers better understand the diversity of type Ia supernovae, an important class ...

‘Cry’ of a Shredded Star Heralds a New Era for Testing Relativity

'Cry' of a Shredded Star Heralds a New Era for Testing Relativity

Last year, astronomers discovered a quiescent black hole in a distant galaxy that erupted after shredding and consuming a passing star. Now researchers have identified a distinctive X-ray signal observed in the days following the outburst that comes from matter on the verge of falling into the black hole.

In McNeil’s Nebula, a Young Star Flaunts its X-ray Spots

In McNeil's Nebula, a Young Star Flaunts its X-ray Spots

Using combined data from a trio of orbiting X-ray telescopes, including NASA's Chandra X-ray Observatory and the Japan-led Suzaku satellite, astronomers have obtained a rare glimpse of the powerful phenomena that accompany a still-forming star. A new study based on these observations indicates that intense magnetic fields drive torrents of ...

Suzaku Shows Clearest Picture Yet of Perseus Galaxy Cluster

Suzaku Shows Clearest Picture Yet of Perseus Galaxy Cluster

X-ray observations made by the Suzaku observatory provide the clearest picture to date of the size, mass and chemical content of a nearby cluster of galaxies. The study also provides the first direct evidence that million-degree gas clouds are tightly gathered in the cluster's outskirts

Suzaku Finds “Fossil” Fireballs from Supernovae

Suzaku Finds Fossil Fireballs from Supernovae

Suzaku studies of supernovae have revealed never-before-seen embers of the high-temperature fireballs that immediately followed the explosions. Even after thousands of years, gas within these stellar wrecks retain the imprint of temperatures 10,000 times hotter than the Sun's surface.
