The supernova remnant Cassiopeia A is, by far, one of the strangest space formations in the Milky Way. For starters, it's one of the youngest supernova remnants in the galaxy. Additionally, its structure is so peculiar that astronomers have been puzzling for a long time over what the celestial body mi... |

Some ten years ago, the remnants of the supernova Cassiopeia A were first discovered, and astronomers were able to observe for the first time a very clear structure, with little details also visible. Now, more than a decade later, scientists using both space- and ground-based telescopes managed to get a glimpse of ho... |

Cassiopeia A is a supernova remnant located about 9,000 light years away from Earth which was created by a supernova explosion somewhere around the year 1680 and one of the brightest radio sources in the sky. Although modern observations taught much about the expanding remnant, one particular problem remained to be s... |

The newly found supernova remnant is the result of a stellar explosion that would have been seen from Earth some 140 years ago. The previous youngest supernova remnant found in the Milky Way was Cassiopeia A, resulted some 330 years ago. The current record holder, G1.9+0.3, represents to astronomers a missing link be... |
