Given the incredible amounts of energy in a supernova explosion -- as much as the sun creates during its entire lifetime -- another erroneous doomsday theory is that such an explosion could happen in ...

Last night, I wrote about a possible new supernova in the galaxy M95, a nearby spiral. It has since been confirmed, and is called SN 2012aw. Given that M95 is about 37 or so million light years away – ...

The first supernova of the year was spotted a couple of weeks ago: Supernova 2012A, in the galaxy NGC 3239 in the constellation of Leo. Adam Block of the Mount Lemmon SkyCenter took a phenomenal image ...

M95 is a barred spiral galaxy located in the constellation Leo. A supernova has been newly discovered in it. Image obtained March 20, 2012. Oscar Martín Mesonero of the Salamanca Organization of ...

Using NASA’s Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a “zombie star” after an unusually weak supernova explosion. A supernova typically ...

The shapes of supernova leftovers can tell scientists the origin of this explosion, with Type 1a supernova from thermonuclear explosions leaving behind symmetric remnants (right). And supernova ...

It’s a blast from the not-too-distant past. Cassiopeia A is a giant, expanding shell of debris about 11,000 light-years away. It’s one of the youngest remnants of a supernova, an exploded star, in our ...
