Vision of a Stellar Ending
The light from this supernova first reached Earth from the direction of the constellation Cassiopeia around 1667 A.D. If anyone alive at the time saw it, they left no records.…
Reclusive Neutron Star May Have Been Found in Famous Supernova
Since astronomers captured the bright explosion of a star on February 24, 1987, researchers have been searching for the squashed stellar core that should have been left behind. A group…
Rare Blast’s Remains Discovered in Milky Way Center

Exploding stars may have caused mass extinction on Earth, study shows
Imagine reading by the light of an exploded star, brighter than a full moon – it might be fun to think about, but this scene is the prelude to a…
Hubble Finds That Betelgeuse’s Mysterious Dimming Is Due to a Traumatic Outburst
Observations by NASA’s Hubble Space Telescope are showing that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into…
Global warming is killing the stars
People send me things. Today it is a curious graph of the number of supernovae (dying stars) discovered versus the HadCRUT temperature data since 1960. There’s a good correlation. So…
