The heat from this cataclysmic event produces a shock wave – similar to a sonic boom from a supersonic jet – that races outwards through the rest of the doomed star, producing new elements by nuclear reactions as it goes...

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. It is likely that large amounts of dust between...

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...

From NASA Feb 8, 2021  Back to Gallery Astronomers may have found our galaxy’s first example of an unusual kind of stellar explosion. This discovery, made with NASA’s Chandra X-ray…

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 disaster when the radiation devastates life as we know it.

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 space, forming a dust cloud...

Holding out hope for alien life somewhere out there? According to a recent study from Cardiff University, you may have to wait a long, long time - if phosphorus isn't present, it could be difficult for that life to exist...

Researchers at the Technical University of Denmark have learned that cosmic rays emitted when stars explode have a measurable impact on weather patterns on Earth...

Legions of scientists have studied and taken images of the Crab Nebula -- in fact, it's one of the most-studied object in space. But until now, astronomers have never been able to glimpse the object at the heart of the massive...

NASA’s Kepler telescope managed to record, for the first time ever, the early shockwave of an exploding star, and it was quite a coincidence. The light captures, reconstructed into ‘footage,’ reveal the bright “shock...

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 at first glance you might conclude...
