Scientists at CU Boulder are developing a satellite about the size of a toaster oven to explore one of the cosmos' most fundamental mysteries: How did radiation from stars punch its way out of the first galaxies to fundamentally alter the make-up of...

Of all the stars in the sky, one in the strangest is known as Betelgeuse. Eventually, the star will die in a supernova explosion, but that could be another 100,000 years away. Scientists have been studying the star intently since late 2019, when the...
In late 2019, Betelgeuse, the star that forms the left shoulder of the constellation Orion, began to noticeably dim, prompting speculation of an imminent supernova. If it exploded, this cosmic neighbor a mere 700 light-years from Earth would be...

NASA and the ESA have released a timelapse clip of images captured by the Hubble Space Telescope showing a supernova slowly dying far away.
The supernova took roughly a year in Earth time to go from incredibly bright to dull and dim.

In its 4.5 billion year history, Earth has had to run the gauntlet. Numerous catastrophes have imperilled the planet, from massive impacts, to volcanic conflagrations, to frigid episodes of snowball Earth. Yet life persists. Among all of the hazards...

Massive stars end their lives with energetic explosions known as supernovae. Stripped-envelope supernovae show weak or no traces of hydrogen in their ejecta, meaning that the star loses most or all of its hydrogen-rich outer layers before exploding.

One-hundred million light years away from Earth, an unusual supernova is exploding.
It’s kind of hard to see inside a star as it’s blowing up, because of the whole “blowing up” part, but gravitational waves – tiny ripples in the fabric of spacetime itself – may help astronomers unlock how the...

NASA's Hubble telescope spotted a wispy orange ribbon in space, but it's actually the destructive blast wave of a supernova.
The supernova is located in the Cygnus constellation and is roughly 2,400 light-years from Earth.
Hubble has now spent...

The gas and dust cast off by a supernova explosion keeps moving at a high speed for centuries.
The post Supernova Wreckage is Still Expanding at Extreme Speeds After 400 Years appeared first on Universe Today.
359 million years ago the Earth suffered one of its worst extinction events, and a team of researchers at the University of Illinois think that it might be caused by a series of supernova explosions no more than 35 light years away. Every once in a...
A supernova, the explosion of a white-dwarf or massive star, can create as much light as billions of normal stars. This transient astronomical phenomenon can occur at any point after a star has reached its final evolutionary stages.
