NASA’s James Webb Space Telescope captured an enlightening image of the Crab Nebula, a supernova remnant that is located 6,500 light-years from Earth. The Crab has been studied since as far back as 1054 CE by 11th-century astronomers.
The top image is a side-by-side comparison of the Crab Nebula as seen by the...

A new study has identified a chemically distinct star located in the halo of the Milky Way, stating it provides evidence of the deaths of the universe's first stars. The research team says the new find could represent the very first evidence of a pair-instability supernova (PISNe) from the early universe.

Astronomers spotted an intergalactic explosion 10 times brighter than any recorded supernova (exploding star). The event, called AT2021lwx, was first detected in 2020 and is believed to be the largest explosion ever recorded.
The event was at first thought to be unremarkable, due to the fact there was no indication...

NASA's James Webb Space Telescope (JWST) captured a sensational image of a supernova remnant created by a stellar explosion 340 years ago (as seen from Earth). The remnant, known as Cassiopeia A, is the youngest known remnant from an exploding, massive star in our Milky Way.
While the image from JWST is not the...

Astronomers have detected a one-in-ten-billion binary star system that will one day form a kilonova. The star system was found utilizing the SMARTS 1.5-meter Telescope located in Chile.
A group of astronomers at the National Science Foundation's NOIRLab announced on January 31, 2023, that they had discovered the...

The remnants of an exploded white dwarf star are serving as a learning tool for astronomers. The supernova remnant, known as SNR 0519-69.0 (SNR 0519 for short) is the result of debris from a white dwarf star explosion.
It is believed that the dwarf star in question reached a critical mass, "either by pulling matter...

A new study reveals an odd peculiarity of a massive shock wave traveling through a cloud of gas left behind by the stormy death of a star. Research suggests that part of it is traveling in the wrong direction.
Cassiopeia A is a gas cloud, or nebula, left behind by a supernova in the constellation Cassiopeia. The...

What do the final months or days of a dying star look like? Human beings have observed supernovae but there is still so much to learn about them. This includes the warning signs that different kinds of stars release. Scientists for the very first time recently witnessed the destruction of a red supergiant star several...

We don't tend to think of solid state drives as being overly susceptible to the dangers of heat, but then again, we're not running a toasty server farm or bombarding our SSDs with constant simulation applications. For those who do have a server farm to run, or are otherwise worried about longevity, Super Talent just...
