Massive stars end their lives with energetic explosions known as supernova explosions. ‘Stripped-envelope supernovae’ show weak or no traces of hydrogen in its ejecta, meaning…
Between a decline in biodiversity and a series of extinction events, the Late Devonian period was not the most hospitable time on Earth. And then…
The NASA/ESA’s Hubble Space Telescope has tracked the fading light of a supernova in the spiral galaxy NGC 2525, located 70 million light years away….
When a star unleashes as much energy in a matter of days as our Sun does in several billion years, you know it’s not going…
Discovery of iron-60 and manganese-53 substantiates supernova 2.5 million years ago. When the brightness of the star Betelgeuse dropped dramatically a few months ago, some…
A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea sediments. Professor Anton Wallner, a nuclear…
Called “calcium-rich supernovae,” these stellar explosions are so rare that astrophysicists have struggled to find and subsequently study them. The nature of these supernovae and…
Astronomers have used NASA’s Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million…
Imagine reading by the light of an exploded star, brighter than a full moon – it might be fun to think about, but this scene…
Calcium-rich supernovae, a unique type of exploding stars, produce up to half of the calcium in the Universe. Astronomers using several telescopes at NOIRLab, including…
Calcium-rich supernova examined with X-rays for first time. Half of all the calcium in the universe — including the very calcium in our teeth and…
Two teams of astronomers have made a compelling case in the 33-year-old mystery surrounding Supernova 1987A. Based on observations of the Atacama Large Millimeter/submillimeter Array…
For just the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type…
An exploding white dwarf star blasted itself out of its orbit with another star in a ‘partial supernova’ and is now hurtling across our galaxy,…
Nestled in the constellation Taurus, a spectacle of swirling cosmic gases measuring half a dozen lightyears across glows in shades of emerald and auburn. The…
A team of scientists, including Chief Investigator Ilya Mandel from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) at Monash University, recently submitted…
In a study recently published in the Monthly Notices of the Royal Astronomical Society, researchers Dr. Jade Powell and Dr. Bernhard Mueller from the ARC…
For most of the 20th century, astronomers have scoured the skies for supernovae—the explosive deaths of massive stars—and their remnants in search of clues about…
