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…
A project lead by an international team of researchers uses publicly available data with images of the sky dating as far back as to the…
University of Central Florida researchers discover mechanisms for the cause of the Big Bang. Knowing the criteria behind the Big Bang explosion will be key…
Scientists observe year-long plateaus in decline of type Ia supernova light curves, which is a surprising finding as astronomers had expected that the light curve…
In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire…
A renegade star exploding in a distant galaxy has forced astronomers to set aside decades of research and focus on a new breed of supernova…
Did ancient supernovae induce proto-humans to walk on two legs, eventually resulting in homo sapiens with hands free to build cathedrals, design rockets and snap…
Dust particles form as dying red giant stars throw off material and become part of interstellar clouds of various sizes, densities and temperatures. This cosmic…
The end of a star’s life can occur in a tranquil manner in the case of low mass stars, such as the Sun. This is…
Cassiopeia A, the youngest known supernova remnant in the Milky Way, is the remains of a star that exploded almost 400 years ago. The star…
A Caltech-led team of researchers has observed the peculiar death of a massive star that exploded in a surprisingly faint and rapidly fading supernova. These…
