University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. An unusual binary star system shows that massive stars can completely ...

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The ...

A flash of energetic light lasts only ten seconds, yet it has completely turned around our understanding of the timeline for ...

Imagine watching a massive star that's been burning steadily for millions of years suddenly dim, fluctuate, and then vanish completely from the night sky. This isn't science fiction. It's happening ...

The current generation of gravitational wave detectors could "hear" the explosive supernova collapse of dying stars over 65 million light years away. When you purchase through links on our site, we ...

"The best-case scenario for axions is Fermi catches a supernova. It's just that the chance of that is small." When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

A novel astronomical event, termed a "superkilonova," is proposed to explain the coincident detection of gravitational waves (S250818k), indicating a subsolar-mass neutron star merger, and an ...

After a hot, compact neutron star forms from the collapsed iron core of a massive star, axions should be produced in immense quantities for about 10 seconds. Some of these axions (a, red dotted line) ...

At a very early age, children learn how to classify objects according to their shape. Now, new research suggests studying the shape of the aftermath of supernovas may allow astronomers to do the same.

Massive stars, those with initial masses exceeding eight times that of the Sun, undergo complex evolutionary processes that ultimately culminate in spectacular supernova explosions. During their ...

(Nanowerk News) One day, the star at the center of our own solar system, the Sun, will begin to expand until it engulfs Earth. It will then become increasingly unstable until it eventually contracts ...
