Astronomers have studied 3,600 supernovas to discover diversity in exploding white dwarf stars, a vital tool in the ...

The results indicate that the elements essential for life formed within extreme, highly energetic environments deep inside stars, far removed from the calm conditions required for life itself. The ...

Gamma-ray bursts, as shown in this illustration, come from powerful astronomical events. NASA, ESA and M. Kornmesser When faraway stars explode, they send out flashes of energy called gamma-ray bursts ...

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar ...

Stars like the Sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the Sun ...

You’d think that supernovae – the death throes of massive stars and among the brightest, most powerful explosions in the universe – would be hard to miss. Yet the number of these blasts observed in ...

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical ...

Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through ...

Brad E Tucker receives funding from the Australian Research Council and ACT Government. What is the universe made of? This question has driven astronomers for hundreds of years. For the past quarter ...

Andreea Font does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

Research by a Danish physicist suggests that the explosion of massive stars – supernovae – near the Solar System has strongly influenced the development of life. Prof. Henrik Svensmark of the ...

Stars like the sun are remarkably constant. They vary in brightness by only 0.1 percent over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep ...
