Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can explode not once, but twice before fading forever. Using the European Southern ...

All supernovae are exploding stars. But the nature of a supernova explosion varies quite a bit. One type, named Type 1a supernovae, involves a binary star where one of the pair is a white dwarf. And ...

Stars at the center of the Milky Way galaxy, via the Spitzer Space telescope - credit NASA, JPL-Caltech, S Stolovy (SSCCaltech). Our understanding of the universe remains solid, say astronomers whose ...

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical characteristics? This is what a recent study published in Nature Astronomy hopes to ...

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 ...

Alex Filippenko is the kind of guy who brings a telescope to a party. True to form, at a soiree on May 18 this year, he wowed his hosts with images of star clusters and colorful galaxies — including ...

Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies. However, key aspects of them are notoriously difficult to simulate accurately in reasonably short amounts ...

On the evening of Sunday, January 12, the SaddleBrooke Skygazers Astronomy Club will present Christa DeCoursey, a fourth-year PhD student at the University of Arizona and a member of the James Webb ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...

Humankind has long turned to the skies in search of answers. Accounts of supernovae – exploding stars – go back thousands of years, but while we know today that these events create the building blocks ...
