When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

Some of the most spectacular images ever captured by the Hubble Space Telescope reveal the violent remains of exploding stars ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.

Neither the US vice president nor the secretary of state stands to gain from a show of military force that lacks a clear strategy and runs counter to the MAGA doctrine. The conflict is primarily ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

Instead of focusing on how fast the universe is expanding, they looked at the ages of some of the oldest stars in our galaxy.

The astronomical community has spent two decades wondering why the Crab Pulsar, the stellar remnant born from a supernova that Chinese and Japanese astronomers documented in the year 1054, emits radio ...

Astronomers used Webb to find the star behind supernova 2025pht, revealing how thick dust can hide massive red supergiants.

For the first time, we have a front-row seat to one of the most violent events in the universe: a supernova. But there’s a catch - the shape of the explosion was not what we expected. In this video, ...

An international team of astronomers has carried out photometric and spectroscopic observations of SN 2024abvb—a recently ...

The star’s surface temperatures had increased by more than 1,000 degrees Celsius (1,800 Fahrenheit), turning its signature red color to yellow. It also shrank as a result of becoming hotter, going ...

We all have a concept of reality. We know what is “fact” and what isn’t. However, the truth of the matter is that the definition of “real” is a mere construct of the brain. If that didn’t blow your ...
