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.

Astronomers have combined 14 widely used catalogues into the Regalade catalogue. The catalogue provides scientists with a single resource to look up measured parameters of galaxies, significantly ...

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 ...

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 ...

A sudden, mysterious burst of bright light in the sky could be from a black hole devouring a vast, unusually bare star. In 2018, astronomers spotted a new kind of cosmic explosion that became brighter ...

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 ...

A German town has been peppered by meteorites after a stunning "fireball" exploded in the skies over central Europe. One extraterrestrial fragment landed in a bedroom after punching a soccer ball-size ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

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 ...
