When astronomers discovered WOH G64, the star was a red supergiant and possibly the largest extrasolar body known at the time. Back then, astronomers estimated that the star had a radius of 649 ...

The night sky may look calm, but behind the glowing points of light lies a violent and complex process of creation. Stars, some heavier than millions of Earths, are born through fierce struggles ...

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...

In these simulations, the researchers began with a massive primordial black hole seed of about 50 million times the Sun’s mass, then followed how gas flowed into it, how stars formed nearby, and how ...

Astronomers have sought to explain the existence of supermassive black holes forming less than a billion years after the Big Bang, a timescale incompatible with standard stellar evolution processes.

Long ago, before galaxies formed into shapes we are familiar with today and before planets formed, the earliest stars ignited the young cosmic clouds. If you stood inside one of those ancient ...

But the Big Bang theory predicts that about 5% of the universe's contents should be atoms made of protons, neutrons and ...

While the Sun’s solar flares strongly correlate with sunspots, observations of more than 14,000 other stars show this is not generally the case.
