Images taken with the MIRI infrared camera on the James Webb Space Telescope (JWST) have made it possible to observe the ...

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which ...

There are several candidates for the biggest star in the universe. One of them, VY Canis Majoris, is over 1,500 times the ...

Understanding how the universe transitioned from darkness to the emergence of stars marks a critical shift known as Cosmic Dawn. Yet, astronomers have struggled to unravel details about the first ...

Astronomers could use specific radio signals from the universe's earliest epoch to "weigh" the first stars in the cosmos. The investigation could reveal more about the so-called Cosmic Dawn, the ...

The study of the universe’s most ancient stars hinges on the faint glow of the 21-centimetre signal, a subtle energy signal from over 13 billion years ago.

According to a new study, magnetars—a rare type of neutron star—may have forged some of the first heavy elements in the universe, based on evidence found buried in 20-year-old data.

As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s not how it works. Hint: space-time is involved.

The period before the first stars illuminated their surroundings is called the Dark Ages. At this time, the universe had cooled enough to become transparent and allow light to travel. But there ...

A team from the Flatiron Institute in New York City calculated that giant flares emitted by magnetars — highly magnetic types of collapsed stars known as neutron stars — could be the long ...
