Deep canyons in the Andes are the perfect location to catch the most energetic particles in the universe. Carlos Argüelles-Delgado reveals how these intergalactic envoys could help prove the quantum n ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

A new study explains how some supernovas are particularly dazzling—the glow from a magnetic, spinning ball of neutrons called a magnetar. An assist from Einstein is what settled the case ...

A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun. But some - a small ​fraction - ...

A new image captured by the Very Large Telescope reveals stars and gas orbiting the "invisible giant" at the heart of our galaxy.

A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...

Using the James Webb Space Telescope, an international team of researchers has discovered chemical fingerprints from enormous ...
