Astronomers studying the Milky Way's oldest stars have estimated that the Universe is about 13.6 billion years old.

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

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 ...

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

Every star’s death is dramatic. Superluminous supernovae take the theatrics to another level. In the early 2000s, scientists first saw these conspicuous cataclysms, which can shine much longer and ...

A new Masters of the Universe rumour reveals who the original live-action He-Man, Dolph Lundgren, will play in Travis ...

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...

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 ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about 13.

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

Astronomers have detected a neutron star collision in an unexpected place, deep within a tiny, faint galaxy. Located about 4.7 billion light-years away, this collision occurred within a vast gas ...
