Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), have led the most extensive observational study to date of runaway massive stars, which includes an analysis of the rotation and binarity of these stars in our galaxy.

When I say that the universe is 13.77 billion years old, it sounds rather authoritative.

Astronomers haven't found many gas giants orbiting white dwarfs. But is that because they're so difficult to spot? Or is it because their survival rate is so low? New research probes the issue.

The proposed installation — less than 10 miles from Paranal Observatory — sparked international concern. Now it’s canceled.

Experts have sounded the alarm over NASA’s decision to use a heat shield design for Artemis II that may be riskier than the space agency claims

An AI search through decades-old spacecraft images reveals that Mercury may still be alive and kicking, geologically speaking.

A full moon is seen shining over NASA’s SLS (Space Launch System) and Orion spacecraft, atop the mobile launcher in the early hours of February 1, 2026.

A full moon is seen shining over NASA’s SLS (Space Launch System) and Orion spacecraft, atop the mobile launcher at Launch Pad 39B at NASA’s Kennedy Space Center in Florida in the early hours of February 1, 2026.

The agency concluded a wet dress rehearsal for the agency’s Artemis II test flight early Tuesday morning, successfully loading cryogenic propellant into the SLS (Space Launch System) tanks, sending a team out to the launch pad to closeout Orion, and safely draining the rocket. The wet dress rehearsal was a prelaunch test to fuel the rocket, designed to identify any issues and resolve them before attempting a launch. To allow teams to review data and conduct a second wet dress rehearsal, NASA now will target March as the earliest possible launch opportunity for the flight test.
