Exoplanets in the habitable zone of the Trappist-1 star, some 40 light-years away from Earth, are more likely to have liquid water than researchers previously thought, according to a new study.

Mild solar storms can cause more serious problems to GPS satellites than once-in-a-century events, a new study has found.

A powerful solar flare disrupted radio and navigation signals across North America on Monday and prompted space weather forecasters to issue warnings because of energetic particles hitting Earth.

A lightweight version of the International Space Station's robotic arm will help Astroscale remove decades-old space junk from Earth's orbit in the first mission of its kind.

The Cygnus NG-19 mission arrived at the International Space Station after a two-day space ride on Friday, Aug. 4, delivering supplies and equipment including a new potable water dispenser.

Legendary guitarist Brian May talks to Space.com about his collaboration with NASA's OSIRIS-REx mission and a new book about asteroid Bennu written with the mission's science lead Dante Lauretta.

Queen guitarist Brian May and the chief scientist of NASA's asteroid-sampling OSIRIS-REx mission have collaborated on a book about the asteroid Bennu — and it's not a PR stunt.

Removing carbon from Earth's atmosphere may not reverse devastating changes to weather patterns in vulnerable areas, a new study suggests.

Scientists may have just found what makes the sun's outer atmosphere, the corona, so inexplicably hot.

Queen guitarist and astrophysicist Brian May is about to release a book of 3D photographs of the near-Earth asteroid Bennu, based on images gathered by NASA's OSIRIS-Rex spacecraft.

A new unpublished study is making waves on the internet, claiming that one of the brightest stars in the night sky might die in a spectacular explosion within our lifetime.

Exponential growth in Starlink orbital collision avoidance maneuvers in the past six months is sparking concerns over the long-term sustainability of satellite operations.
