The Artemis program’s timeline and architecture has changed over the past year, so Artemis III will not land on the lunar surface.
An observatory director describes the differences between the types of rocks that fly through space.
A data center could get more solar power and be kept much colder in space, but it would be extremely difficult to repair and update.
2026 has already been a banner year for meteor spottings and sonic booms across the world.
The nature of space, time and the evolution of life on Earth mean it’s unlikely extraterrestrial life has visited our home planet.
Scientists have discovered the most distant hydroxyl megamaser ever detected. This is a natural space laser.
