In the past month, Earth experienced some of its shortest days on record. The planet spun quickly enough to shave 1.4 milliseconds off of its usual 24-hour day. These natural accelerations in Earth’s ...

How can scientists use spin as a fossil record for planetary evolution? This is what a recent study accepted for publication in The Astronomical Journal hopes to address as a team of scientists ...

For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an object that is orbiting a star at a distance, they would often assume it ...
