For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive than planets but too small to ignite nuclear fusion like true stars. Through a ...

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 ...

For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive than planets but too small to ignite nuclear fusion like true stars. Through a ...

Heavier than Jupiter, but lighter than a small star, brown dwarfs are difficult to distinguish from giant planets. For years, astronomers have searched for a yardstick that can separate the giant ...

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 ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...
