Stars and planets are inextricably linked. They form together and stars shape the fate of planets. Stars create the dusty protoplanetary disks that give birth to planets of all kinds. And when a star ...

As the number of exoplanet detections has breached 6,000 and continues to grow, scientists are finding a wide variety of ...

For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

Spin separates giant planets from 'failed stars' Clearest evidence yet that giant planets spin faster than their cosmic ...

In the future, this feature could be used to shed light on chemistry and even the birth of planetary systems.

Many astronomical objects play by clear rules and fit into neat categories, but brown dwarfs (celestial objects too massive to be mere planets, but too small to be real stars) continue to refuse to ...

This image from a simulation of atmospheric flow shows temperature patterns on one of the newly discovered planets (61Virb), which is hot enough that it glows with its own thermal emission. A movie of ...
