Of the thousands of single-star systems in our galaxy, around 10% are known to have planets. Scientists thus expected about ...

Exoplanet science has entered an exciting new phase with the development of the EXCITE mission, a groundbreaking project ...

What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.

Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination ...

The atmospheres of exoplanets have been a focal point of the field lately, with the James Webb Space Telescope taking a look at as many as it can manage. But time on the world's most powerful space ...

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

Add Yahoo as a preferred source to see more of our stories on Google. In our solar system, Earth is one of but eight planets – nine, if you really want to count Pluto – and the only one remotely ...

Relatedly, astronomers may have just pushed the upper size limit of what counts as a planet.

The team of astronomers behind the find suggested it could help us better understand planet and moon formation in our solar system and beyond the Milky Way. The team was able to make the first-ever ...

The James Webb Space Telescope has directly observed the key chemical of carbon dioxide in planets outside of our solar system for the first time, scientists announced Monday. The gas giants are not ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

How can astronomers develop better methods for blocking the intense starlight of an exoplanetary system and reveal the exoplanets hiding underneath the glare? This is what a recent study published in ...
