Planetary systems in the Milky Way galaxy tend to follow a particular pattern: rocky planets toward the center, closest to ...

Astronomers may finally understand why planets orbiting two suns, the real-world equivalents of the "Star Wars" planet ...

How any Earth-sized exoplanets exist, and how do we find them? This is what a recent study published in The Astrophysical ...

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

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

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 ...

Using HARPS and HARPS-N spectrographs, astronomers have observed a nearby K-type star designated HD 176986, known to host two ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists have gotten a never-before-seen look at an area around a large exoplanet 625 light-years away where moons like the one ...

In a conventional system like our own, rocky planets such as Mercury, Venus, Earth, and Mars orbit closest to the host star. Farther out, gas giants ...

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 ...

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 ...

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 ...
