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

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

Scientists from UNSW Sydney have located a potential new exoplanet—a planet that orbits a star outside of our solar ...

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 ...

This is an artist's rendering of the YSES-1 system, which has two gas giant planets. See how the James Webb Space Telescope imaged them in infrared below. Webb usually observes exoplanets through ...

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 ...

Thirty years ago, astronomers didn’t know if planets around other stars were common. Today, NASA says we’ve confirmed 6,000 exoplanets — a staggering number considering the first definitive discovery ...

What can carbon dioxide in an exoplanet’s atmosphere teach us about its formation and evolution? This is what a recent study published in The Astrophysical Journal hopes to address as an international ...

A recent discovery of a “newborn” exoplanet could help scientists explain how our own home world came to be. In a study published Wednesday in the journal Nature, astronomers describe the youngest ...

Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’. In research ...

NASA released dramatic new findings from the planet-scouting Kepler spacecraft project Thursday. Looks like the universe is way, way more crowded than we had realized. The Space Administration ...

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 ...
