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 ...

An artist’s rendering of the exoplanets identified by the survey. The planets are not to scale, ranging from roughly Earth-sized at the top of the image, to Jupiter-sized at the bottom. Planets ...

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 ...

Hot Jupiters – giant gas planets that race around their host stars in extremely tight orbits – have become a little bit less mysterious thanks to a new study combining theoretical modeling with ...

A team of astronomers led by Penn State scientists have discovered a planet that has the most oblong orbit ever found among transiting planets. The exoplanet’s extreme circuit — which looks closer to ...

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 ...

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 ...
