A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Scientists debunk Area 51 alien theories, pointing towards distant planets and our own Solar System's moons as potential extraterrestrial habitats.

Observations of Exoplanet WASP-69b has uncovered a 350,000-mile-long comet-like tail. The tail is a result of its escaping ...

Join Peter, Richard and Nobel Prize winning astronomer Didier Queloz as they discuss "What If we settled on an exoplanet?".

Gas giants are enormous planets made primarily of hydrogen and helium. They may contain dense central cores, but unlike Earth, they do not have solid ...

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 ...

The largest gas giants in our galaxy blur the line between planets and brown dwarfs. How do these very large gas giants form? A team of researchers, led by the UC San Diego, used spectral data from ...

NASA has developed ExoMiner++, an AI tool that speeds up the search for exoplanets by analysing massive datasets from Kepler and TESS. The system helps scientists quickly identify promising planets.

NASA has announced the discovery of an Earth-like planet orbiting a Sun-like star that shares several other similarities with ...

Are we alone in the universe? Are we alone in the universe? The search for exoplanets—planets orbiting stars beyond our solar system—is helping scientists get closer to an answer. From hot Jupiters to ...

At the beginning of the exoplanet age, the goals were fairly simple. The first was to find as many of them as possible to flesh out our understanding of the exoplanet population. The second was to ...

Daniel Apai is a professor of astronomy, planetary sciences and optical science at the University of Arizona. He receives funding from NASA. Exoplanets are worlds that orbit other stars. They are very ...
