Super-Earth TOI-561b is about 40 times closer to its host star than Mercury is to the sun.

After decades of searching, astronomers may have finally stumbled upon the first moon known to exist beyond our solar system—and it's an absolute giant.

Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.

To test this idea, the new study looks at an exoplanet known as VHS 1256b. It has a mass of around 20 Jupiters and is one of ...

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 ...

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

JWST has captured exoplanet Tylos shedding its atmosphere into two giant tails, revealing how extreme stellar radiation can ...

The James Webb Space Telescope (JWST) has notched another milestone, capturing a direct image of a distant, frigid planet in a solar system unlike our own, astronomers announced on June 10. The ...

The discovery of new exoplanets can help scientists understand how planets form and evolve. Scientists from UNSW Sydney have located a potential new exoplanet -- a planet that orbits a star outside of ...

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 ...

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 ...

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 ...
