Astronomers have used the James Webb Space Telescope (JWST) to discover that a distant "hot Jupiter" planet has two ...

After decades of searching, astronomers may have finally stumbled upon the first moon known to exist beyond our solar ...

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 ...

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 ...

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 a rocky molten exoplanet with an atmosphere teach astronomers about planetary formation and evolution? This is what ...

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 ...

Astronomers say they've found what may be the smallest and most distant planet known to be orbiting a star outside our own solar system. The work suggests that such small rocky or icy planets may be ...

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 ...
