The unusual system of three “super puff” planets has at least one more planet, revealed by its gravitational tug on other planets An unusual planetary system with three known ultra-low density ...

Some 2,600 light-years from our own Solar System dwells one of the most peculiar planetary systems in the entire galaxy. Called Kepler-51, the Sun-like yellow dwarf star was found in 2012 to have ...

Using the James Webb Space Telescope (JWST), astronomers have discovered a fourth world in a strange system of ultralight "super puff" planets. The new extrasolar planet or "exoplanet" was discovered ...

Astronomers once believed that most solar systems would be much like our own, with small rocky planets near their sun, accompanied by gas giants orbiting the star at greater distances. Beginning in ...

How many exoplanets are in the cosmos and what can they tell us about planetary formation and evolution? This is what a recent study published in The Astronomical Journal hopes to address as an ...

Astronomers have discovered one of the most puffed-up planets yet 1. Known as TOI-1420b, it has just 1.5% the density of Earth, making it one of the least-dense among the more than 5,000 extrasolar ...

Since astronomers found that there were planets around other stars, there has been a big effort to locate these exoplanets and learning what we can about them. These planets are, after all, where life ...

The James Webb Space Telescope has caught a rare kind of exoplanet in the act of falling apart, revealing a world so light and distended that astronomers compare it to a ball of cotton candy. The ...
