Determining the size of an Earth-size exoplanet by the amount of starlight it blocks hundreds of light-years away once was the realm of science fiction. Measuring the mass of such a small planet based ...

New research using NASA’s James Webb Space Telescope examines the maximum sizes of gas giant exoplanets, measuring chemical compositions and formation processes in the HR 8799 system.

This exoplanet transit shows background stars that could be biasing calculations of the exoplanet's size. Credit: Nikolai Berman/UC Irvine New research suggests that scientists (and their computer ...

In a zesty new discovery, scientists have unearthed a strange lemon-shaped exoplanet. It is unlike one we have seen before, challenging many of the previously held assumptions about planetary ...
