In new research, University of California, Irvine astronomers describe how more than 200 known exoplanets are likely much larger than previously thought. It's a finding that could change which distant ...

(CNN) — Astronomers have found an Earth-size planet that isn’t like Earth at all. Instead, the exoplanet, called LP 791-18 d, is likely covered in volcanoes and may experience eruptions with the same ...

The planet, named TOI 700 e, is one of four known planets orbiting a cool star approximately 100 light-years away. The planet was discovered by NASA’s planet-hunting telescope, the Transiting ...

Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.

In a recent study published in The Astrophysical Journal Letters, an international team of researchers led by the University of Kansas examined a super-Earth exoplanet, GJ 1252b, which orbits an ...

"We detected another planet even closer to the star that interacts strongly with its big neighbor, causing their orbits to wobble in ways we've never seen before." When you purchase through links on ...

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 ...
