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 ...

NASA's Transiting Exoplanet Survey Satellite (TESS) has made a fascinating discovery, locating a new exoplanet that falls in size between Earth and Venus. This finding has piqued the interest of ...

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 ...

A star's magnetic field must be considered in order to correctly determine the characteristics of exoplanets from observations by space telescopes such as Kepler, James Webb, or PLATO. Researchers ...

Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. The signal suggests that the Earth-size planet may have a ...

(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 ...
