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 ...

NASA’s Transiting Exoplanet Survey Satellite has identified TOI-4616 b, an Earth-sized planet transiting a cool M4 dwarf star in the solar neighborhood. The discovery, detailed in a new preprint, adds ...

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 ...

A recent study published in The Astronomical Journal uses data from the NASA K2 mission to examine the reasons behind why some exoplanets, specifically sub-Neptune exoplanets, are losing their ...

Planets around massive B-type stars at intermediate orbital distances remain largely unexplored. Here, the authors show that four evolved planet-hosting stars, HD 2952, HD 120084, HIP 65891, and HIP ...

An international team of astronomers reports the discovery of a new exoplanet orbiting a solar-type star. The newfound alien world, designated TOI-1135 b is young, hot and comparable in size to Saturn ...

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.

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 ...

700 light years away from Earth in the constellation Virgo, the planet WASP-39b orbits the star WASP-39. The gas giant, which takes little more than four days to complete one orbit, is one of the best ...
