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 discovered an extraordinary planet that's roughly the size of Earth but is only one-tenth of our planet's age, with half of its surface likely ...

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 ...

Using the Hubble Space Telescope, scientists have discovered that a cotton-candy-like Jupiter-sized planet located around 350 light-years away is shrinking and could be on the way to becoming a ...

Astronomers have discovered an unusual Earth-sized exoplanet they believe has a hemisphere of molten lava, with its other hemisphere tidally locked in perpetual darkness. Co-authors and study leaders ...

Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion – shedding light on the formation of planets like Earth. Astronomers have made the rare discovery of ...
