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 ...

From the brightness variations of its host star, an exoplanet’s size and other properties can be determined. In order to avoid mistakes, the star’s magnetic field is decisive 700 light years away from ...

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 ...

What planet is most like Earth? Reseachers have identified several exoplanets similar to our planet, but none that are an ...

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 ...

A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is ...

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 ...

"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 ...

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 ...
