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 ...
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 ...

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 ...
Scientists using a NASA space telescope have discovered a tantalizing world. It's about the size of Earth, sits remarkably close to our solar system, and could be comfortable for life as we know it.
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 ...
(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 ...
