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.

Astronomers have uncovered a potentially habitable Earth-sized exoplanet 300 light-years away from us. Out of the 2,681 exoplanets spotted by NASA's Kepler space telescope between 2009 and 2018, this ...

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 ...

In 2025, astronomers sharpened their view of the planetary system around Proxima Centauri — the sun's closest stellar ...

Xi Zhang, a professor of Earth and planetary science at UC Santa Cruz, has discovered that an exoplanet classed as a ...

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 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 ...

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 ...

One of the primary goals of the James Webb Space Telescope (JWST) is to detect atmospheres around exoplanets, to try to suss ...

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 ...

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 ...
