A new exoplanet model screens rocky worlds by their ability to retain atmospheres over geologic timescales, helping narrow ...

A Stanford scientist's model suggests many small rocky planets can't sustain atmospheres, potentially explaining the scarcity ...

What can exozodiacal dust, also called exozodi, teach astronomers about identifying Earth-like exoplanets? This is what a recently submitted NASA white paper—which highlights key findings from the ...

Astronomers have found some pretty wild exoplanets. Some are balls of lava the temperature of hell, one is partially made of diamond, and another may rain molten iron. However, not all exoplanets are ...

Finding life beyond our solar system is a major goal of modern astronomy. NASA's planned Habitable Worlds Observatory (HWO) aims to take direct ...

Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a ...

Image of the disk around the star TWA 7 recorded using ESO’s Very Large Telescope’s SPHERE instrument. The image captured with JWST’s MIRI instrument is overlayed. We can clearly see the empty area ...

Left: Artistic conception of the longheld astronomical assumption of brown dwarfs resembling Jupiter in appearance, displaying prominent multiple zonal bands and stable vortices similar to the Great ...

Astronomers using the James Webb Space Telescope have captured breathtakingly detailed images of two giant exoplanets orbiting a distant sun-like star. These observations revealed sand-like silicate ...

SANTA CRUZ — Xi Zhang, a professor of Earth and planetary science at UC Santa Cruz, has discovered that an exoplanet classed as a “super-Jupiter” has substantial differences from our solar system’s ...
