How to find hidden oceans on distant worlds? Use chemistry
A new study shows how the chemicals in an exoplanet's atmosphere can, in some cases, reveal whether or not the temperature on its surface is too hot for liquid water.

By analyzing the data from the TESS-Keck Survey (TKS), an international team of astronomers reports the detection of two almost identically sized sub-Neptune exoplanets orbiting a nearby star. The newly found alien worlds, ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new inflated, low-density "hot Jupiter" exoplanet. The newly found alien world, designated TIC 257060897b, is about 50 percent larger ...
Considered an ultra-hot Jupiter—a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain—the fiery, inferno-like WASP-76b exoplanet may be even more sizzling than scientists ...

An international team of astronomers has detected a new ultra-hot Jupiter extrasolar planet using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien world is nearly two times larger than Jupiter and has ...
About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky Way. This particular star, known as LP 40−365, is one of a unique breed of fast-moving stars—remnant pieces of massive ...
