Exoplanets

"If they're out there, this analysis lets us figure out where they could be living."

Astronomers using NASA's Transiting Exoplanet Survey Satellite (TESS) have identified eight new super-Earths that orbit close to their host stars.

NASA's Kepler Space Telescope spotted a seven exoplanet system with worlds being battered by radiation from their parent sun-like star just before its retirement in 2018.

Planets like Earth shouldn't get too close to their bigger, bullying neighbors. Jupiter-size worlds can wreck life-friendly conditions on their smaller neighbors.

A better understanding of exoplanet orbits is helping SETI astronomers reduce their computational costs and conduct their search for intelligent aliens faster.

A new analysis shows Jupiter-like planets likely exist around young, moving stars — suggesting our solar system formed from a quiet, low-density environment.

Almost twice as big (but half as massive) as Jupiter, WASP-17b burns at a temperature of 1,500 degrees Celsius.

Evidence pointing toward the possible existence of “Planet 9” lurking at the edge of the solar system may actually mean we need to revise our recipe for gravity.

Astronomers have observed two super-Earths colliding in a faraway system for the first time, suggesting such violent impacts are not limited to very young cosmic neighborhoods.
