Super-Earths can exist in wider orbits around their parent stars than was previously believed, suggesting these Earth-like exoplanets could be more common than we thought.
Astronomers discovered a planet that orbits its star so closely that its surface is being scorched into magma and vaporizing into space.
Scientists have found further evidence of possible biosignature gases on the planet K2-18b, strengthening its case as an abode for alien life. But the case is far from closed.
Astronomers have discovered the weirdest planetary system ever seen, consisting of a planet rolling around rare binary "failed star" brown dwarfs at a 90-degree tilted angle!
An AI algorithm designed to look for planetary systems that could host Earth-like, habitable zone planets, has found 44 candidates.
A nearby Earth-sized planet beyond our solar system could soon add to the diversity of known terrestrial worlds with their own "air."
New insights into the chemistry of exoplanet atmospheres indicates planet-wide rainfall might take place following hydrogen atmosphere and water mixing.
A new study compares young and old exoplanets to uncover how worlds shrink, migrate and evolve over time — offering insights into long-standing astronomical mysteries like the "hot Neptune desert" and the "radius valley."
A newly found super-Earth could help provide answers as to why there are hardly any planets twice the diameter of Earth.
Astronomers have discovered two new exoplanets that are similar to other worlds found in the Milky Way, but unlike any in our own solar system.
