Astronomers have discovered the first evidence of magnetic worlds beyond the solar system thanks to their high-speed, violent winds, representing a major step forward in exoplanet research.
How do you weigh a planet you can't see? Astronomers may have the answer and it involves "reading between the rings," the bright beautiful structures exoplanets create.
The familiar concept of a planetary core, a small, dense metallic heart we take for granted, may be the exception rather than the rule for exoplanets.
TESS has released its most complete view of the sky over Earth, revealing the location of 6,000 potential worlds beyond the solar system.
By probing the atmosphere of a mini-Neptune exoplanet, the James Webb Space Telescope has found that it formed much farther from its star than it is today, possibly explaining the origin of many other mini-Neptunes in the process.
New simulations suggest binary star systems may be ideal for planet formation, and may produce more gas giants than single-star systems.
"Most planetary systems appear as 'peas in a pod.' This is not the case in the TOI-201 system."
Using the James Webb Space Telescope, astronomers have investigated the giant exoplanet 29 Cygni b — work that could clarify the line between planets and stars.
A new catalog of potentially habitable exoplanets provides the framework for future observations in the search for alien life.
Astronomers have discovered an additional 100 new worlds in data collected by NASA's exoplanet-hunting spacecraft TESS, thanks to an innovative AI program.
