Scores of exoplanets may be larger than realized
In new research, University of California, Irvine astronomers describe how more than 200 known exoplanets are likely much larger than previously thought. It's a finding that could change which distant ...
Exoplanets are planets that orbit stars other than the sun and thus exist outside the solar system. The word "exoplanet" derives from the term "extrasolar planet," which hints at its existence beyond ...
Exoplanets—planets that orbit stars beyond our solar system—have transformed our understanding of the universe. Since the first confirmed discovery in the 1990s, more than 5,000 have been identified, ...

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 ...
The NASA Kepler mission has discovered 219 more exoplanets, including 10 Earth-size planets, program scientist Mario Perez said Monday at NASA’s Ames Research Center in California. Ten of the planets ...
As missions like Kepler and TESS discovered more rocky exoplanets in recent years, scientists looked forward to the launch of the JWST. The powerful space telescope has the ability to gather infrared ...
Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.
