NASA scientists have devised a new way to use planets that cross, or "transit," the face of their parent stars to investigate stellar "spottiness." The new technique, called the "StarryStarryProcess," ...

Astronomers have long relied on two main methods to detect exoplanets—the transit method, which looks for dips in a star’s brightness when a planet passes in front of it, and the radial velocity ...

Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of ...

Astronomers have discovered a new exoplanet — but this time, the way they found it may be as significant as the discovery itself. Researchers used a breakthrough combination of indirect and direct ...

Although astronomers have found thousands of exoplanets, the number of confirmed exomoons—and exorings—is still zero. But ...

Scientists using NASA's Transiting Exoplanet Survey Satellite (TESS) discovered an exoplanet, which NASA defines as “any planet beyond our solar system.” What's False However, the “strange signals” ...

A new analytical transmission model incorporating pressure-dependent opacity improves interpretation of exoplanet atmospheres and supports data analysis from JWST and the upcoming ARIEL mission.
