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

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.

How any Earth-sized exoplanets exist, and how do we find them? This is what a recent study published in The Astrophysical Journal Letters hopes to address | Space ...

An international team of professional and amateur astronomers, using simple off-the-shelf equipment to trawl the skies for planets outside our solar system, has hauled in its first “catch.” The ...

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.

When the first exoplanet was discovered in 1995, Sara Seager and Dave Charbonneau were graduate students at Harvard. Both were studying topics totally unrelated to planets orbiting distant stars. Yet ...

Only 11.4 light-years away, two exoplanets have been detected around a neighboring star. One of them, Gl725Bc, is located in the habitable zone and is now the second closest potentially ...

With this new survey, astronomers have gained a peek inside a stage of exoplanet system formation they have yet to fully explore ...
