A rocky exoplanet outside the Earth's solar system may have an atmosphere, according to new evidence gathered by NASA researchers. The exoplanet, known as super-Earth TOI-561b, was discovered in 2020, ...

Discovery led by UC Santa Cruz Ph.D. of daily cloud cycle on a hot Jupiter exoplanet provides unique window into its make-up ...

Just a few decades ago, when we glanced skyward, we didn't know for certain whether any star visible to the naked eye hosts planets like our own. Now, NASA scientists estimate that, on average, there ...

Astronomers from the University of New Mexico, along with U.S. and international researchers, have confirmed the existence of a new giant exoplanet, made possible through a collaboration with citizen ...

How many planets outside our solar system, known as exoplanets, exist throughout the Milky Way Galaxy? While that might never be determined, NASA recently announced the total number of confirmed ...

A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is ...

Although astronomers have directly imaged a few dozen gas giants on the scale of Jupiter, Earth-sized planets are too small and dim to be directly imaged. That's not to say there's a shortage of Earth ...

What role can the relationship between oxygen (O 2) and ozone (O 3) in exoplanet atmospheres have on detecting biosignatures? This is what a study submitted to Astronomy & Astrophysics hopes to ...

These worlds are among the least dense ever found, and all attempts to probe their atmospheres have been blocked by a mysterious smog. Using the James Webb Space Telescope, astronomers have discovered ...
