Searching for exomoons—moons that orbit around another planet—was one of the most exciting capabilities expected of the James Webb Space Telescope (JWST) when it launched in late 2021. So, after four ...

Astronomers have yet to find irrefutable proof for any natural satellites of exoplanets—so-called exomoons—but as circumstantial evidence accumulates and the list of candidates grows, the discovery of ...

Exoplanet PSR J2322-2650b, orbiting a pulsar, possesses an unprecedented helium-and-carbon-dominated atmosphere, characterized by molecular carbon (C3 and C2) and soot clouds, a composition unlike any ...
