SANTA CRUZ — Xi Zhang, a professor of Earth and planetary science at UC Santa Cruz, has discovered that an exoplanet classed as a “super-Jupiter” has substantial differences from our solar system’s ...

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, ...

Exoplanets are planets outside Earth's solar system. In 1995, a gas giant named 51 Pegasi b, which orbits a star similar to Earth's sun, etched its name in history as the first exoplanet ever ...

One hundred twenty light-years from us, there is an exoplanet that can potentially host life. It’s called K2-18b, and it’s the world you’d want to visit. K2-18b isn’t exactly like Earth. It’s more ...

In astronomy, there is a concept called "degeneracy." It has nothing to do with delinquent people, but instead is used to describe data that could be interpreted multiple ways. In some cases, that ...

Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have ...

A new exoplanet candidate has just burst onto the scene, and it may be one of the best alien worlds yet on which to search for extraterrestrial life. It's just 18 light-years away: a super-Earth named ...
