Exoplanets—planets that orbit stars beyond our solar system—have transformed our understanding of the universe. Since the first confirmed discovery in the 1990s, more than 5,000 have been identified, ...

The two exoplanets, roughly the size of Jupiter, are located 1,113 light-years away from Earth.

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 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 ...

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.

"A key step toward ultimately understanding which planets can stay alive, keep their water, and perhaps even, one day, host life as we know it." When you purchase through links on our site, we may ...

Kepler-62f (also known by its Kepler Object of Interest designation KOI-701.04) is a super-Earth exoplanet orbiting within the habitable zone of the star Kepler-62, the outermost of five such planets ...
