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 ...

This exoplanet transit shows background stars that could be biasing calculations of the exoplanet's size. Credit: Nikolai Berman/UC Irvine New research suggests that scientists (and their computer ...

Dreams of finding a sort of Earth 2.0 motivate much of the thinking around the search for exoplanets. But there is more to ...

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, ...

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.

Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a ...
