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 ...

The James Webb Space Telescope is turning distant exoplanets from anonymous dots of light into worlds with weather, chemistry, and sometimes even hints of clouds. By dissecting the faint starlight ...

Scientists say they have possibly identified a lava world so dramatic that it might boast a thin regional atmosphere of vaporized rock where it is closest to its star. That exoplanet is called K2-141b ...

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system. The most likely reason (when combined with other observation) for seeing 1000 times more of ...

On Earth, water is so intertwined with life that our search for life on other worlds is essentially a search for water. When scientists find exoplanets around distant stars, a primary consideration is ...

When scientists discovered the first planet orbiting another star in 1995, few outside astronomy circles noticed. That planet, 51 Pegasi b, opened the door to a field that now boasts more than 5,000 ...
