Researchers have found a clever new way to map a part of Earth’s upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they ...

Our rocky planet sister?

Scientists made a first-of-its-kind discovery: key ingredients for life detected on a habitable-zone planet, upending long-held assumptions.

This model reveals how vastly different the atmosphere was on ancient Earth, and how life may have first emerged. The key to unlocking the secrets of distant planets starts right here on Earth.

While the celestial body seems to host three features that could make a livable environment—an atmosphere, a rocky composition and a temperature that could allow liquid water to sit on the surface—res ...

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.

Earth has approximately one billion years of habitability left. That deadline has nothing to ...
