Our rocky planet sister?

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 ...

The search for life beyond Earth has marked a new discovery — evidence of an atmosphere on an Earth-like planet beyond our Solar System with modelling suggesting it may be a water world.

Operating a million or more data centers in space would mean a massive increase in air pollution from rocket launches and concentrations of toxic ash from reentering satellites.

Astronomers have discovered more than 6,200 exoplanets since the first ones were found in the 1990s.

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

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 ...

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.
