Astronomers have found a way to determine an asteroid’s interior structure based on how its spin changes during a close encounter with Earth.

Refining current opacity models will be key to unearthing details of exoplanet properties — and signs of life — in data from the powerful new telescope.

Day and night, and across seasons, the instrument generates breathable oxygen from the Red Planet’s thin atmosphere.

The moon sustained twice as many impacts as can be seen on its surface, scientists find.

Just 33 light years from Earth, the system appears to host two rocky, Earth-sized planets.

The varied surface suggests a dynamic history, which could include metallic eruptions, asteroid-shaking impacts, and a lost rocky mantle.

A new technique can safely guide an autonomous robot without knowledge of its environmental conditions or the size, shape, or location of obstacles it might encounter.

Among thousands of known exoplanets, MIT astronomers flag three that are actually stars.

The planet’s night side likely hosts iron clouds, titanium rain, and winds that dwarf Earth’s jetstream.

A levitating vehicle might someday explore the moon, asteroids, and other airless planetary surfaces.
