Scientists have confirmed that a “stabilizing feedback” on 100,000-year timescales keeps global temperatures in check.
Astronomers have found a way to determine an asteroid’s interior structure based on how its spin changes during a close encounter with Earth.
A “grazing encounter” may have smashed the moon to bits to form Saturn’s rings, a new study suggests.
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.
