The varied surface suggests a dynamic history, which could include metallic eruptions, asteroid-shaking impacts, and a lost rocky mantle.
New findings may help explain how Earth’s crust forms, the location of ore deposits, and why some volcanoes are more explosive than others.
Among thousands of known exoplanets, MIT astronomers flag three that are actually stars.
Scientists propose a new mechanism by which oxygen may have first built up in the atmosphere
Over more than three decades at MIT, Binzel developed key insights into the solar system and played a role in multiple NASA missions.
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.
A new study shows it’s theoretically possible. The hypothesis could be tested soon with proposed Venus-bound missions.
Report led by MIT scientists details a suite of privately-funded missions to hunt for life on Earth's sibling planet.
The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.
Such planetary smashups are likely common in young solar systems, but they haven’t been directly observed.
The cosmic boundary, perhaps caused by a young Jupiter or an emerging wind, likely shaped the composition of infant planets.
