The large and distant planet may be adding a wobble to the solar system, giving the appearance that the sun is tilted slightly

Called CubeSats, swarms of these small marvels could potentially take on NASA's riskiest missions, at a lower cost than full-size, multi-instrument satellites

Researchers found that the bulk soil on Mars, across regional scales the size of the U.S. or larger, likely contains iron sulfates bearing chemically bound water, which typically result in acidic brines

The first high-resolution images of the gas giant Jupiter are still a few weeks away

The orbit of such a planet had been expected to be unstable, probably resulting in the planet being quickly ejected from the system, but somehow this one survives

Hot, rocky planets may change their composition if rock components vaporize in steam atmospheres that escape to space

Curiosity rover's discovery of manganese oxide points to a more Earth-like planet

Researchers ditch approximations, find small-scale structures produce important effects using new computer codes

“This phenomenon can vary sea level by as much as 10 cm along the Colombian and Venezuelan coast," researcher says

New research findings will help mitigate effects of extreme space weather
