Red Planet’s interior may not churn much

The magma fueling a Martian volcanic system remained largely unchanged for billions of years, analysis of a newfound meteorite suggests.

Weird wave found in Venus’ wind-whipped atmosphere

A 10,000-kilometer-long gravity wave arched across the upper atmosphere of Venus. The feature may have been the largest of its kind in the solar system.

The moon is still old

New analysis of moon rocks points to our satellite forming about 4.51 billion years ago, roughly 60 million years after the start of the solar system.

Planetary Science

Many tiny moons came together to form moon, simulations suggest

Earth’s moon formed from mini-moons generated by a series of medium to large impacts, rather than from one colossal collision, researchers propose

Dawn spacecraft maps water beneath the surface of Ceres

Water ice sits just beneath the surface and within some permanently shadowed craters of the dwarf planet Ceres.

Planetary Science

Moon’s lava tubes could be colossal

Lava tubes inside the moon could remain structurally sound up to 5 kilometers across and offer prime real estate for lunar colonists.
