Turbulent ocean could explain Europa’s chaotic ice
New computer simulations show turbulent global ocean currents that distribute heat unevenly and could explain the formation of the chaotic ice patterns at the moon’s lower latitudes.

Dust cloud, tail could explain exoplanet’s odd light pattern
KIC 12557548 b may be ejecting dust from its surface, creating a cometlike tail behind it and an opaque envelope of material around it.

Jupiter’s Great Red Spot explained
A computer simulation is the first to explain how Jupiter’s Great Red Spot has survived for the nearly 200 years humans have observed it.

Uninhabitable Earth
A recent estimate of the lifetimes of the habitability zones of Earth and various exoplanets suggests Earth could become unable to support life as soon as 1.75 billion years from now, when the sun brightens before dying out.

Moon’s craters remeasured
Large craters cover more of the moon’s surface on its nearside than its farside, according to new maps from NASA’s GRAIL spacecrafts.

Meteor explosions like this year’s Russian fireball more common than thought
Chelyabinsk-sized rocks may come to Earth every 30 years, on average.

Moon material on Earth
Scientists now think that tektites are a type of impactite, formed during the rapid heating and cooling of material ejected when a meteorite strikes Earth.

An Earth-sized hell circles faraway star
Kepler-78b, an Earth-sized, extremely hot exoplanet made of rock and iron, is the smallest with known diameter and mass.

Solar system with seven planets discovered
Kepler data has identified a star with a seven-planet system structured similarly to the sun’s clutch of planets.

Carbonation may have grounded Mars’ atmosphere
The chemical interaction could have forced Red Planet’s atmospheric carbon dioxide into the dirt.
