Early volcanic activity may have caused bumps to erupt across lunar plains

Scientists have discovered a new feature on the surface of the Moon: small mounds that grew on its dark plains, likely from volcanic activity.

Discovery of boron on Mars adds to evidence for habitability

The discovery of boron on Mars gives scientists more clues about whether life could have ever existed on the planet, according to a paper published today in Geophysical Research Letters, a journal of the American Geophysical Union.

Moon’s tidal stress likely responsible for causing deep moonquakes, new study confirms

The same gravitational force responsible for creating tides on Earth could be causing deep quakes on the moon, a new study confirms.

A new analysis of data gathered by the Apollo missions confirms that tidal stress – the gravitational pull of the moon on the Earth and of the Earth on the moon – is responsible for causing deep moonquakes, the lunar equivalent of earthquakes.

Elevated zinc and germanium levels bolster evidence for habitable environments on Mars

New data gathered by the Mars Curiosity rover indicates a potential history of hydrothermal activity at Gale Crater on the red planet, broadening the variety of habitable conditions once present there, scientists report in a new study. Researchers found concentrations of the elements zinc and germanium to be 10 to 100 times greater in sedimentary rocks in Gale Crater compared to the typical Martian crust.

Early Tanpopo mission results show microbes can survive in space

Clumps of microbes can survive in space for at least a year – and perhaps longer, according to Japanese researchers conducting an experiment on board the International Space Station (ISS).

Mercury’s craters offer clues to planet’s contraction

Craters serve as time-markers for the faults because they can be dated by how degraded they appear. The more degraded looking craters are older. Those that have sharper features are younger, and those with bright rays of debris radiating around them are youngest of all.

Ice in Ceres’ shadowed craters linked to tilt history

Researchers from NASA’s Dawn mission find that the axial tilt of Ceres — the angle at which it spins as it journeys around the sun — varies widely over the course of about 24,500 years. Astronomers consider this to be a surprisingly short period of time for such dramatic deviations.

Random temperature fluctuations may have made Earth habitable

Random temperature fluctuations in the mantle and on the planet’s surface could be the reason Earth is a habitable world with moving tectonic plates while other terrestrial planets in the solar system are inhospitable worlds, according to new research.

Rare molecule on Venus could shed light on planet’s weather

Scientists’ keen detective work may have solved one of Venus’s oldest secrets: why the planet’s atmosphere absorbs ultraviolet light of a specific frequency. The new findings could help scientists better understand Venus’s thick atmosphere and its heat-trapping clouds, according to the study’s authors.

Research suggests Saturn’s moon Dione may harbor a subsurface ocean

A subsurface ocean could lie deep within Saturn’s moon Dione, according to a new study using publicly available data from the Cassini mission to Saturn. In 2013, images from NASA’s Cassini spacecraft hinted that Dione had a subsurface ocean when the moon formed, but the new study suggests the ocean could still exist today.
