Two New Forms of Salt Water Could Rewrite Fundamental Chemistry

Two newly discovered forms of frozen salt water could help scientists resolve a mystery concerning the Solar System's ice-encrusted moons.

Jupiter Overtakes Saturn as The Planet With The Most Known Moons

Astronomers have counted 12 previously unknown moons in orbit around our Solar System's biggest planet, bringing the known total to 92, and leaving Saturn, with its measly count of 83, in the dust.

Saturn's Moon Titan Has Yet Another Strange Similarity to Earth

Compared to most places you might wander in the Solar System, Titan, the giant moon of Saturn, is in many ways strangely familiar to Earth.

Jupiter's Moon Europa Has Signs of Liquid Water

Strange double ridges on the surface of Jupiter's ice moon Europa could be signposts to shallow reservoirs of water. 

Europa Could Be Pulling Oxygen Down Below the Ice To Feed Life

Jupiter's moon Europa is a prime candidate in the search for life. The frozen moon has a subsurface ocean and the new research shows that the moon is pulling oxygen down below its icy shell.

The Best Evidence for Life on Mars Might be Found on its Moons

Some scientists think the best place to find evidence of life is one of Mars’ moons. They might serve as a depository for material that was blasted off of Mars’ surface in the past.

In a first, ALMA spies huge moon-forming disc around exoplanet

Astronomers using the Atacama Large Millimeter Array (ALMA) have spotted presence of a disc around a Jupiter-like exoplanet 400 light years away that could provide the raw material for up to three satellites the size of Earth’s Moon.

Titan's Largest Methane Sea is Over 100 Meters

Kraken Mare, a sea of liquid methane on Saturn's moon Titan, is at least 100-m deep near its center, according to a recent analysis of Cassini's data.

FM radio signal found coming from Jupiter moon

The Juno spacecraft orbiting Jupiter has discovered an FM radio signal coming from the moon Ganymede. The find is a first-time detection from the moon. The signal is of natural origin.

The Largest Sea On Titan Could Be Over 300 M Deep

A submarine mission to Saturn’s largest moon has long been under discussion. If such a mission was ever launched, it would have plenty of room to operate, because Titan’s largest sea, Kraken Mare, is likely more than 300 m deep.

Saturn's tilt caused by its moons

The current tilt of Saturn's rotation axis is caused by the migration of its satellites, and especially by that of its largest moon, Titan. Titan and the other moons are moving away from Saturn much faster than it had been previously estimated.

"Weird" Molecule Discovered in Titan's Atmosphere

NASA scientists identified a molecule in Titan’s atmosphere that has never been detected in any other atmosphere - cyclopropenylidene, or C3H2. This simple molecule may be a precursor to possible life on Titan.

Direct evidence of volcanic impact on Io's atmosphere

Previous research has shown that Io's atmosphere is dominated by sulfur dioxide gas. Now, astronomers could, for the first time, clearly see the plumes of sulfur dioxide (SO2) and sulfur monoxide (SO) rise up from the volcanoes.

Jupiter Probably Has 600 Small, Irregular Moons

In recent years, the confirmed number of Jovian moons has risen to 79. Now, a new study says that there may be 600 small irregular moons orbiting Jupiter.

Ganymede shows hints of Solar System's largest impact

Researchers have found what may be remnants of the solar system’s largest impact structure, ancient concentric troughs that extend across almost the entire surface of Jupiter’s moon Ganymede.
