Slashed across the south pole of Saturn's moon Enceladus are four straight, parallel fissures or 'tiger stripes' from which water erupts. These fissures aren't quite like anything else in the Solar System. Researchers now think they have a model to explain them.

Early returns from the US Naval Research Laboratory's camera on NASA's latest mission to study the Sun's corona revealed on Dec. 4 a star more complex than ever imagined.

The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its evaporating atmosphere.

Scientists studying the weather and climate of Titan, Saturn's largest moon, have reported a significant seasonal variation in its energy budget, a finding which could yield new insights into climate on Earth.

Measurements taken by the Solar Wind Around Pluto (SWAP) instrument aboard NASA's New Horizons spacecraft are providing important new insights from some of the farthest reaches of space ever explored. Astronomers now show how the solar wind -- the supersonic stream of charged particles blown out by the Sun -- evolves at increasing distances from the Sun.

There's new hope that we aren't alone in the universe, that advanced beings may exist on exoplanets. But they're probably not close by, says a new study on the stability of planetary tilts -- and orbits -- needed to encourage the evolution of complex life.

Scientists leveraged LISA Pathfinder's record-setting sensitivity (designed to ripples in space-time produced by, among other things, merging black holes) for a different purpose much closer to home -- mapping microscopic dust shed by comets and asteroids.

Even by the wild standards of the outer solar system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to newly published research.

An astrophysicist has discovered many new multiple star systems that contain exoplanets. For this, he searched more than 1,300 exoplanet host stars. He found that 15 per cent of those stars have at least one companion star, which is only about half the frequency expected for solar like stars. This could indicate that the influence of several stars in a system disrupts the process of planet formation.

For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars.
