A study simulating the final stages of terrestrial planet formation shows that 'hit-and-run' encounters play a significant role in the acquisition of water by large protoplanets, like those that grew into Mars and Earth.

Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun.

An international team of astronomers have found that there are far more planets of the hot Jupiter type than expected in a cluster of stars called Messier 67.

Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper belt exhibit an unexpected clustering in their respective arguments of perihelion.

A detailed study of young stars and their surroundings has produced dramatic new evidence about how multiple-star systems form and how the dusty disks that are the raw material for planets grow around young stars.

A research group led by Anne Dutrey from the Laboratory of Astrophysics of Bordeaux, France, and the National Centre for Scientific Research (CNRS) observed the distribution of dust and gas in a binary star system called GG Tau-A.

Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006.

SpaceX successfully launched its upgraded Falcon 9 v1.1 rocket today on its maiden flight from the Vandenberg Air Force Base in what appeared to be a picture perfect launch.

Stars Can Be Late Parents

Using the unique capabilities of ESA's Herschel space observatory, astronomers have accurately 'weighed' a star's disc, finding it still has enough mass to spawn 50 Jupiter-sized planets, several million years after most other stars have already given birth.

New Theory on Earth and Moon Formation

New research, funded by the NASA Lunar Science Institute (NLSI), theorizes that our early Earth and moon were both created together in a giant collision of two planetary bodies that were each five times the size of Mars.

Planet Found in A Four-Star System

A joint effort of citizen scientists and professional astronomers has led to the first reported case of a planet orbiting twin suns that in turn is orbited by a second distant pair of stars.

Oscillations in the Habitable Zone around Alpha Centauri B

"The Alpha Centauri AB system is an attractive one for radial velocity observations to detect potential exoplanets. The high metallicity of both Alpha Centauri A and B suggest that they could have possessed circumstellar discs capable of forming planets. As the closest star system to the Sun, with well over a century of accurate astrometric measurements (and Alpha Centauri B exhibiting low chromospheric activity) high precision surveys of Alpha Centauri B's potential exoplanetary system are possible with relatively cheap instrumentation."
