A team of scientists studied the hydrogen in water from the Martian interior and found that Mars formed from similar building blocks to that of Earth, but that there were differences in the later evolution of the two planets. This implies that terrestrial planets, including Earth, have similar water sources - chondritic meteorites.

The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from a team led by Carnegie's Stewart McWilliams studied how magnesium oxide behaves under the extreme conditions deep within planets and found evidence that alters our understanding of planetary evolution.

Astronomers have gotten a first look at the aftermath of Saturn's 'Great Springtime Storm' thanks to the heat-seeking capabilities of the international Cassini spacecraft and two ground-based telescopes. Even though the cosmic event is hidden to the naked eye, a giant oval vortex continues to exist long after the visible effects of the storm have subsided.

The search for a mysterious subatomic particle can certainly involve some enormous tools, not to mention a multitude of scientists. The effort to find the elusive "Higgs boson" includes over 5,800 scientists from 56 countries. It's a subatomic particle that gives other particles, such as quarks and electrons, their mass.

Outgassing - the physical process that creates that oh-so-alluring new car smell - isn't healthy for humans and, as it turns out, not particularly wholesome for sensitive satellite instruments, either. But a team of NASA engineers has created a new way to protect those instruments from its ill effects.

DARPA's ground-based Space Surveillance Telescope may soon head to Australia. An agreement reached this week with Australia's Department of Defense will allow DARPA to take the 180,000 lb. three-mirror Mersenne-Schmidt telescope to Australia to track and catalogues space debris and objects unique to the space above that region of the world that could threaten DoD satellites.

A discovery in the Andromeda constellation sheds new light on the birth of planets. The gas giant has roughly 13 times the mass of Jupiter, while the parent star has 2.5 times the mass of the Sun. This planet probably formed in a similar way to ordinary, lower-mass planets: in a 'protoplanetary disk' of gas and dust. This makes the planet an important test case for current models of how planets are born.

In space research, the Finnish Meteorological Institute specialises in large-scale computer simulations modelling the behaviour of particles and electromagnetic fields in the vicinity of Earth and other bodies in the solar system. Simulation models are used, for example, to study processes involved in the origin of auroras.

The American space program stands at the cusp of a "water rush" to the moon by several companies developing robotic prospectors for launch in the near future, according to a NASA scientist considering how to acquire and use water ice believed to be at the poles of the moon.

Near surface water has shaped the landscape of Mars. Areas of the planet's northern and southern hemispheres have alternately thawed and frozen in recent geologic history and comprise striking similarities to the landscape of Svalbard. This suggests that water has played a more extensive role than previously envisioned, and that environments capable of sustaining life could exist.
