Lab experiment mimics early-stage planetary formation process
Physicists have directly observed, for the first time, how highly charged dust-sized particles attract and capture others to build up clusters particle by particle. This process can lead to the formation of "granular molecules" whose configurations resemble those of simple chemical molecules.

Cassiopeia's hidden gem: The closest rocky, transiting planet
A star in the constellation Cassiopeia has a planet in a three-day orbit that transits, or crosses in front of its star. At a distance of just 21 light-years, it is by far the closest transiting planet to Earth, which makes it ideal for follow-up studies. Moreover, it is the nearest rocky planet confirmed outside our solar system.

Scientists study ‘peanut-shaped’ asteroid near earth
A mile-long asteroid that raced past Earth July 25 at about 45,000 miles per hour – at a safe distance of 4.5 million miles – was imaged by radar telescopes so that astronomers could discern its precise orbit and physical shape.

An orange a day keeps scurvy away
Centuries ago, ships often sailed with crews numbering in the hundreds returning with tens. Cause of death: Scurvy - a severe depletion of Vitamin C. Today's explorers cross miles of space with no hope of finding an island with food and nutrients along the way. All nutritional needs must be met aboard.
