NASA's GRAIL Creates Most Accurate Moon Gravity Map
Washington DC (SPX) Dec 06, 2012
Twin NASA probes orbiting Earth's moon have generated the highest resolution gravity field map of any celestial body. The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, is allowing scientists to learn about the moon's internal structure and composition in unprecedented detail. Data from the two washing machine-sized spacecraft also will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved. The gravity field ma ... read more

When the first stars blinked on As far back in time as astronomers have been able to see, the universe has had some trace of heavy elements, such as carbon and oxygen. These elements, originally churned from the explosion of massi ... more		Astronomers discover and 'weigh' infant solar system Astronomers have found the youngest still-forming solar system yet seen, an infant star surrounded by a swirling disk of dust and gas more than 450 light-years from Earth in the constellation Taurus ... more		New galaxy census highlights importance of starbursts Astronomers have used ESA's Herschel Space Observatory to identify thousands of previously undetected starburst galaxies - among the most prolific stellar factories in the Universe.
