Lifetime of gravity measurements heralds new beginning
Paris (ESA) Aug 01, 2014
Although ESA's GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn together to offer new opportunities for science. Carrying the first 3D gravity sensor in space, this state-of-the-art satellite measured Earth's gravity with unprecedented accuracy. GOCE's four years in orbit resulted in a series of four gravity models, each more accurate than the last. T ... read more

Young binary star system may form planets with weird and wild orbits Unlike our solitary Sun, most stars form in binary pairs - two stars that orbit a common center of mass. Though remarkably plentiful, binaries pose a number of questions, including how and where pl ... more		Tidal forces gave moon its shape The shape of the moon deviates from a simple sphere in ways that scientists have struggled to explain. A new study by researchers at UC Santa Cruz shows that most of the moon's overall shape can be ... more		Mercury's magnetic field tells scientists how its interior is different from Earth's Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicis ... more
