Gravity mission on track to map Earth's shifty mass
Six months into its mission to precisely measure Earth's shifting water masses and map their effects on Earth's gravity field, the joint NASA-German Aerospace Center Gravity Recovery and Climate Experiment, or Grace, is already producing results of considerable interest.

From satellites to sea: JPL scientists map ocean eddies
Just as sunlight glints off the ocean's surface, so do radio signals from the constellation of global positioning system navigation satellites orbiting Earth. Now, researchers from NASA's Jet Propulsion Laboratory have shown that although these reflected signals are very weak, they can be detected by airborne instruments and used to map ocean eddies.

Surprising black hole activity in old galaxies
Scientists at the Carnegie Observatories have uncovered six times the expected number of active, supermassive black holes in a single viewing of a cluster of galaxies, a finding that has profound implications for theories as to how old galaxies fuel the growth of their central black holes.

Rare class of exotic stars revealed as super-magnets
Scientists have found that a rare and enigmatic class of neutron stars, of which only five are known, are actually magnetars -- exotic stars with magnetic fields trillions of times stronger than the Sun's or Earth's, so powerful that they could strip a credit card clean 100,000 miles away.

A rose blooming in space
Resembling a delicate rose floating in space, the nebula N11A is seen in a new light in a true-colour image taken by the NASA/ESA Hubble Space Telescope. Fierce radiation from massive stars embedded at the centre of N11A illuminates the surrounding gas with a soft fluorescent glow.

Indian weather satellite launched into space
A PSLV rocket lifted off Thursday from the Sriharikota launch base in India carrying the METSAT weather satellite. The four-stage vehicle injected the spacecraft into geosynchronous transfer orbit. METSAT is India's first satellite totally dedicated to weather observing. Previous satellites were combo platforms for meteorology and telecommunications.

Newly found object could be old Apollo rocket stage
An analysis of the orbital motion of the newly discovered object J002E3 indicates that it could be a leftover Saturn 5 third stage from one of the Apollo missions, most likely Apollo 12, launched on November 14, 1969.

ESA to look for the missing link in gravity
Although you can never be certain of predicting future developments in science, there is a good chance of a fundamental breakthrough in physics soon. With a series of unique experiments and missions designed to test our understanding of gravity, the European Space Agency hopes to get to the very bottom of it.

Satellite data could track terrorist threats
Orbiting 500 miles above the planet, satellites give scientists a "big picture" view of changes to the Earth's landscape -- from suburbanization trends to shoreline erosion. Now, an Ohio University researcher is using the technology to try to detect a more dangerous activity: terrorism and the areas of the country most vulnerable to potential attacks.

Research reveals new Kuiper Belt satellite mystery
The Kuiper Belt region of the solar system, which stretches from just past Neptune to beyond the farthest reaches of Pluto's orbit, was only discovered in 1992, but continues to reveal new knowledge into the formation processes of the planets. Now, in a paper to be published in the October issue of The Astronomical Journal, a scientist reveals a new mystery about Kuiper Belt Objects.
