The biggest storm in the Solar System has attracted a lot of attention over the years, but the extreme complexity of the storm system has only just recently come to light through intense study by the Very Large Telescope in Chile and the Subaru Telescope in Hawaii. They show that despite continuous upheaval the Spot is remarkably stable.

At 1.3 million cubic feet, the Goddard Space Flight Center’s High Bay Clean Room, where the components of the James Webb Space Telescope are now being assembled, circulates a staggering one million cubic feet of air per minutes, ensuring no more than 10,000 particles larger than 0.5 microns. Progress on the telescope can now be viewed by webcam.

An analysis of more than 70,000 galaxies by physicists in the U.S. and Switzerland demonstrates that the universe—at least up to a distance of 3.5 billion light years from Earth—plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity.

Though comets are thought to be some of the oldest, most primitive bodies in the solar system, new research on comet Wild 2 (including this TEM image of its material) indicates that inner solar system material was transported to the comet-forming region at least 1.7 million years after the formation of the oldest solar system solids.

A worldwide team of researchers have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe. The full antinucleus—an antiproton, antineutron, and anti-Lambda particle—is the first to contain an anti-strange quark and represents the first nucleus to drop below the plane in the 3-D Periodic Table of Elements.

Astronomers from the United States and Europe have used a gravitational lens—a distant, light-bending clump of dark matter—to make a new estimate of the Hubble constant, which determines the size and age of the universe.

Jets of particles streaming from black holes in far-away galaxies operate differently than previously thought, according to a study published recently in Nature. A new study reveals that most of the jet's light—gamma rays, the universe's most energetic form of light—is created much farther from the black hole than expected and suggests a more complex shape for the jet.

Over the next three years, Southwest Research Institute scientists will develop and fly microgravity and space astronomy experiments on multiple suborbital space flights. The project marks a new approach to low-orbit astronomy experiments, conducted “in the field”.

In the short time that the image of Fomalhaut—a star with a Jupiter-sized planet imaged by Hubble Space Telescope—was published by UC Berkeley’s Paul Kalas, it has become an icon. Why? The 2008 image was the first visible-light picture of an extrasolar planet.

Physics software simulates parameters for extracting water from the Moon. Preliminary data from NASA’s Lunar CRater Observing and Sensing Satellite (LCROSS) indicates that the mission successfully uncovered water during the Oct. 9, 2009, impacts into the Moon’s south pole.
