The Arecibo Observatory telescope, the largest and most sensitive single dish radio telescope in the world, is about to get a good deal more sensitive

Today (Wednesday, April 21) the telescope got a new “eye on the sky” that will turn the huge dish, operated by Cornell University for the National Science Foundation, into the equivalent of a seven-pixel radio camera.

The complex new addition to the Arecibo telescope was hauled 150 meters (492 feet) above the telescope’s

If a University of California, Berkeley, physicist’s vision of Jupiter is correct, the giant planet will be in for a major global temperature shift over the next decade as most of its large vortices disappear.

But fans of the Great Red Spot can rest easy. The most famous of Jupiter’s vortices – which are often compared to Earth’s hurricanes – will stay put, largely because of its location near the planet’s equator, says Philip Marcus, a professor at UC Berkeley’s De

Scientists have found that the way spiders stick to ceilings could be the key to making Post-it® notes that don’t fall off – even when they are wet. A team from Germany and Switzerland have made the first detailed examinations of a jumping spider’s ‘foot’ and have discovered that a molecular force sticks the spider to almost anything. The force is so strong that these spiders could carry over 170 times their own body weight while standing on the ceiling. The research is published today (Monday 19 Apr

Berkeley Lab physicists develop way to digitally restore and preserve
audio recordings
The 1995 discovery of the top quark and singer Marian Anderson’s 1947 rendition of Nobody Knows the Trouble I’ve Seen may seem unrelated. But through an interagency agreement with the Library of Congress, the same technology used to study subatomic particles is helping to restore and preserve the sounds of yesteryear.

“We developed a way to image the grooves in a recording that is simil

Distant star reveals planet Like Sherlock Holmes holding a magnifying glass to unveil hidden clues, modern day astronomers used cosmic magnifying effects to reveal a planet orbiting a distant star. This marks the first discovery of a planet around a star beyond Earth’s solar system using gravitational microlensing. A star or planet can act as a cosmic lens to magnify and brighten a more distant star lined up behind it. The gravitational field of the foreground star bends

VLT looks through narrow atmospheric window and produces most detailed images yet New images of unsurpassed clarity have been obtained with the ESO Very Large Telescope (VLT) of formations on the surface of Titan, the largest moon in the Saturnian system. They were made by an international research team [1] during recent commissioning observations with the “Simultaneous Differential Imager (SDI)”, a novel optical device, just installed at the NACO Adaptive Optics instrument [2].
