Universe's quantum 'speed bumps' no obstacle for light
(Oct 29, 2009)
A hint that quantum fluctuations in the fabric of the universe slow the speed of light has not been borne out in observations by NASA's Fermi telescope. The measurements contradict a 2005 result that supported the idea that space and time are not smooth.

Multiplying universes: How many is the multiverse?
(Oct 29, 2009)
How many universes are there? Cosmologists Andrei Linde and Vitaly Vanchurin at Stanford University in California calculate that the number dwarfs the 10500 universes postulated in string theory, and raise the provocative notion that the answer may depend on the human brain.

Robot armada might scale new worlds
(Oct 29, 2009)
An armada of robots may one day fly above the mountain tops of Saturn's moon Titan, cross its vast dunes and sail in its liquid lakes. Wolfgang Fink, visiting associate in physics at the California Institute of Technology in Pasadena says we are on the brink of a great paradigm shift in planetary exploration, and the next round of robotic explorers will be nothing like what we see today.

Monster supernovae may explain galaxy's mystery haze
(Oct 28, 2009)
What is causing a mysterious "haze" of radiation at the center of the Milky Way? It may be a load of monster supernovae kicking out radiation which is then amplified by magnetic stellar winds and turbulence near the galaxy's core. The haze first came to light in 2003 when the Wilkinson Microwave Anisotropy Probe (WMAP) found a patch of particularly energetic microwave radiation in the center of our galaxy.

Asteroid blast reveals holes in Earth's defences
(Oct 27, 2009)
As the US government ponders a strategy to deal with threatening asteroids, a dramatic explosion over Indonesia has underscored how blind we still are to hurtling space rocks. On 8 October an asteroid detonated high in the atmosphere above South Sulawesi, Indonesia, releasing about as much energy as 50,000 tons of TNT, according to a NASA estimate released on Friday. That's about three times more powerful than the atomic bomb that levelled Hiroshima.

Meet Peristera, the 'female pigeon' exoplanet
(Oct 26, 2009)
The profusion of planets discovered around other stars in the past 15 years has led to a naming problem. Most of these exoplanets are known only by drab scientific designations like MOA-2007-BLG-400-L b. Unsatisfied with this situation, Wladimir Lyra, an expert on planet formation, has proposed new names for all 400 of them.

Laser microscope aims to uncover alien life
(Oct 23, 2009)
Microscopes revolutionized the study of life on Earth. Now a rugged, easy-to-use instrument is aiming to be equally influential in the search for alien life in locations such as the oceans beneath the icy surface of Jupiter's moon Europa. Called the digital inline holographic microscope, it consists of a pair of watertight compartments separated by a chamber into which water can flow.

Astronomers find organic molecules around second gas giant
(Oct 22, 2009)
Peering far beyond our solar system, NASA researchers have detected the basic chemistry for life in a second hot gas planet, HD 209458b, advancing astronomers toward the goal of being able to characterize planets where life could exist. The planet is not habitable but it has the same chemistry that, if found around a rocky planet in the future, could indicate the presence of life.

To spot an alien, follow the pollution trail
(Oct 19, 2009)
Do aliens pollute their planets? Let's hope they do, as this would give us a promising way of spotting where they live. Observed over interstellar distances, theylight from our cities would reveal to the observer the presence of a technology, says a team of astronomers led by Jean Schneider of the Paris Observatory at Meudon, France. In a paper to appear in Astrobiology, the team suggests we should look for a similar glow on alien planets.
