How to look young when you're not - Stars reveal the secret of aging well
Dec 24, 2012 (ESA)
Some people are in great shape at the age of 90, while others are decrepit before they're 50. We know that how fast people age is only loosely linked to how old...
The paths of photons are random - but coordinated
Dec 24, 2012 (SPX)
Researchers at the Niels Bohr Institute have demonstrated that photons (light particles) emitted from light sources embedded in a complex and disordered structu...
Southampton researchers find a glitch' in pulsar 'glitch' theory
Dec 20, 2012 (SPX)
Researchers from the University of Southampton have called in to question a 40 year-old theory explaining the periodic speeding up or 'glitching' of pulsars. A ...
Astronomers identify the stellar patrons of the Milky Way bar
Dec 20, 2012 (SPX)

Experiment Examining a SLICE of the Interstellar Medium
Dec 19, 2012 (SPX)
When you look up at the stars at night, the space between stars looks empty. But, yes there is something there. It's called the interstellar medium. An experime...
Exploding star missing from formation of solar system
Dec 18, 2012 (SPX)
A new study published by University of Chicago researchers challenges the notion that the force of an exploding star forced the formation of the solar system. I...
Microquasar found in neighbor galaxy, tantalizing scientists
Dec 17, 2012 (SPX)
For the first time, astronomers have found a microquasar - a black hole devouring material from a companion star - in a galaxy beyond our own Milky Way. The obj...
24-armed Giant to Probe Early Lives of Galaxies
Dec 14, 2012 (SPX)
A powerful new instrument called KMOS has just been successfully tested on ESO's Very Large Telescope at the Paranal Observatory in Chile. KMOS is unique as it ...

Dec 14, 2012 (SPX)
Radio-astronomical observations of a distant galaxy indicate that the ratio of the proton's mass to that of the electron has hardly changed over cosmic history....
An Older Vega: New Insights About The Star All Others Are Measured By
Dec 13, 2012 (SPX)
Vega, a star astronomers have used as a touchstone to measure other stars' brightness for thousands of years, may be more than 200 million years older than prev...
Fermi Improves its Vision for Thunderstorm Gamma-Ray Flashes
Dec 12, 2012 (SPX)
