Wanna see the space station overhead? NASA will send you mail!

Seeing the International Space Station pass overhead is pretty cool. It glides soundlessly across the sky, getting brighter as it gets closer to you, whizzing by hundreds of kilometers above your head at 8 kilometers per second.

I usually go to Heavens-Above when I think of it to check when the next few passes will be. But wouldn't it be nice if you get a text or email letting you know that a pass is about to happen?

X-ray source for imaging system developed to produce 'molecular movies'

One of the most urgently sought-after goals in modern science is the ability to observe the detailed dynamics of chemical reactions as they happen – that is, on the spatial scale of molecules, atoms, and electrons, and on the time scale of picoseconds or even shorter.

Thermal processes involved in heat-assisted magnetic recording paves the way for commercial devices

Most electronic data is stored on magnetic hard drives that spin at many thousands of revolutions per minute. To keep pace with ever-growing storage demand, however, achieving greater storage capacities by simply increasing the size of disks is infeasible. The required spinning speed would put immense physical strain on the components, particularly on the writing 'head'—a small needle-like object used to write data at particular points on the disk.

Physicists propose a way to make atomic clocks more accurate

(Phys.org)—Physicists Andrei Derevianko of the University of Nevada and Victor Flambaum and Vladimir Dzuba of the University of New South Wales have proposed in a paper published in Physical Review Letters a way to improve on the accuracy of atomic clocks. They suggest stripping away electrons from ions to reduce the negative effects of stray fields that reduce the performance of current atomic clocks.

NASA Astronaut to Discuss His Residency in Space

NASA astronaut Don Pettit, a veteran of three spaceflights, will discuss life and science aboard the International Space Station at the Arizona Science and Astronomy Expo Saturday, Nov. 10.

Keeping The Wheels Turning: Registration Open For 20th Annual NASA Great Moonbuggy Race

Registration is now open for the 20th annual NASA Great Moonbuggy Race, which challenges high school, college and university students around the world to build and race fast, lightweight "moonbuggies" of their own design.

NASA Ceremony to Rename Twin Earth Radiation Belt Spacecraft

Media representatives are invited to attend a ceremony to announce the renaming of NASA's Radiation Belt Storm Probes (RBSP).

NASA Holds Innovative Advanced Concepts Symposium Nov. 14-15

The NASA Innovative Advanced Concepts (NIAC) Program's 2012 Fall Symposium will be held Nov. 14-15, 2012 at the Crowne Plaza Hotel in Hampton, Va.

Scientists Detect 12-Billion-Year-Old Supernova, the Oldest Yet Observed

The most recently observed stellar explosion in our neighborhood
was Kepler's supernova, spotted 400 years ago.
Scientists using a telescope atop a Hawaiian volcano have detected a pair of extra-bright supernovae, or star explosions, one of which is the oldest, most-distant supernova ever detected.
