NASA THEMIS satellites change solar storm theory

The THEMIS discovery changes how scientists think about charged solar particles (plasma) from the Sun interacting with the magnetic field (magnetosphere) of the Earth. They can now more accurately measure the amount of energy released, which causes magnetic storms and intensifies auroras.

Moon magnetic discovery shows how much we don't know

MIT astronomers have discovered that a lunar liquid core, which existed about 4.2 billion years ago, generated the Moon’s current magnetic field. Concerning why we should go back to the Moon, one of the MIT scientists said we have literally "only scratched the surface."

'Star Trek' force field could help protect real astronauts in space

British, Portuguese, and Swedish physicists have come up with a strong magnetic shield that may be able to protect astronauts from dangerous space radiation as they make extended missions to the Moon, Mars, and beyond. Better get Scotty to engineer the project!

Scientist takes a spin at better computer hard drives

A Japanese researcher is experimenting with a way to manipulate the spin of electrons in magnetized solids so as to eventually make computer memory devices that produce much less heat than conventional ones.

Cows and deer head north, literally

German and Czech researchers studied satellites images of thousands of cows and deer around the world and found most of them graze and rest in a north-south position. Could they be sensing the magnetic field of the Earth? Or, maybe they just happened to stand and sit that way? In any case, it’s a pretty mooooving study!

NASA determines what puts the "dance" into Northern Lights

According to the July 24, 2008 news release, NASA confirms that the THEMIS spacecraft have found that stressed out magnetic field lines are causing the colorful lights shows of the Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) here on Earth.

Our MESSENGER to Mercury sends home important data

The NASA spacecraft MESSENGER flew by Mercury on January 14, 2008. It reported back to scientists on Earth some information they did not know about its volcanic history and the source of its magnetic field.

Wolves howl at Full Moon: Guess what happens On The Moon?

NASA scientists have discovered that the tail of the Earth’s magnetic field goes out to the Moon when it is full. This interplay between Earth’s magnetotail and the Full Moon has been found to cause lunar dust storms and electrostatic discharges (static).

Racetrack memory promises major storage expansion for devices

New non-volatile memory technologies pop up from time to time, but they don't always make a lasting impression. Remember bubble memory? What about FRAM? Now IBM reckons its 'racetrack' memory could deliver the performance and reliability of flash memory with the low cost and high capacity of hard drives.

U.S. astronomers see first magnetic reversal of star other than Sun

Astronomers have found the first evidence of a star changing its magnetic field. The Sun is known to reverse its north and south magnetic poles, but astronomers had never seen another star do it. Now they have seen it in tau Bootis.
