Researchers hope to shed light on dark lightning radiation

Scientists now know that thunderstorms, working as powerful natural terrestrial particle accelerators, produce intense flashes of ionizing radiation called "dark lightning." To further their understanding of this phenomena, ...

Solar flares may disrupt GPS systems, researcher says

(Phys.org) —If your GPS navigation system goes on the fritz in the coming days, you might have the sun to blame. Early this week, the sun released four X-class solar flares, the strongest type of flare. Forecasters at the ...

Cassini sees Titan cooking up smog

(Phys.org)—A paper published this week using data from NASA's Cassini mission describes in more detail than ever before how aerosols in the highest part of the atmosphere are kick-started at Saturn's moon Titan. Scientists ...

Solar variability and terrestrial climate

(Phys.org)—In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of ...

ELISE investigating new type of heating for ITER

(Phys.org)—Tests for the heating that is to bring the plasma of the ITER international fusion test reactor to a temperature of many million degrees can go ahead from today: After three years of construction, Max Planck ...

CERN collider to become the world's fastest stopwatch?

Heavy ion collisions at CERN should be able to produce the shortest light pulses ever created. This was demonstrated by computer simulations at the Vienna University of Technology. The pulses are so short that they cannot ...

The science behind northern lights

(Phys.org)—Northern night skies have recently been alive with light. Those shimmering curtains get their start about 93 million miles away, on the sun.

NASA spacecraft records 'Earthsong'

Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.
