Image 1 - Lightning-Made Waves Leaking Into Space From Earth's Atmosphere

[ Watch the Video ] NASA said on Monday that scientists have discovered lightning-made waves in Earth's atmosphere that leaked into space. The space agency's Vector Electric Field Instrument (VEFI) aboard the U.S. Air Force's Communications/Navigation Outage Forecast System (C/NOFS) satellite has detected Schumann resonance from space. Schumann resonance happens if waves are just the right wavelength from lightning, combining and increasing in strength to create a repeating...

Lightning Sprites Are Out-of-This-World

TAU researchers predict "sprites" in the atmospheres of Jupiter, Saturn, and Venus Only a few decades ago, scientists discovered the existence of "sprites" 30 to 55 miles above the surface of the Earth. They're offshoots of electric discharges caused by lightning storms, and a valuable window into the composition of our atmosphere. Now researchers at Tel Aviv University say that sprites are not a phenomenon specific to our planet. Jupiter and Saturn experience lightning storms with...

Researchers Create Extra-long Electrical Arcs Using Less Energy
2011-11-09 09:10:28

Researchers at the University of Canterbury, in New Zealand, have developed a new, lower-voltage method of generating extra-long, lightning-like electrical arcs. The arcs are created when an electrical impulse is applied to a thin copper wire that subsequently explodes. By jump-starting the arcs using exploding wires, as opposed to the traditional method of directly breaking down air, the researchers reduced the amount of voltage needed to create an arc of a given length by more than 95...

[ Video 1 ] | [ Video 2 ] Part of human fascination with space is the chance to look back at our own planet from afar. The unique vantage from the International Space Station affords a vista both breathtaking and scientifically illuminating. Here on Earth, both scientists and spectators rely on the station's crew to record and transmit images and videos of what they see to share in their experience. Until recently, reduced lighting conditions at night, combined with insufficiently...

Firestation In Space To Open Firehose Of Lightning Data

When opportunity knocked, NASA heliophysicist Doug Rowland answered. He and his team recently secured another flight opportunity for a pint-sized instrument studying lightning in Earth's upper atmosphere and now are bracing for a veritable "fire hose" of data about a little-understood phenomenon first discovered by scientists nearly two decades ago. The instrument, Firestation, is one of four experiments manifested to fly on an experiment pallet the U.S. Department of Defense plans to...

PENDLETON, Ind., Aug. 16, 2011 /PRNewswire/ -- Using a Remy propulsion electric motor, Lightning Motorcycles, LLC. blasts through the land speed record for production electric bikes by 30mph to be crowned the first electric bike in the world to exceed 200mph. In an August 14 SCTA*-sanctioned run at the Bonneville Salt Flats in Utah, Lightning -- the 2010 land speed record holder -- achieved 206.079 mph, topping its 2010 speed of 176mph. Lightning retains its claim as the fastest electric...

When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and enters the clear air of the sky. A third type of lightning is the cloud to ground. This is the most...

A lightning rod is a metal conductor mounted on the top of a building and connected through a wire to the ground to protect the building from lightning. The rod should conduct the electricity from a lightning strike down through the wire instead of passing through the building. The rod is just a single component in the lightning protections system along with rooftop conductors and multiple conductive paths. Benjamin Franklin invented the lightning rod in 1749. The taller the building the...

Heat Lightning is actually faint flashes of lightning reflecting outward from distant thunderstorms. These flashes usually do not produce thunder as the storm is sometimes too far away to be heard. The term heat lightning got its name because it often occurs on hot summer nights and does not produce audible thunder. One reason heat lightning can be seen so far away is due to the reflection of the light bouncing off water particles in moist, humid air and as light is scattered throughout the...
