A powerful lightning storm in Saturn's atmosphere that began in mid-January 2009 has become the Solar System's longest continuously observed thunderstorm.  It broke the record duration of 7.5 months set by another thunderstorm observed on Saturn by NASA's Cassini spacecraft between November 2007 and July 2008. The observations of the thunderstorm will be presented by Dr Georg Fischer of the Austrian Academy of Sciences at the European Planetary Science Congress in Potsdam, Germany, on...

A freak bolt of lightning struck a 56-year-old cyclist in Englewood, Colo., even though no electrical storms were reported in the area, authorities say. Perry Schellpfeffer, an Englewood police spokesman, told The Denver Post the unidentified victim was hit by the lightning Wednesday afternoon. His injuries were not considered life-threatening. There were some clouds and it was thundering a little, but there wasn't any kind of lightning storm, Schellpfeffer said. Among U.S. states, Colorado...

GENEVA, August 31 /PRNewswire/ -- The dataset will provide lightning information throughout the globe to serve the world's meteorological institutions and other weather-dependent users. Consisting of lightning sensors distributed throughout the globe, the coverage and performance of Vaisala's Global Lightning Dataset (GLD360) is unique, global, and real-time. GLD360 outperforms satellite lightning detection by enabling uniform global coverage and by providing the timeliest...

U.S. scientists say they've captured a one-second image and the electrical fingerprint of a gigantic lightning jet that flowed 40 miles upward from a storm. While not occurring every time a thunderstorm develops, the rarely seen, highly charged meteorological events can flash up to the lower levels of space, or the ionosphere, Duke University scientists said. They are substantially larger than their downward striking cousins. Despite poor viewing conditions as a result of a full moon and a...

Duke University researchers have captured images of lightning bolts shooting upwards. The rare phenomenon, known as "gigantic jets," was photographed during tropical storm Cristobal last year. The gigantic jets shot more than 40 miles high, Duke Professor Steven Cummer and colleagues wrote in the journal Nature Geoscience. "Despite poor viewing conditions as a result of a full moon and a hazy atmosphere, we were able to clearly capture the gigantic jet," said Cummer. "What we were able to...

Utilizing fractal patterns similar to those created by lightning strikes, Victor Ugaz, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, has created a network of microchannels that could advance the field of tissue engineering by serving as a three-dimensional vasculature for the support of larger tissue constructs, such as human organs.Ugaz's work, which was undertaken with colleague Arul Jayaraman and appears in the July online version...

A 38-year-old bricklayer in the British town of Kettering says he is lucky to have survived being struck by lightning while walking his dogs. The Daily Mail Monday said Brad Gifford was hit by a 300,000-volt bolt of lightning while attempting to seek shelter from a thunderstorm by ducking under a tree. Gifford suffered burns to 11 percent of his body and both of his eardrums were burst. Nonetheless, he expressed relief at having survived the potentially deadly lightning strike, the newspaper...

A Florida woman said she, her 4-year-old son and a 17-year-old friend were uninjured when a bolt of lightning crashed through her car. Michelle St. Val, 23, said she was driving Friday evening on Interstate 595 toward the airport in Fort Lauderdale to pick up her brother when her car lit up like it was Christmas, the South Florida Sun-Sentinel reported Monday. It was a huge boom, and then lightning completely took over the car, she said. St. Val said the 2003 Chevrolet Impala lost power and...

Experts say 2009 already has been proved a dangerous year for lightning strikes in the United States and warn the worst may be yet to come. National Weather Service lightning expert John Jensenius said 11 people have been killed in the United States by lighning strikes just this month as the particularly dangerous summer months get under way, ABC News reported Monday. Last year was an exceptionally good year for not having fatalities. This year is starting out as an exceptionally bad year,...

Most people know to unplug computers to prevent lightning damage but some are injured by lightning using hardwired video games, a U.S. researcher says. Dr. Mary Ann Cooper, director of the lightning injury research program at the University of Illinois at Chicago, notes an increasing number of people injured indoors using Play Stations and other such video games. Cell phones, iPods and other wireless devices do not attract lightning but they may distract people from paying attention to the...

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
