[ Watch the Video: Sprites on Film ] April Flowers for redOrbit.com - Your Universe Online Fifty miles above the Earth, dancing high above the clouds during thunderstorms, a different kind of lightning flashes.  Bursts of red and blue light, known as sprites, flash for one thousandth of a second. Unless you happen to be looking directly at the flash, flying high over the clouds during a thunderstorm, you probably won't even see the sprite. One of the best places to get a good...

'CubeSat' will help solve mysteries of terrestrial gamma ray flashes, 1,000 times more powerful than 'northern lights' Imagine a fully-instrumented satellite the size of a half-gallon milk carton. Then imagine that milk carton whirling in space, catching never-before-seen glimpses of processes thought to be linked to lightning. The little satellite that could is a CubeSat called Firefly, and it's on a countdown to launch next year. CubeSats, named for the roughly four-inch-cubed...

Saturn Lightning Caught By Cassini
2012-07-19 07:52:38

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Cassini satellite, which has been visiting Saturn now for eight years, caught a rare daytime lightning strike in a massive storm that has been plaguing the northern hemisphere of the distant ringed-planet for most of 2011. The spacecraft caught the images on March 6, 2011 and marks the first time scientists have been able to detect lightning in visible wavelengths on Saturn´s illuminated surface (side facing the...

Number of flash floods and forest fires could increase with temperature, says TAU researcher Researchers are working to identify exactly how a changing climate will impact specific elements of weather, such as clouds, rainfall, and lightning. A Tel Aviv University researcher has predicted that for every one degree Celsius of warming, there will be approximately a 10 percent increase in lightning activity. This could have negative consequences in the form of flash floods, wild fires, or...

GIA announces the release of a comprehensive global report on Lightning Protection Technologies (LPT) markets. The global market for Lightning Protection Technologies is projected to reach US$1.05 billion by 2018, spurred by significant rise in number of lightning strikes, fatalities as well as mounting infrastructure losses in recent years. The urgent need to minimize huge loss of life and property underscores the importance of immediate and effective measures for installation and...

Lightning Safety Awareness Week
2012-06-26 06:33:07

redOrbit Meteorologist Joshua Kelly The week of June 24-June 30 is noted as “Lightning Safety Week”. So what are some things that you can do when you hear the first crackle of thunder? One of the first things to do is take cover inside a shelter such as a house, garage or even patio. The next thing you can do to help prevent injury is not run for cover under a tree or object outside that can easily be attracted to lightning. A third thing is try to avoid using appliances and...

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...
