Researchers Explore Dark Lightning
2013-04-11 10:57:42

April Flowers for redOrbit.com - Your Universe Online A group of researchers from Florida Institute of Technology's Department of Physics and Space Science recently asked the somewhat unusual question: "What are the radiation doses to airplane passengers from the intense bursts of gamma-rays that originate from thunderclouds?" Faculty members Joseph Dwyer, Ningyu Liu and Hamid Rassoul discussed the question and their answers concerning terrestrial gamma ray flashes at a press conference...

Like turning coal to diamond, adding pressure to an electrical material enhances its properties. Now, University of Illinois at Urbana-Champaign researchers have devised a method of making ferroelectric thin films with twice the strain, resulting in exceptional performance. Led by Lane Martin, a professor of materials science and engineering, the group published its results in the journal Advanced Materials. Ferroelectric materials, metal oxides with special polarization properties, are...

When talking about lightning, appearances of different lightning which occur along with thunderstorms will emerge in the minds of the people and these lightning occur in the troposphere. However, in addition to lightning in the troposphere, there are kinds of lightning discharges which occur above the thunderstorms. Up to now, lightning discharges above storms include sprite, elves (Emissions of Light and VLF perturbation due to EMP Sources, elves), Blue jet and Gigantic jet etc, and all of...

A new organic 'ferroelectric,' economical and with low environmental impact, has been created The electronics industry has a remarkable impact on the environment, yet research is devising new solutions to reduce it. Among these, a new compound with an unutterable name, the diisopropylammonium bromide (DIPAB), a new ferroelectric material created by an international team of researchers that include Massimo Capone and Gianluca Giovannetti of Istituto Officina dei Materiali at CNR and of the...

At the heart of computing are tiny crystals that transmit and store digital information´s ones and zeroes. Today these are hard and brittle materials. But cheap, flexible, nontoxic organic molecules may play a role in the future of hardware. A team led by the University of Washington in Seattle and the Southeast University in China discovered a molecule that shows promise as an organic alternative to today´s silicon-based semiconductors. The findings, published this week in the...

NORUSCA II Camera Examines Auroras
2012-11-29 19:36:55

Lee Rannals for redOrbit.com — Your Universe Online Space-weather researchers joined forces to design and build NORUSCA II in order to help expand the understanding of auroras and other atmospheric events. NORUSCA II is a new camera with the capabilities of simultaneously imaging multiple spectral bands. The camera was tested at the Kjell Henriksen Observatory (KHO) in Svalbard, Norway. The camera produced the first-ever hyper spectral images of auroras and may have already...

Scientist Claims To Have Theory On Mysterious Balls Of Lightning
2012-10-19 19:35:24

Lee Rannals for redOrbit.com — Your Universe Online CSIRO scientist John Lowke thinks he has the mysterious balls of lightning thing figured out, despite himself never witnessing one. Lowke has written a new scientific paper, and has also given the first mathematical solution explaining the birth of ball lightning and how it is capable of passing through glass. Documented sightings of ball lightning have been made across the world for centuries, but no explanation of how it...

Spotting Sprites

[ 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...

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 Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...

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...

Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
