Flashes. 12 Oct A bright star twinkling with red and green flashes, low in the northeastern sky on October evenings, is probably Capella. So that's where Capella's red and green flashes are coming from not from the star itself but from the refraction of its light by our atmosphere. When you see Capella higher in the.
From St Elmo's fire to sprites and blue jets, discover the peculiar glowing balls and streaks that form in Earth's atmosphere. Sailors out at sea would sometimes see a bluish glow seeming to shoot out of the ends of the masts of ships at night. The light wasn't hot and wouldn't burn anything on board. They took it to be a good omen and called it St Elmo's fire.
A sunspot usually consists of a circular dark core the umbra with a vertical magnetic field and radially-elongated fine threads the penumbra with a horizontal field. But it couldn't say for sure what it was, it said. Researchers do know that there is another phenomenon called a gigantic jet, which seems to be a hybrid of a blue jet and a sprite. Drought forces Mozambique capital to ration water Maputo AFP Feb 14, Mozambique authorities on Wednesday introduced water rationing to more than a million residents in the capital Maputo due to a severe drought.
Ackerman's brother was working on some copper piping in his basement during some bad weather. Thunderclouds create a strong electric field, because there is a strong difference in electrical charge between the cloud and the ground, which you can sometimes feel as static. The field can be intensified by pointed objects, like a metal pipe or the mast of a ship.
If this electrical field becomes strong enough, it can break air molecules down into electrically-charged particles. The gases become "plasma", and give off a glowing light. A similar plasma glow can be created in the laboratory, using sharp or pointed objects to intensify an electrical field. Even so, Ackerman wants to see St Elmo's fire naturally. View image of A 19th-century engraving click at this page a will-o'-the-wisp Credit: Like St Elmo's fire, the will-o'-the-wisp is a faint light that has been reported for centuries.
But unlike St Elmo's fire, in recent times people have reported it less and less. As you might expect of a phenomenon whose name has come to mean something elusive, it has never been created in the laboratory. The will-o'-the-wisp is normally described as a light, flickering or constant, lying close to the ground, mostly in marshy areas of the countryside.
It supposedly disappears after a couple of minutes. Luigi Garlaschelli of the University of Pavia in Italy — best-known for recreating the Turin shroud with a few laboratory tricks — would like to study the will-o'-the-wisp in nature. But Flashes Of Light In The Sky Tonight is not clear there is anything to study.

If will-o'-the-wisp really did represent a natural process, there are some possible explanations that Garlaschelli could test. For example, the association with marshy areas suggests that the light comes from burning marsh Flashes Of Light In The Sky Tonight, which is mainly methane. However it is not clear what would set the gas alight. Alternatively, it could be that the reports are fictitious; that the lights are imagined or hallucinated; or that the lights were reflections of the Moon or other lights that observers misinterpreted.
But it doesn't burn anything. You might feel a bit funny, but you wouldn't be harmed. The shock waves were racing through, and as the later waves arrived there was an explosion of lights. These lights are a plasma discharge that happens when Flashes Of Light In The Sky Tonight particular type of rock is under stress and builds up an electric charge, Freund says.
Coseismic earthquake lights, which happen during an earthquake, are bursts of light coming out of the ground over a space of a few kilometres. They rise m into the night sky in a fraction of a second, one after another. In recent years, the abundancy of security cameras has led to beautiful videos of earthquake lights. View image of Ball lightning was once apocryphal Credit: When an http://hnusta.info/moq/signs-that-pisces-man-likes-you.php cloud-to-ground lightning bolt strikes the ground, it can vaporise certain minerals in the soil.
In a team of researchers were measuring ordinary lightning in a storm-prone region of the Qinghai Plateau in China. Suddenly a ball of light about 5m across appeared in front of them. It burned white and then red for a few seconds before vanishing. This was the first natural ball lightning to be studied. The researchers recorded the spectrum of light that the ball gave off, and analysed it to see if they could determine what this unusual lightning was made of.
It turned out to have a very earthly origin: Some of these contain silicon compounds, and under see more extreme conditions they undergo chemical reactions to form silicon filaments.
These filaments are highly reactive, and burn with the oxygen in the air to create the orange glow that the researchers measured. View image of The green flash as the Sun sets Credit: In the very last seconds before the Sun sets, its light can turn bright green. But the Sun has not changed colour: The atmosphere splits the Sun's white light into its separate colours, just like a prism: Because red undergoes the strongest bending effect, it appears to fall past the horizon first, followed by orange, yellow and green.
The colours beyond green — blue, indigo, and violet — are strongly scattered by the gases in the atmosphere. That's why the sky appears blue. But as a result, the last coloured light that can be seen as the Sun falls below the horizon is green. Normally this effect is very slight. To make the last green rays visible, there also has to be a mirage that makes the Sun appear much larger than usual.
These are the Flashes Of Light In The Sky Tonight that can make the Sun seem to move in shimmering waves, and almost seem liquid as it pours past the horizon. View image of This video is no longer available. Lightning was travelling not from cloud to ground, but shooting up from buildings into storm clouds. Meteorologists now know around one in a thousand lightning bolts strike upward.
But despite decades of research on upward lightning, its exact mechanism is still a puzzle. His and others' research has shown that there are two distinct forms of upward lightning. Both of them require a tall structure, such as a skyscraper or wind turbine, to happen. The first kind requires a link ordinary cloud-to-ground strike first. The sudden disruption to the electric field causes a "lightning leader", a channel of positive or negative charge, to travel up to an area of thundercloud with the opposite charge.
The second kind doesn't require a downward lightning strike nearby, and can travel upward spontaneously.

Warner has studied and photographed these rare events since becoming fascinated by an upward lightning bolt in To get his data and images, he has piloted an armour-plated plane into the hearts of storms.
Every time I flew through a thunderstorm, I reaffirmed that it was no http://hnusta.info/moq/do-you-have-to-pay-for-plenty-of-fish.php for a plane. View image of The first colour photo of a sprite, 4 July Credit: High above a thundercloud and its exchange of lightning with the ground, you might find a sudden reddish glow stretching for tens to hundreds of kilometres.
It looks a bit like the straggling tendrils of a jellyfish. Very large thunderstorms can produce these phenomena, which are known as sprites. Maybe only one in a thousand flashes produces a sprite.

These flashes need to remove a lot of electrons from the thundercloud. A long, slow current is needed to make a sprite, and such currents can form in big storm systems reaching km across. The elusiveness of these deep red flashes earned them their ethereal name, adopted from Shakespeare's A Midsummer Night's Dream.
But as the price of powerful cameras has dropped, sprites are being caught on camera increasingly often. An ordinary CCTV camera with good night vision can snap a low quality image. Amateur meteor observers are also collecting extensive data on sprites.
Oscar van der Velde. It is short for "Emissions of Light and Very low frequency perturbations due to Electromagnetic pulse Sources", but that is something "hardly any scientist can spell out for you", according to Fullekrug. ELVES are fleeting, lasting for less than a millisecond. The storm conditions necessary to make an ELVE pronounced here include a particular type of lightning, with a very sharp rise in current.
Unlike for sprites, to get an ELVE the discharge has to be very sharp, so the two rarely occur at the same time. ELVES occur more often than sprites, with about 1 in lightning flashes producing one. Small storms are just as likely to make them as big storms, as a really fast current can happen in any storm. ELVES are mainly white because they're so intense. I've not seen one myself, though I've been looking quite a bit. View image of Artwork showing blue jets Credit: The first problem is that they're blue.
Blue atmospheric phenomena are hard to study from the ground, because the atmosphere is so good at scattering blue light. They're also very narrow and rare. Researchers do know that there is another phenomenon called a gigantic jet, which seems to be a hybrid of a blue jet and a sprite.
They are broader, wedge-shaped jets of light and easier to see.
They can last ms, so they are relatively slow compared to other storm events. Perhaps only one in ten or one in a hundred sprites will combine with a blue jet to make a gigantic jet. The green, blue and red shapes of the auroras, swirling over the two poles of the Earth, are a visible map of events that happened thousands of kilometres away.

When the solar wind — charged particles from the Sun that brush past our planet — meets the Earth's magnetic field, the two interact. The particles from the Sun slide along the contours of the magnetic field towards the poles.
When they reach the upper atmosphere, they interact with gases. The particles can give the air molecules enough energy to release electrons, causing them to glow in a range of colours. You can imagine it like a sheet flapping in the wind, and every once in a while it will get really messed up and that's when these dramatic events happen. Earth is not the only planet with auroras.
Jupiter and Saturn both have unique auroras, as the gases of their atmospheres are very different.
