Photographer Captures Eerie And Majestic Sky ‘Jellyfish’ Throughout a Storm
In case you’ve ever appeared up throughout a thunderstorm and glimpsed a crimson jellyfish sitting excessive within the sky, you were not hallucinating.
These tentacle-like spurts of crimson lightning are referred to as sprites. They’re ultrafast bursts of electrical energy that crackle by the higher areas of the ambiance – between 37 and 50 miles (60 and 80 kilometres) up within the sky – and transfer in direction of area, in keeping with the European House Company.
The phenomenon is a uncommon sighting: It lasts simply tenths of a second and may be onerous to see from the bottom because it’s usually obscured by storm clouds. However Stephen Hummel, a dark-skies specialist on the McDonald Observatory, captured a spectacular picture of one in all these sprites on July 2 (proven above) from a ridge on Mount Locke in Texas.
“Sprites often seem to the attention as very transient, dim, gray constructions. It’s essential be on the lookout for them to identify them, and oftentimes I’m not sure I truly noticed one till I test the digital camera footage to verify,” Hummel informed Enterprise Insider.
On the night time he snapped this photograph, he’d recorded four half of hours of footage earlier than capturing the sprite on movie.
“Total I’ve most likely recorded near 70 hours’ price of footage and stills this yr, and caught about 70 sprites,” he stated, including that half of these had been in a single storm.
Jellyfish sprites may be seen glimpsed from area
Davis Sentman, a professor of physics on the College of Alaska who died in 2011, proposed the title “sprite” for this sort of climate phenomenon. He stated the title was “effectively suited to explain their look”, for the reason that phrase evokes the lightning’s fairy-like, fleeting nature.
Some sprites, just like the one Hummel photographed, are jellyfish-shaped. Others are simply vertical columns of crimson mild with tendrils snaking down: these are referred to as carrot sprites.
Jellyfish sprites may be huge – the one Hummel photographed was “most likely round 30 miles lengthy and 30 miles tall,” he stated. Some may be seen from greater than 300 miles (500 kilometres) away.
They happen as a result of when lightning strikes the bottom, it tends to launch constructive electrical power that must be balanced out by equal and oppositely charged power elsewhere within the sky. So sprites are discharges that steadiness the equation.
“The extra highly effective the storm and the extra lightning it produces, the extra probably it’s to provide a sprite,” Hummel stated.
Whereas much like common lightning, which shoots between electrically charged air, clouds, and the bottom, sprites occur a lot farther from Earth’s floor.
Astronauts typically spot them from the Worldwide House Station.
As a sprite sparks, it turns crimson due to nitrogen floating excessive in Earth’s ambiance. The fuel will get excited by the burst of electrical energy and emits a crimson glow.

Because the sprites’ discovery in 1989, scientists have noticed them over each continent besides Antarctica.
