But STEVE, formally known as Strong Thermal Emission Velocity Enhancement, is different. The sun fires off its biggest solar flare in more than 3 years. Sometimes, STEVE even has a "picket fence" appearance, with green columns of light passing through the ribbon. There’s a never-before-studied aurora gracing night skies around the world, and NASA wants you to try to spot it. In the Northern Hemisphere, the phenomenon is visible from areas farther south than a typical aurora, and it looks like a ribbon of pink or mauve light. Steve is a visible strip of ionised gas, travelling at 6.4km (4 miles) a second. The newfound aurora, named Steve (short for Strong Thermal Emission Velocity Enhancement), looks like a purple light with some green features. Cool I’m having a Steve attack ( WOW!) Auroras, by contrast, usually are shimmering green ribbons. Scientists have now learned, despite its ordinary name, that STEVE may be an extraordinary puzzle piece in painting a better picture of how Earth's magnetic fields function and interact with charged particles in space. For the first time, scientists have ground and satellite views of STEVE (short for Strong Thermal Emission Velocity Enhancement), a thin purple ribbon of light. For a while, STEVE's origins were elusive. Follow Elizabeth Howell on Twitter @howellspace.

Yep - it's called Steve! like this comment or reply if you agree ( you will ), Cool thing! To spot Steve, Nasa has some tips: A 2018 study showed that its glow, unlike one leading hypothesis had proposed, does not result from charged particles falling into the atmosphere. It's proper name is Strong Thermal Emission Velocity Enhancement - or Steve for short - and it is sometimes seen during displays of the Aurora Borealis. Scientists think that Steve … Nasa says Steve's purple emissions are likely a result of ions moving at supersonic speed. Auroras — and Steve — occur because the sun spews "a glitter bomb of charged particles" that stream 93 million miles (150 million kilometers) toward Earth, NASA … It mostly emits light in purple hues and can last for up to an hour, sometimes accompanied by "a rapidly evolving green picket fence-like" aurora. Read about our approach to external linking. Two photographs of the Steve arc show its purple color and the picket-fence aurora that sometimes appears alongside Steve. The phenomenon was discovered in 2016 by citizen scientists in western Canada. This data is used by Eric and his colleagues at the University of Calgary, and by researchers around the world, to investigate Space Weather – the physical processes that create the aurora and Earth’s radiation belts. A typical aurora — sometimes called the northern lights or the southern lights, depending on the hemisphere in which it's located — occurs when charged particles from the sun interact with Earth's oxygen and nitrogen molecules. According to NASA, the STEVE aurora is unique in appearance and also occurs at lower latitudes than most of the modern lights. Steve is short for Strong Thermal Emission Velocity Enhancement, and is a new kind of aurora on earth.
