Steve is definitely created in the ionosphere, Nishimura’s team reports, but the purple slither doesn’t appear to be an aurora, which is defined as light emissions caused by energetic electrons. It has garnered the attention of researchers at the European Space Agency (ESA), NASA, and other institutions. Trying to decide if the unanswered question What was Steve?Is it called something else now? Now, new research on the phenomenon suggests that the picket-fence aspect of STEVE is caused by a similar mechanism as the process that results in an aurora. Extreme ultraviolet radiation and X-rays from the sun bombard these upper regions of t… Aurora photographers find new night sky lights and call them Steve - BBC News Quote: A group of aurora enthusiasts have found a new type of light in the night sky and named it Steve. Steve, therefore, is not an aurora at all, but something entirely different: a mysterious, largely unexplained phenomenon that the researchers have dubbed a "sky glow. If an internal link led you here, you may wish to … And that's the cool thing.". (2016) The atmospheric phenomenon was named for a scene in the film Over the Hedge, in which something unknown (a hedge) is given the name Steve. The Alberta Aurora Chasers Facebook group shares pictures its members take of the Northern Lights. Now, scientists understand that the elements of a STEVE originate from two distinct atmospheric phenomenon, writes Toshi Nishimura, a space physicist at … It was a magnificent, mysterious, borderline-miraculous sight, and the group of citizen skywatchers who witnessed it decided to give the phenomenon a fittingly majestic name: "Steve. ‘Steve’ is a band of ghostly lights clearly visible from East to West, all the way from the banks of Hudson Bay to the fjords of British Columbia. Short for Strong Thermal Emission Velocity Enhancement, this strange aurora has puzzled scientists for years. , Robert Lysak, during the fall meeting of the American Geophysical Union in December 2016, suggested "Strong Thermal Emission Velocity Enhancement" as a backronym of STEVE, one that has since been adopted by the team at NASA Goddard Space Flight Center studying the phenomenon. A light pillar is an atmospheric optical phenomenon, which is caused by the reflection of light from ice crystals in cold weather. Dr. Dr. Steve is so strange that it still doesn’t have a formal description. This Steve event was photographed May 8, 2016, at Porteau Cove Provincial Park in British Columbia. Steve (atmospheric phenomenon), a humorously named atmospheric glow; Steve; See also. STEVE's mauve streaks occur due to heated charged particles in the atmosphere, whereas the typical auroras were glowing. Find Northern Lights Atmospheric Phenomenon Steve Which stock images in HD and millions of other royalty-free stock photos, illustrations and vectors in the Shutterstock collection. An atmospheric phenomenon has been discovered by citizen scientists and aurora photographers — and so little is known about it right now that they've named it Steve. In the new University of Calgary study, Gallardo-Lacourt and her colleagues decided to use the data recorded that night to further investigate Steve's mysterious origins. Proper noun . The name for this new atmospheric phenomenon is known by the acronym “STEVE,” which stands for: Strong Thermal Emission Velocity Enhancement. Newly-Observed Atmospheric Phenomenon Named "Steve" Miss Cellania • Tuesday, April 25, 2017 at 12:00 AM. To photographers and stargazers in northern climes, Steve has been a familiar night phenomenon for decades. The recently-discovered atmospheric glow known as STEVE took the sky-gazing world by storm when it first appeared. In late 2016, the backronym "Strong Thermal Emission Velocity Enhancement" was adopted. Source. There is, however, another atmospheric light show that you may be less familiar with: STEVE. But, for the sake of keeping the conversation going, she and her colleagues dubbed the mysterious force a "sky glow.". 1 / 33. New research into a strange atmospheric effect known as STEVE has failed to associate its enigmatic lights with aurora, pointing to the presence of an entirely new type of atmospheric phenomenon. ", Given its coincidence with the northern lights, Steve was just thought to be part of the aurora — the shimmering sheets of nighttime color that appear in the sky when charged plasma particles streak out of the sun, sail across space on solar winds and jolt down Earth's magnetic field toward the planet's poles. The aurora enthusiasts have named it Steve.  The study also showed these phenomena appear in both hemispheres simultaneously. [Aurora Images: See Breathtaking Views of the Northern Lights], According to researchers at the University of Calgary in Canada and the University of California, Los Angeles, Steve does not contain the telltale traces of charged particles blasting through Earth's atmosphere that auroras do. The STEVE phenomenon was discovered in 2016 by citizen scientists in western Canada and the aurora-like phenomenon has long been a mystery for scientists. The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like … For other uses, see, "Introducing Steve - a Newly Discovered Astronomical Phenomenon", "New kind of aurora is not an aurora at all", "Aurora photographers find new night sky lights and call them Steve", "Amateur Sky-Watchers Discover Celestial Phenomenon, Name It 'Steve, "New atmospheric phenomenon named STEVE discovered by aurora watchers", "Meet Steve, a sky phenomenon coming into its own", "Meet 'Steve,' a Totally New Kind of Aurora", "Help NASA Study 'Steve,' a Newfound Aurora Type", "NASA Needs Your Help to Find Steve and Here's How", "New science in plain sight: Citizen scientists lead to the discovery of optical structure in the upper atmosphere", "Steve the odd 'aurora' revealed to be two sky shows in one", "Magnetospheric signatures of STEVE: Implication for the magnetospheric energy source and interâhemispheric conjugacy", "Scientists discover what powers celestial phenomenon STEVE", "Aurora Australis with bonus 'picket fence' wows southern lights chasers in Tasmania", "Aurora-chasing citizen scientists help discover a new feature of STEVE", Eric Donovan's presentation at 2017 ESA Earth Explorer Missions Science Meeting, https://en.wikipedia.org/w/index.php?title=Steve_(atmospheric_phenomenon)&oldid=989863502, Creative Commons Attribution-ShareAlike License, This page was last edited on 21 November 2020, at 13:26. Several distinct layers make up Earth's atmosphere, including the mesosphere, which starts 31 miles (50 km) up, and the thermosphere, which starts at 53 miles (85 km) up. , One of the aurora watchers, photographer Chris Ratzlaff, suggested the name "STEVE" from Over the Hedge, an animated comedy movie from 2006, in which its characters chose that as a benign name for something unknown. They found that the mauve arch occurs when charged particles are heated high up in the earth’s atmosphere. Fellow Aurora Chaser Robert Downie kneels in the foreground while photographer Ryan Sault captures the narrow ribbon of white-purple hues overhead. According to analysis of satellite data from the European Space Agency's Swarm mission, STEVE is caused by a 25 km (16 mi) wide ribbon of hot plasma at an altitude of 450 km (280 mi), with a temperature of 3,000 Â°C (3,270 K; 5,430 Â°F) and flowing at a speed of 6 km/s (3.7 mi/s) (compared to 10 m/s (33 ft/s) outside the ribbon).
