At school we looked at this, on school computers! It has been given the name Steve… For a while, STEVE's origins were elusive. Receive mail from us on behalf of our trusted partners or sponsors? The phenomenon was discovered in 2016 by citizen scientists in western Canada. Satellite information further revealed how the "picket fence" aspect of STEVE develops. Astronomers are trying to better understand the phenomenon, and Nasa actually funds a science project asking ordinary citizens to log sightings. But Steve is not a normal aurora. A citizen scientist working with NASA's Aurorasaurus project has unearthed an exciting piece of scientific history. Steve is a visible strip of ionised gas, travelling at 6.4km (4 miles) a second. While Steve goes through the same large-scale creation process as an aurora, it travels along different magnetic field lines than the aurora. A citizen science project called Aurorasaurus, funded by NASA and the National Science Foundation, wants your help gathering photos so they can learn more about this mysterious phenomenon. A citizen science project called Aurorasaurus, funded by NASA and the National Science Foundation, wants your help gathering photos so they can learn more about this mysterious phenomenon. Two photographs of the Steve arc show its purple color and the picket-fence aurora that sometimes appears alongside Steve. To spot Steve, Nasa has some tips: Since 2015, a mysterious purple light in the sky has baffled NASA. New York, Skip to comments. In the fall of 2014, Elizabeth MacDonald, a physicist at NASA, ... Steve differs in several ways from the classical aurora. Thank you for signing up to Space. Since 2015 Nasa has been studying the purple light in the sky. 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. Rather than occurring in an oval shape, it is a bizarre 'picket fence' structure. Credits: NASA Goddard's Conceptual Image Lab/Krystofer Kim The uniqueness of Steve is in the details. In this region, the waves can both energize electrons and move them out of the magnetosphere, creating the picket-fence appearance, which happens simultaneously in the Northern and Southern hemispheres. However, the first accurate determination of what STEVE is was not made until after members of a Facebook group called Alberta Aurora Chasers named it, attributed it to a proton aurora, and called it a "proton arc". "As commercial cameras become more sensitive and increased excitement about the aurora spreads via social media, citizen scientists can act as a 'mobile sensor network,' and we are grateful to them for giving us data to analyze," lead author Toshi Nishimura, a space physicist at Boston University, said in the same statement. 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. NASA shares photo of 'Steve' - the mystery purple aurora that rivals the northern lights The Mirror UK ^ | 17 Nov 2020 | Shivali Best Posted on 11/18/2020 12:32:45 AM PST by blueplum. It consists of a “purple ribbon in the sky, with a green picket fence structure underneath”, according to NASA, which named it “Strong Thermal Emission Velocity Enhancement” – or STEVE … It's amazing, but Steve?I saw this and I just laughed my head off because of the name#STEVEISDABEST, Steve backshall will be happy lol, I wonder how many of those things happen a year, Steve photographed from the Isle of Lewis. You will receive a verification email shortly. Meet "Steve," a strange, new aurora feature discovered by citizen scientists and verified by the European Space Agency's (ESA) Swarm satellites. A new finding about the formation of streaks within the aurora-like STEVE phenomenon brings scientists one step closer to solving the mystery. It may not be an aurora at all, according to some. It's an important field of study for scientists to better understand how these particles may interfere with radio communications and GPS signals.

As well as an abbreviation, the name Steve also refers to the 2006 children's film Over the Hedge, where the characters give the name to a creature they have not seen before. In order to learn more about this new light show, atmospheric researchers are now encouraging citizen scientists of the northern hemisphere to keep an eye out for Steve. Auroras, by contrast, usually are shimmering green ribbons. Scientists have recently confirmed STEVE is a unique phenomenon and not a kind of aurora, as previously thought. And if you have a news tip, correction or comment, let us know at: community@space.com. Scientists think that Steve … This interaction excites the molecules and causes them to glow. The science team said the new results will help them learn how to predict the paths of particles flowing through the ionosphere. The authors also pointed out that STEVE can show up at the same time as an aurora does, which makes it even harder to figure out which is which. Nasa releases new images of stars and galaxies. 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 … 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. A study based on the research was published April 16 in the journal Geophysical Research Letters. A 2018 study showed that its glow, unlike one leading hypothesis had proposed, does not result from charged particles falling into the atmosphere. According to NASA, the STEVE aurora is unique in appearance and also occurs at lower latitudes than most of the modern lights. like this comment or reply if you agree ( you will ), Cool thing! The more observations of Steve the better, as far as NASA is concerned. STEVE is an atmospheric optical phenomenon which appears as a light ribbon in the sky, formally discovered in 2017 by aurora watchers from Alberta, Canada. "This occurs outside the auroral zone, so it's indeed unique," Bea Gallardo-Lacourt, a space physicist at the University of Calgary in Alberta, Canada, and co-author of the new research, said in a statement released by the American Geophysical Union, which published the new research. Nasa says Steve's purple emissions are likely a result of ions moving at supersonic speed. In order to learn more about this new light show, atmospheric researchers are now encouraging citizen scientists of the northern hemisphere to keep an eye out for Steve. Space calendar 2020: Rocket launches, sky events, missions & more! STEVE's mauve streaks occur when charged particles are heated up high in the atmosphere, further south than typical auroras. Read about our approach to external linking. Space is part of Future US Inc, an international media group and leading digital publisher. New work helps to codify the cause and properties of "Steve," an aurora-like phenomenon documented by citizen scientists as it streaked across the sky in western Canada. STEVE is an atmospheric optical phenomenon which appears as a light ribbon in the sky, formally discovered in 2017 by aurora watchers from Alberta, Canada. From NASA's Goddard Space Flight Center 2 / 2 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. Astrophotographer Paul Zizka shared this photo of the aurora phenomenon "Steve" — then called a potential proton arc — with Space.com in … The measurements included information about Earth's magnetic and electrical fields in the magnetosphere, the region of Earth's atmosphere where the planet's magnetic field is stronger than any influence coming from the sun. STEVE (Strong Thermal Emission Velocity Enhancement) is an atmospheric optical phenomenon that appears as a purple and green light ribbon in the sky, named in late 2016 by aurora watchers from Alberta, Canada.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 … Please refresh the page and try again. But STEVE, formally known as Strong Thermal Emission Velocity Enhancement, is different. Nasa has shared amazing photos of a mystery purple space phenomenon with an unexpected name. The data revealed waves moving from Earth's magnetosphere to the ionosphere. And it turns out, the public can help, as citizen scientists did by providing STEVE photographs for this research. New work helps to codify the cause and properties of "Steve," an aurora-like phenomenon documented by citizen scientists as it streaked across the sky in western Canada. Visit our corporate site. Nasa says Steve… Cool I’m having a Steve attack ( WOW!) According to NASA, the STEVE aurora is unique in appearance and also occurs at lower latitudes than most of the modern lights. An aurora borealis-like phenomenon observable in Canada — but much farther south than the northern lights appear — over Childs Lake, Manitoba. Citizen Scientists Help Discover A New Feature of STEVE | NASA There was a problem. Future US, Inc. 11 West 42nd Street, 15th Floor, 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. Nasa said: "What's creating these long glowing streaks in the sky? The new study examined satellite data gathered above STEVE events in April 2008 and May 2016.

By spotting the mysterious type of aurora, scientists should hopefully be able … But Steve is not a normal aurora. There’s a never-before-studied aurora gracing night skies around the world, and NASA wants you to try to spot it. Scientists finally have an explanation for the weird celestial phenomenon called STEVE, which looks and behaves a lot like an aurora but has key differences. Follow us on Twitter @Spacedotcom and on Facebook. Besides CERES project, Aurorasaurus, a community science project funded by NASA, asks the public to help them with more photos of STEVE Aurora. © 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. Receive news and offers from our other brands? When physics professor Eric Donovan from the University of Calgarysaw their photographs, he suspected that was not the case beca… STEVE has been observed by auroral photographers for decades, with some evidence to suggest that observations may have been recorded as early as 1705. All-sky cameras showed that Steve appears at much lower latitudes. Our image of the day. 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. 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. Sometimes, STEVE even has a "picket fence" appearance, with green columns of light passing through the ribbon. 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. 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. , let us know at: community @ space.com excites the molecules and causes to.
