The preferred usage is transient luminous event (TLE), because the various types of electrical-discharge phenomena in the upper atmosphere lack several characteristics of the more famili… novel imaging instrumentation developed and built at Stanford. of the photograph of the flash stoked a great amount of scientific interest in Preliminary results from the sprites94 aircraft campaign: 1. red sprites. [2005] indicate that elves produce significant ionization Japan, and South Africa. ; Bonfond, Bertrand; Gladstone, R.G. in-the-field TLE observation campaigns carried out all over the world with If you’re looking for sprites or elves dancing in the forest after dark, you might be disappointed—but in a way, they do exist. above a thunderstorm [Franz et al., 1990], following years of intermittent Examples of various kinds of TLEs are shown in Figure "sprites" and "elves" to reflect their fleeting and hard-to-catch nature (and Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. Much of the VLF Group's work has been driven by ScienceDaily. In fact, these elves and sprites on Jupiter stand as the first of their kind discovered on another world; their kind being transient luminous events, or TLE’s. Lockheed Martin Space in Denver built and operates the spacecraft. Stunning, evanescent events called sprites and elves are sometimes seen prancing above thunderclouds on Earth. Marshall, R., R. Newsome, and U. Inan, Fast photometric imaging using Illustration of sprite depicted at Jupiter; image of south pole of Jupiter and a potential transient luminous event, 2020 Tied for Warmest Year On Record: NASA, Climate Change: Billions in Flood Damages, Pulsar Acceleration: Milky Way's Dark Side, Platypus: How Odd Mammal Got to Be So Bizarre, Jupiter's Atmospheric Beauty Is More Than Skin Deep, NASA Juno Finds Jupiter's Jet-Streams Are Unearthly, Juno Mission to Jupiter Delivers First Science Results, NASA's Juno Spacecraft Sends First in-Orbit View, Turn Off That Camera During Virtual Meetings, Environmental Study Says, Electric Cooker an Easy, Efficient Way to Sanitize N95 Masks, Study Finds, Three Reasons Why COVID-19 Can Cause Silent Hypoxia, Conductive Nature in Crystal Structures Revealed at Magnification of 10 Million Times, X-Rays Surrounding 'Magnificent 7' May Be Traces of Sought-After Particle, Light-Controlled Higgs Modes Found in Superconductors; Potential Sensor, Computing Uses, Eggs Reveal What May Happen to Brain on Impact, Appreciating a Flower's Texture, Color, and Shape Leads to Better Drone Landings, One-Dimensional Quantum Nanowires Fertile Ground for Majorana Zero Modes. Sentman, D. D., E. M. Wescott, D. L. Osborne, D. L. Hampton, and M. J. Heavner, It is the first time these bright, unpredictable and extremely brief flashes of light — … lower ionosphere by lightning. within a few years a menagerie of different kinds of flashes had been Weather Underground provides local & long-range weather forecasts, weather reports, maps & tropical weather conditions for locations worldwide In particular, we suggest that these are elves, sprites or sprite halos, three types of TLEs that occur in the Earth's upper … Group include: Recent study of TLEs by the VLF Group has been funded by the Office of Naval Juno scientists could also rule out that these were simply mega-bolts of lightning because they were found about 186 miles (300 kilometers) above the altitude where the majority of Jupiter's lightning forms -- its water-cloud layer. Inan, U. S., T. F. Bell, and J. V. Rodriguez, Heating and ionization of the Gigantic jets were first documented in July 2002. Portions of this material are based upon work supported by the National Science Foundation under Grant No. pinned down), and the entire category of flashes came to be known as transient Specimens : Transient Luminous Events in the Mesosphere. New results from NASA's Juno mission at Jupiter suggest that either "sprites" or "elves" could be dancing in the upper atmosphere of the solar system's largest planet. scientific inception in 1989, making numerous theoretical contributions and They are generally triggered by positive cloud to ground lightning strokes. The different kinds of flashes were given fanciful names like „sprites” and „elves” to reflect their fleeting and hard-to-catch nature and the entire category of flashes came to be known as „transient luminous events” (TLEs). Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. Elves (short for Emission of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources) appear as a flattened disk glowing in Earth's upper atmosphere. Abestrobi. ATM-0836326. luminous events (TLEs). Marshall, R. A., and U. S. Inan, High-speed telescopic imaging of sprites. Note: Content may be edited for style and length. TLE’s were brought into the spot light in 1988 after researchers by accident imaged a number of sprites over the great … Transient Luminous Event (TLE) are flashes and glows that appear above storms that are results of activity occurring in and below those storms. that elves are the most dominant type of TLEs and estimate the global occurrence rates of sprites, halos, and elves to be ∼1, ∼1, and ∼35 events/min, respectively [Chen et al., 2008]. Gerken, E. A., and U. S. Inan, A survey of streamer and diffuse glow dynamics lightning-induced ionospheric flashes referred to as 'elves'. Just in time for Halloween, NASA announced results from the space agency's Juno mission that suggest "sprites" or "elves" could be frolicking in Jupiter's upper atmosphere. imaging of transient luminous events. and elves with intensified video and broadband array photometry. luminous events. And UVS recorded that the spectra of the bright flashes were dominated by hydrogen emissions. Gigantic jets are the rarest of the known Transient Light Events (TLEs), which are upper atmospheric optical phenomena associated with thunderstorms, like red sprites, blue jets and elves. Publication Locations for results from the sprites94 aircraft campaign: 2. blue jets. Almost resembling a jellyfish, sprites are transient luminous events triggered by lightning discharges from thunderstorms far below. Then, in the summer of 2019, researchers working with data from Juno's ultraviolet spectrograph instrument (UVS) discovered something unexpected: a bright, narrow streak of ultraviolet emission that disappeared in a flash. Chen, A. Elves and sprites on Jupiter? More information about Juno is available at: Materials provided by NASA/Jet Propulsion Laboratory. This changed in NASA/Jet Propulsion Laboratory. Inan, U. S., C. Barrington-Leigh, S. Hansen, V. S. Glukhov, T. F. Bell, and They bear whimsical names like sprites, elves, gnomes and more. Barrington-Leigh, C. P., U. S.
