NASA spacecraft orbiting Jupiter captured the colorful electronic bursts on Earth for the first time-elves and elves



  • NASA Juno The spacecraft discovered that Jupiter’s atmosphere would produce electrical bursts similar to lightning, called transient luminous events.
  • On earth, these colorful lights will be during thunderstorms lightning The striker produces red tendrils above the clouds, called elves, or luminous discs, called elves.
  • Scientists predict Jupiter will have Elves It̵
    7;s the same with elves, because it has lightning, but no one has caught the flashes of these aliens until now.

NASA’s Juno spacecraft has just captured images of colorful lightning bursts in Jupiter’s atmosphere.

These phenomena include the jellyfish-shaped “elves” and the glow disks called “elves”, which are also high in the earth’s atmosphere during thunderstorms. They were first recorded in 1989. Scientists predict that other planets with lightning, such as Jupiter, will also produce these short-lived glowing events.

But so far, no one has seen the elves or elves of aliens. Juno has been orbiting Jupiter since 2016 and collecting images of its aurora under ultraviolet light. A team of researchers handling these snapshots recently discovered something strange.

“In the process of collating these images, we noticed that we occasionally see these surprising, short-lived, bright flashes,” Juno team researcher Rohini Giles said in a press conference at the annual meeting on Tuesday. Member of the Planetary Science Department of the American Astronomical Association.

She added: “Then, we searched and searched all the data we obtained during the four years of the mission, and found a total of 11 flashes, all of which have very similar characteristics.”

These bursts lasted only a few milliseconds.

Giles’ team published new research on these flashes in the Journal of Geophysical Research: Planets on Tuesday. On earth, elves look like long red tendrils, sometimes disappearing from the diffuse halo. Giles said they happen when lightning strikes produce high-altitude “quasi-static fields.”

In other cases, a lightning strike sends electromagnetic pulses upward. The pulse produces a glowing disc: the wizard.

Giles said: “On Earth, elves and elves appear red due to their interaction with nitrogen in the upper atmosphere.” “But on Jupiter, the upper atmosphere is mainly composed of hydrogen, so they may appear blue or pink. “

Juno was unable to confirm that these events were triggered by a lightning strike because the probe’s lightning detection instrument was located on the opposite side of the spacecraft from the UV imaging instrument. Images of the two instruments were taken at least 10 seconds apart-the delay was too long to capture the same short flash.

But all other factors indicate that these 11 eruptions are short-lived luminous events: they have an extremely short lifespan, emit large amounts of hydrogen, and occur 186 miles (300 kilometers) above Jupiter’s water clouds, which are too high for lightning.

“Whenever Juno makes science Giles said: “Now that we know what we are looking for, it will be easier to find them on Jupiter and other planets. Comparing the elves and elves of Jupiter with the elves and elves on Earth will help us better Get a good understanding of the electrical activity in the planet’s atmosphere.”
