NASA said that for the first time a lightning “spirit” was found on Jupiter



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

These phenomena include jellyfish-shaped “spirits” and glowing discs called “spirits”, which are also highly occurring 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’s team is in Journal of Geophysical Research: Planets 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. The images between the two instruments are at least 10 seconds apart-the delay is too long to capture the same short flash.

But all other factors indicate that these 11 eruptions are short-lived luminous events: their lifespan is extremely short, they emit a lot of hydrogen, and they occur 186 miles (300 kilometers) above Jupiter’s water cloud, too high for lightning. .

Giles said: “Every time Juno passes the science exam, we continue to look for more signs of elves and monsters.”

“Now that we know what we are looking for, it will be easier to find them on Jupiter and other planets. Comparing Jupiter’s elves and elves with those on Earth will help us understand better Electric activity in the planet’s atmosphere.”
