Agriculture, scratching and feathers in the northern and southern lights are among the most distinctive features of the Earth. But our planet does not have a monopoly on Ura. Scientists spied them all over the solar system, and they woven into the sky of Mars, Saturn, Jupiter Even on some moons of the fiery and Essi Planet.
The lights are glowing in the sky Uranusalso. But Aurora is around our most distant planet of sunlight, Neptune, has been exposed to astronomers for a long time.
This has changed with strong infrared tools on the James Web telescope. In a study published on Wednesday in the magazine Nature astronomyScientists reveal a unique Ura, leaking on both sides of the equator in Neptune, which contradicts the incandescent calves that were seen while emitting the pillars of other worlds.
Astronomers are pleased to see the completion of an endeavor to hunt an Urra contracts in making. “Everyone is very excited to prove that it exists, just as we thought,” he said Rosie JohnsonSpace Physics Researcher at the University of Abeestoyeth in Wales, who did not participate in the new study.
This discovery will also allow scientists to study the aspects of Neptune, which was already out of reach. “They use Urara to understand the form of the planet’s magnetic field, which sees the unseen.” Karl SchmidtA planetary astronomer at Boston University has not participated in the new study.
Each Urra world is born differently, but the basics are the same. Active molecules (often from the sun, but sometimes the volcanic moon revolutions) go to an atmosphere and bounce gases. This particle collision briefly causes flashes of light. If the world has a magnetic field, this directs the Auroras website.
Aurras does not always glow in visible light; Saturn, for example, is mostly emitted by UV euro. But it can be observed with the right telescopes.
It has not yet been possible to discover Neptune lamps in the atmosphere.
“Astronomers have tried to discover Aurora Neptune decades ago, and every attempt failed,” he said, “He said,” He said, “He said,” He said, he said, ” Henrik MilinThe world of the planets at the University of Northmoria, England and one of the authors of the study.
Voyageer 2, the only spacecraft flying by Neptune (in 1989), found hints from Aurora. But all follow-up notes-even with the Hubble Space Telescope-failed to sparkle spy.
Fortunately, a web telescope, which was launched in 2021, has become a rescue.
Heidi HamelAnd an astronomer in the Universities Association to Research in Astronomy and another of the authors of the study, has been studying Neptune since the 1980s. She said that if the web is “strong enough to see the first galaxies in the universe, it is better to be strong enough to see things like Aurorae on Nevtune”. “And golly, was.”
Using a telescope near infrared, astronomers have discovered infrared Aroorra in Neptune in June 2023. Unlike the Earth, they do not dance over the Polish, but in the middle. This is because Neptune has a tender magnetic field that tends 47 degrees from the planet’s rotation axis.
New web notes also reveal why Neptune Aurora is not visible yet. Nearly 40 years ago, Voyageer recorded a temperature of about 900 degrees Fahrenheit for Neptune’s upper atmosphere. But the Webb telescope shows that the temperature has decreased, to nearly 200 degrees. The low temperature means that the eurora is dim.
In fact, Aurora from Neptune said, “With less than 1 percent of the brightness we expected, explaining why we did not see it.” James OdonogoA planetary astronomer at the University of Reading in England and one of the authors of the study. “However, this means that we now have a new puzzle on our hands: How do Neptune Creat a lot?”
With the discovery of the Neptune’s Strange Light, the answers may be coming.
“Auroras is like a TV screen,” he said Lee FleischerThe world of planets at Leicester University in England and one of the authors of the study. They “allow us to see the careful dance of operations in magnetism – all of this without being already.”
