Astroboffins find and explore a new planetary wonder

Fresh storms rush through Neptune's air every four to six years, screaming the name Big Darkness – and scientists have captured another form of planetary wonder using the Hubble space telescope.
Boffins has seen these places appear six times over the years, since Voyager 2 first cared in 1989. Like Great Red Spot, Jupiter, Neptune's Great Dark Spot is brewing a storm in the atmosphere of the planet under high pressure conditions. The similarities between storms on the two planets end there, however. Jupiter storms can relax for hundreds of years. Indeed, the Great Red Spot has been seen since 1830 and could be up to 350 years old.
Those on Neptune are blending much faster and they can last up to six years. However, the survival of two-year storms is likely to be the norm, according to the paper published in Geophysical Research Letters on Monday. The research documents Hubble's photographs taken from Neptune in 2018, which, when explored, have therefore taken place to capture the birth of the planet's newest place.
Violent winds destroy places
“It was certainly a surprise,” said Amy Simon, the first author of the paper and a planetary scientist at NASA. “We used to look at Great Red Spot Jupiter, which had been there for over a hundred years.” T
Simon and his colleagues at the University of California Berkeley decided to focus on the growth of Neptune's Big Darkness 2018. They were earlier studying a smaller dark place that appeared in 2015, when they had the chance to throw small bright white clouds covering an area of Neptune's surface. Then, looking at pictures taken three years later, other Great Wild Spaces assembled in the same region where the former clouds were snoring.
“We were so busy tracing this smaller storm from 2015, that we didn't necessarily expect another one so soon,” said Simon. The white color of the clouds comes from the methane ice crystals, and they were the brightest in 2016 and 2017, resulting in the full storm in 2018.

Simulations show that the bright white clouds, the deeper the storm. The storm winds on Neptune spread widely in the planet's atmosphere and over time these break up the Great Dark View. The researchers hope to study the shape of the fortune and measure wind speeds in the storms to study the strange weather patterns of the planet.
“We have never measured winds directly within Neptune's dark portraits, but we estimate that the wind speed in the ball plot of 328 feet (100 meters) per second, is quite similar to the wind speed within Jupiter's Great Red Spot, ”Says the author of the paper and planetary scientist at the University of California, Berkeley.
“If you are studying the outlets and you want to understand how they work, you need to understand our planets first,” added Simon. “We have so little information about Uranus and Neptune.” ®
