In the first Hubble Space Telescope, he photographed images that document the birth of a huge storm at Neptune, a discovery that can reveal insight into the inner workings of less well-understood icebergs, NASA said.
Like Jupiter's Big Red Stains, Neptune Large dark spots are storms that arise from high-pressure atmospheric pressure. By contrast, storms on the Earth are shaped around the low pressure area.
Scientists have seen a total of six dark spots on Neptune over the years. Voyager 2 identified two storms in 1989. Since Hubble was launched in 1990, he saw four more storms, NASA says.
Researchers have analyzed Hubble's photograph of ice diva recorded over the past few years and recorded the rise of a new big dark spot that became visible in 2018.
By studying the clouds that appeared two years before the new Great Dark Point, researchers conclude that dark spots are much deeper into the atmosphere of Neptune than previously thought.
Hubble's images also helped researchers determine how often Neptune gets dark spots and how long they last.
It is not only that scientists give insight into the inner action of the giant jewels, but also have implications for the study of exoplanets of similar size and composition.
"If you study Exoplanets and want to understand how they work, you first need to understand our planets," says Amy Simon, a planetary scientist from NASA's Space Flight Center in the United States.
"We have so little information on Urana and Neptune," said Simon, the lead author of the study, published in the journal Geophysical Research Letters.
Scientists first saw the Heavenly Spot on Neptune in 1989 when NASA's Voyager 2 probe passed past the mysterious blue planet. As the spacecraft increased, he recorded two huge storms that were boiling in the southern hemisphere of Neptune.
Scientists have called storms "Great Dark Spot" and "Dark Spot 2"
Only five years later, Hubble Space Telescope shot sharp Neptune's painters who discovered that the Great Black Stain of Earth's Size and the Lesser Dark Stain 2 disappeared.
In 2018, there appeared a new Great Dark Spot on Neptune, almost identical in size and shape to what Voyager saw in 1989.
The researchers analyzed Hubble's footage of less dark spots that emerged in 2015 when they discovered small, bright white clouds in the region where the Great Dark Spot appeared later in 2018.
"We have been so busy following this storm of storm since 2015, we did not expect to see another big one soon," Simon said.
High clouds are made of methane crystals, giving them a characteristic light white color.
Scientists suspect that these methane clouds are accompanied by storms that create dark spots, hovering over them in the way that cloudy clouds cover the high mountains on Earth.
