Hubble shows stormy Uranus coming in summer



NASA has released new pictures this week showing how the 42-year summer on Uranus is quite powerful, while Neptune is smashed with a thousand-mile wide storms.

Thanks to the extreme inclination of Uranus – the planet revolves almost completely on its side – the sun shines almost over the sky in summer relative to the Uranus' North Pole and is not set for decades, scientists believe it can

? massive but narrow methane gas cloud that can become bright enough to be photographed by amateur astronomers Gang circles the planet north of the equator, and scientists are puzzled as to how such bands form on Uranus and Neptune, as both planets dominate jets from westward blowing wind, which are generally very wide.

Neptune also stormy weather in photos

Neptune also shows signs of stormy weather. Currently, summer in its southern hemisphere is experiencing a dark, stormy spot in the northern hemisphere that NASA says has a diameter of about 6,800 miles – about 2.5 times the width of the continental United States. The storm is accompanied by white clouds, which form when the ambient gas is forced up and over the vortex before the storm.

The methane gas then freezes to ice crystals in the upper atmosphere, similar to clouds as air is pushed over mountains here on earth.

Other similar storms have previously been observed on Neptune. Voyager 2 took shots of two previous dark storms on Neptune as it flew by in 1989 and captured three former storms until 1993.

Hubble is the only telescope that currently has the blue light sensitivity to capture these storms in Neptune's atmosphere, which appears astronomically very fast and disappears. A study conducted by Andrew Hsu, a student at the University of California at Berkeley, estimated that dark spots on Neptune formed about every four to six years and faded again after about two years.

The Big Red Spot, a gigantic storm that is about twice the diameter of the earth that swirls 22 degrees south of the equator through the atmospheric band of Jupiter, has been observed since the late 19th century. It may even have been discovered as early as the 17th century, which would make it centuries old.

Surveillance of the Ice Giants

According to a statement published by NASA, published with the new images, the planets "have no solid surface but coats" of hydrogen and helium surrounding a water-rich interior and perhaps one rocky core are wound. Atmospheric methane absorbs red light, but leaves blue-green light back into space, giving each planet a cyan hue. "

To determine what the weather is on the farthest planets, NASA must take many pictures over a longer period of time to monitor changes in the planet's atmosphere over time and hopefully give them a long-term record. As such, Hubble has periodically taken photos of the planets as part of a long-term surveillance mission.
