KYIV. February 9 UNN Astronomers using the Hubble Space Telescope received new images of the icy giants of Uranus and Neptune. At Uranus, with the arrival of summer, a brighter Nordic polar cloud cap began to appear, while a large, dark storm was visible on Neptune, reported on the site of the telescope, reports UNN .
Lesser-known planets in the solar system. A single interplanetary automatic station – "Voyager-2" – studied them nearby. All other observations of these planets come from the Earth or their orbit near the Earth. Giant atmosphere processes, particularly the formation and evolution of major hurricanes and their interaction with the environment, as well as seasonal changes in the atmosphere from decades to decades, are of particular interest. for scientists.
OPAL program (Outer Planet Atmospheres Legacy), during which annual observations of these planets are organized. The north pole of Uranus shows a bright and giant white area, which has already been described as a "polar cap" by scientists. It can be a long-term storm and can be formed due to seasonal changes in atmospheric flux. When Voyager 2 flew over Uranus in 1986, this structure was less noticeable, but the planet was winter.
The Neptune described by Hubble reveals the dark anticyclone that appeared in the southern hemisphere of the planet in the summer, the fourth largest anticyclone observed by the telescope. Two other similar atmospheric formations were discovered by Voyager-2 spacecraft in 1989, when the large black spot was discovered, whose diameter was only three times lower than Hurricane Jupiteran. : Scientists have noticed the origin of a planet from the dust of stars
Previously, the telescope had already traced the fate of one of these storms. In the vicinity of the black storm, apparent bright white clouds formed during the upward movement of the airflow caused by the vortex, resulting in the formation of ice-cold methane crystals. Similar clouds are forming on the Earth above the mountains. The long cloud, visible to the left of the storm, is not part of it
According to UNN the NASA space agency announced its decision to send a mission to Uranium from 2034 to 2036. This program is considered one of the most important missions planned for the coming decades.
