A New Study Reveals the Makeup of Uranus’s Atmosphere

During this period, the South Pole region entered the winter and the north polar region, as soon as they approached the summer, followed the investigation team. Observing the planet at four different points, they could see the gradual change of seasons in the years, the gradual change of chapters affects the planet. The top row shows how the planet looks like when impinging with visible light.

It is a false colorful image based on light and infrared observations that appear on the second row. The green atmosphere shows less methane than blue and shows the lack of red meter. In the poles, the low levels of the atmospheric methane (remember, on the side of the planet, the top and bottom) indicate seasonal variability at the level of methane. In this row, the green South Pole in the most imagery left is going to the darkness of the green. In the other three images, the green, low methane region can enter the appearance of the North Pole. (The fourth row indicates the lack of the same methane change, but without coloring.)

What about the third row? This has not been painted using a aerosol abundance, visible light and infrared images. Cloudy areas with higher aerosol abundance of light areas are clear with abundance of low aerosol areas. These images are what is remarkable have Seasonal change. The Arctic region was in the beginning (in 2002), but as summer progressed (in 2012, 2022). On the contrary, the Antarctica region seems to be cleared as the winter falls. The team believes that this seasonal changes are evidence that the sunlight changes the level of aerosol fog in the planet.

Although the results of this work covers a long 20-year period, this only reflects a period of seasonal change in the uranium atmosphere. The research team will continue to follow the Uranus to collect more information, as the polar districts go through the news.
