NASA researchers got a rare opportunity to study the atmosphere of Uranus and his rings this month, when the ice giant passed between the earth and a remote star, creating a “wonderful hidden”.
This rare event lasted about an hour on April 7 and was only visible from Western North America. The last mysterious time is great Uranus It happened in 1996, so NASA came. An international team that includes more than 30 astronomers, led by NASA planetary scientists Langley Research Center In Virginia, 18 observations were used to collect data.
“This was the first time that we have collaborated on this range for the sake casingWilliam Sonders, the world of planets in Langley, said, In a statement.
“I am very grateful to every team member and every observatory to participate in this extraordinary event,” Sonders added. “By monitoring magic from many adults TelescopesWe are able to measure the light curve and determine the uranus properties in the atmosphere in many layers of height. “

For example, scientists measured the temperatures and formed the stratosphere in Uranus, the middle layer of its atmosphere. They managed to see how the stratosphere changed since 1996, when NASA got a snapshot of Joe Uranus during the last major stars.
The data that has just been collected can help ” Uranus exploration efforts in the futureThe agency officials said in the statement.
Uranus, currently about two billion miles (3.2 billion km) from landIt does not have a solid surface. Instead, the planet has a soft surface that represents a mixture of water, ammonia and methane. The researchers call Uranus the giant ice because the interior is largely formed by these liquids, all of which have low frozen points. The planet’s atmosphere mostly consists of hydrogen and helium.

“The atmosphere of the giant planets for gas and ice [Jupiter, Saturn, Uranus and Neptune] Emma Dal, a post -PhD researcher at the California Institute of Technology, which helped collect observations from the NASA infrared facility in Hawaii, said in the same statement that the exceptional air laboratories because they do not have solid surfaces.
She added: “This allows us to study the formation of the cloud, storms and wind patterns without the additional variables and the effects of the surface, which may complicate simulations very quickly.”
