Venus’ enigmatic night side disclosed

Scientists have utilized ESA’s Venus Express to display the wind and upper cloud model on the night side for Venus for premiere with astounding results. The study depicts that the atmosphere on the right side of Venus is completely different from the side that faces the Sun, displaying unforeseen and prior unseen cloud types, anatomies and dynamics associated to characteristics on the planet’s surface.

Javier Peralta of the Japan Aerospace Exploration Agency (JAXA), Japan, and lead author of the new study published in the journal Nature Astronomy said that they have been for the first time successful in characterizing how the atmosphere flows on the night side of Venus in an all-encompassing scale. He also said that while the atmospheric flow on the planet’s daytime facet has been substantially traversed, a lot yet remains to be discovered about the night side. It was found that cloud motifs there vary to those on dayside leveraged by Venus’ topography.

Venus’ atmosphere is governed by strong winds that spin around the planet far speedily than Venus itself rotates. This super rotation marks Venusian winds rotating up to 60 times faster than the planet below, shoving and heaving along clouds within the atmosphere as they go. These clouds are swiftest at the upper cloud level some 65 to 72 km above the facade.

Peralta explains that decades have passed studying these super-rotating winds by tracing how the overlying clouds move on Venus’ dayside. These are plainly perceptible in images obtained in ultra violet light. But our replica of Venus is unable to repeat this super rotation which emphasizes the fact there is a missing link.

The team made use of visible and infrared Spectrometer (VIRTIS) on ESA’s Venus Express spacecraft and they found that VIRTIS sanctioned the clear visibility of the clouds for the first time permitting the exploration that was not a success for the previous team and thereby coming across unanticipated and astounding results.
