A wave from pole to pole in the cloud tops that doesn’t move – but then disappears? Another Venus conundrum emerges.

A massive, un-moving structure has been discovered in the upper atmosphere of Venus, reports the IB Times.

Scientists detected the feature with the Jaxa’s Akatsuki spacecraft and they believe it is some sort of gravity wave – although they do not understand how it ended up at the altitude of cloud tops.

The bow-shaped structure was first spotted in December 2015 and a team led by scientists from Rikkyo University in Japan were able to observe it over several days.

It measured 10,000km in length and was brighter and hotter than the surrounding atmosphere. When scientists attempted to observe it again a month later, it had disappeared. The team published their findings in the journal Nature Geoscience.
