Excerpt from The Verge
Written by Andrew Liptak
The Japanese probe Akatsuki has observed a massive gravity wave in the atmosphere of Venus. This is not the first time such a wave was observed on the Solar System’s second planet, but it is the largest ever recorded, stretching just over 6,000 miles from end to end. Its features also suggest that the dynamics of Venus’ atmosphere are more complex than previously thought.
An atmospheric gravity wave is a ripple in the density of a planet’s atmosphere, according to the European Space Agency.
