The discovery of a huge bow structure in the Venus atmosphere


British "nature? A study published in the online journal of Earth Science" 16, said the Japan Aerospace Exploration Agency (JAXA) of the "dawn" (Akatsuki) detector, a giant static structure found in high-speed mobile in the atmosphere of venus. This unexpected finding suggests that Venus’s atmosphere is more complex than previously thought.

Venus is harsh, but the pressure and temperature of a certain part of the atmosphere is very similar to the earth, and has been a subject of great interest to scientists. However, the atmosphere of Venus is fantastic, the earth’s atmosphere is more dense than the thick clouds in the upper atmosphere, can move at a speed of 100 meters per second, almost 60 times the speed of the slow rotation of venus. The highest wind speed of the earth is only about 1/10 to about 1/5 of the rotation speed.

"dawn" spacecraft is Japan’s first star celestial meteorological satellite, the main purpose is to study the atmosphere of venus. It failed to enter orbit, but at the end of, the second attempt to successfully enter the orbit of Venus, and in April last year to open a formal exploration of venus.


, Japan Rikkyo University researcher Taguchi Ma and his colleagues, a huge bright bow area was found in the upper atmosphere of Venus clouds, stretching 10 thousand kilometers. "Dawn" spacecraft on multiple days are observed in the arcuate structure. To the researchers’ curiosity, the bright area did not move with the wind behind the atmosphere, but remained stationary above a mountain on the surface of venus.

research team believes that this temperature is higher than the surrounding atmosphere of the bright area is caused by the lower atmosphere through the mountains above the gravity waves caused by the same as the earth’s air flowing through the mountains above the phenomenon. The team is still not clear whether the mountain terrain induced gravity waves can be uploaded to the cloud of Venus, and they are considering whether the new findings should be linked to the thick atmosphere of venus. As far as the observations are concerned, the atmospheric dynamics of Venus are much more complex than previously thought.
