Boulder's Black Swift developing drone to study Venus' atmosphere

Although one Venusian rotation takes as much as 243 Earth days, its atmosphere charges much faster around the slowly spinning rock.

As a result, over one Venusian day duration days may increase by two minutes.

These constant and intense hurricanes affect the peaks on the surface of Venus that leads to the appearance in the atmosphere of stable structures and even affect the rotation of the planet. Venus, which spins in the opposite direction of Earth, has odd mountain ranges with the wind flowing in different directions.

Such waves, as Navarro explains, typically occur in the earth's atmosphere over a long and high mountain ranges, and exist for a relatively short time. It might be strong enough to actually shorten a Venusian day under extreme circumstances, according to a new planetary model developed by researchers from UCLA and University of Paris-Saclay in France in France. As a result of this supervisee having a wind whose speed reaches 400 kilometers per hour.

In addition to making Venus notoriously inhospitable to rover missions, the planet's thick atmosphere and the speed at which it moves may accelerate Venus's rotation, Science News reports.

The Japan Aerospace Exploration Agency has a spacecraft orbiting Venus called Akatsuki. When taking into account the presence of the waves, researchers discovered that it forces the lengths of days to change on Venus. In such circumstances, the existence of a stable gravitational waves would be impossible. But the more scientists observe it, the more surprises the second planet from the Sun throws at us. The scientists inferred that this peculiar atmospheric formation could be a faster moving "mountain wave".

Gravitational waves have also been able to spin the planet due to atmospheric pressure variations that they generate.

There are other things we don't know about Venus, too, which we could learn by figuring out the precise length of a Venusian day, according to the team.

This effect is minute, just a few minutes per Venusian day - but it could help explain previous discrepancies in measurements of Venus' rotation rate, such as a 2012 ESA study that found a 6.5 minute difference compared to a previous measurement.

Navarro and his colleagues found that gave rise to such discrepancies in the measurements of probe, studying another curious mystery of Venus - the mysterious "standing wave" with a length of 10 thousand kilometers, open probe "akatsuki" immediately after his arrival at the orbit of Venus in early 2016.
