Experts from
the Rikkyo University in Tokyo have found a HUGE structure located within the
atmosphere of our neighboring planet Venus, using the Akatsuki spacecraft.
According to reports, the structure is THOUSANDS of kilometers across.

Interestingly,
it wasn’t there last time we looked. The massive structure stretches over 10
kilometers in the cloud tops in Venus’ upper atmosphere. What caused confusion
among experts is the fact that the ‘structure’ did not move for several days,
and remained stationary over a mountainous region on the planet’s surface.
VENUS IS
just a weird planet. “With Venus and Earth, it’s like you had two chocolate
cake mixes and ended up with one chocolate cake and one lemon cake,” says Ellen
Stofan, NASA’s former chief scientist.
Scientists
managed to spot the structure in the infrared image taken by the Akatsuki
spacecraft from December 7 and 11, 2015. Akatsuki entered orbit around Venus on
the 7th of December of 2015, five years behind scheduled as the spacecraft
failed to enter orbit in 2010.
So what’s up
with the structure? Must be aliens right?
Well, at the
moment, the exact properties of the structure aren't clear at all. However,
aliens may not be the answer we are looking for as scientists suggest that the
most likely explanation is that the structure is most likely the result of some
sort of wave generated as air flowed over a mountain nearby, from high to low
temperature, aka Gravity Wave.
Images taken
over four days from Akatsuki showed the wave staying in roughly the same place.

As the
article at IFLScience explains, a westerly wind blows up to 60 times faster
than the planet’s rotation, reaching speeds of more than 360 kilometers per
hour (225 miles per hour). Interestingly this was one of the main reasons why
scientists were a bit confused. As Taguchi noted, it is extremely surprising
that the structure managed to maintain its position over a couple of days.
Interestingly,
as wired.com points out, prior to this study, scientists didn't believe gravity
waves could propagate this high up into the atmosphere, thinking they’d be
confined to the lower atmosphere.
The Study
was published in the journal nature: Large stationary gravity wave in the atmosphere of Venus.

“We suppose
that Highlands are a key to generating the stationary gravity waves because
most of the bows—and we have found more than 15 bows so far—have appeared above
the Highlands at their centers,” Makoto Taguchi from Rikkyo University says.
Speaking to
IFLScience, Taguchi: “This is the first evidence of gravity wave propagation
from the lower atmosphere to the middle atmosphere [of Venus].”
As the
article at IFLScience explains, a westerly wind blows up to 60 times faster
than the planet’s rotation, reaching speeds of more than 360 kilometers per
hour (225 miles per hour). Interestingly this was one of the main reasons why

that the structure managed to maintain its position over a couple of days.
“There may exist
a mechanism of gravity wave generation like a mountain wave or a thermal tide,
which are found in the terrestrial atmosphere,” he said. “To answer this
question we need more data that covers all local times and longitudes.”
