You are watching: How big is the great red spot on jupiter
Jupiter isn’t shedding its most well known feature at any time soon.
The planet’s great Red spot — which shows up as a prominent, flame-hued blemish on the gas gigantic — is a huge storm that has actually been churning ~ above Jupiter for centuries. Despite observations over the past decade that suggest the storm’s clouds room shrinking, researcher at the university of California, Berkeley, who have been examining the storm’s behavior with computer simulations currently say over there is no proof that the megastorm is dying.
“I would certainly take every one of that through a serial of salt,” said Philip Marcus, a professor of mechanical engineering at Berkeley. “We feeling confident that the sky is no falling."
Marcus and also his colleagues gift their study Monday in ~ the 72nd annual meeting of the American physics Society’s department of liquid Dynamics in Seattle.

The good Red Spot’s outlook was called into inquiry after pictures from May and June showed substantial red “flakes” sloughing turn off the storm. A 2018 NASA study also found the the megastorm, which currently measures an ext than 10,000 miles wide, has actually contracted due to the fact that 1878, when consistent observations the the spot began.
Observations from the 1800s suggested that Jupiter’s an excellent Red Spot was once more than 4 times the diameter that Earth, however now, the storm is just big enough come fit a little an ext than one planet inside it, follow to NASA. This triggered some scientists to wonder if the an excellent Red Spot to be on the verge the disappearing.
But Marcus said changes in the dynamics that the storm’s clouds likely betray the strength of the basic vortex.
“I was doubtful that measure clouds speak you about the underlying engine or vortex,” that said. “If one to be to examine climate adjust on Earth, you want to take a look at the clouds due to the fact that they’re indicating something, yet there’s a lot an ext going on than what’s in the clouds.”
Though the storm’s illustration has adjusted in the previous decade, an especially in the activity of the spot’s clouds, the researchers discovered no proof that the underlying vortex’s size or intensity has changed.
Marcus added that the molting observed earlier this year by amateur astronomers can be described by constant weather phenomena top top the planet.
The an excellent Red clues is well-known as one anticyclone, since the storm’s winds swirl approximately a center of high atmospheric press that makes it revolve opposite to just how hurricanes churn on Earth.
Marcus stated the flakes that were watched peeling off the storm in the spring coincided with monitorings of the great Red clues merging v what to be likely little anticyclones as well as a separate occurrence where the megastorm repelled and also deflected a adjacent cyclone.
As such, the flakes may have actually been “undigested lumps of merged anticyclones,” the said.
It’s assumed that anticyclones merge with each various other on Jupiter every few months, and also close encounters in between anticyclones and cyclones occur once every couple of years. Marcus said it’s not common for this two events to happen at the same time, yet maintained that once he and his team conducted simulations of this two events simultaneously, they to be able to recreate the conditions on Jupiter.
Gordon Bjoraker, an astrophysicist at NASA’s Goddard space Flight center in Greenbelt, Maryland, to be not associated with the brand-new research yet agreed the it’s unlikely the Jupiter’s specifying feature is facing any type of imminent threats.
The good Red clues is periodically likened to a wedding cake, and Bjoraker, who has performed extensive research on Jupiter’s atmosphere, said photos taken by amateur astronomers and also the Hubble room Telescope capture only the top and center layers.

“The good Red point out is giant thick,” the said. “There are changes to the optimal of the cake, however the base is still huge.”
And unequal shorter-lived storms on other planets, such as Neptune, wind currents top top Jupiter keep the great Red point out drifting east to west, rather than advertise it north or south, whereby polar or equatorial wind jets can tear the storm apart.
“If it doesn’t wander north or south, it’s no going come disappear,” Bjoraker said. “It’s remarkably stable.”
