Jupiter’s Nice Crimson Spot is shrinking
Jupiter is a gas giant planet with an environment that teems with whorls and bands. Probably the most well-known characteristic on Jupiter is its stormy Nice Crimson Spot, which has raged on the planet for a whole bunch of years. It’s a counterclockwise-moving storm – an anticyclone – with winds as excessive as 300 miles (480 km) per hour. However the Nice Crimson Spot is shrinking. The storm we see in the present day is smaller and rounder than what observers photographed and sketched up to now.
Why has the Nice Crimson Spot lasted so lengthy? Nicely, with out floor options, the storms on Jupiter don’t encounter friction like on Earth. Anybody who lives by a mountain is aware of that such options could cause storms to dump rain on one facet after which dry up by the point they attain the opposite facet. There are not any such influences on Jupiter’s storms, so that they rage for many years and centuries.
So, why is the Nice Crimson Spot shrinking? Researchers aren’t certain. You’ll be able to learn extra about it here.

Pictures of Jupiter’s iconic storm from a whole bunch of years in the past
We don’t know precisely how lengthy individuals have seen the Nice Crimson Spot. Robert Hooke could have noticed it in 1664. However some individuals imagine he was taking a look at a special storm. Additionally, the Nice Crimson Spot we see in the present day could also be totally different from the storm observers noticed within the 1600s. Beneath is a portray from 1711 displaying the primary depiction of the Nice Crimson Spot as pink.
From 1831 to 1879, there are 60 recorded observations of Jupiter’s Nice Crimson Spot. From then on, observers have been repeatedly monitoring it. Beneath is a sketch from 1881, displaying how massive and rectangular it was at the moment.
More moderen observations
Listed below are extra comparisons of the Nice Crimson Spot – then and now – from photographic proof. From an commentary at Lick Observatory in 1891 (in Damian Peach’s publish), to the Pioneer 10 and Voyager flybys of the Seventies, you possibly can see for your self that the storm has shrunk and brought on a rounder look over time.
The Pioneer 10 pictures of Jupiter’s Nice Crimson Spot in 1973 had been dramatic, because the storm was LARGE, and RED, surrounded by whitish clouds. The GRS in the present day remains to be the biggest storm within the Photo voltaic system, however it’s now a shadow of its former glory. https://t.co/mTkoONz2GS pic.twitter.com/F0gYlZVWLv
