why is there a red spot on jupiter
How many of the in our can you by? A few of them are
fairly. For example, most everyone knows what Earth looks like. Some believe it resembles a blue marble because of the amount of Earth's surface covered by water. Many people can also because of its red color. Likewise, 's rings make it to remember. Those who know what Jupiter looks like often recognize it when they see its Great Red Spot. Why does Jupiter have a Great Red Spot? Did it get sunburned? Did alien visitors spill something? Could it be an ocean filled with cranberry juice? None of those farfetched ideas come close to the, which is that Jupiter's Great Red Spot is a storm. Jupiter's Great Red Spot makes Earth's storms look by. The largest, most powerful storms ever recorded on Earth have been massive that stretch across 1,000 miles with winds reaching 200 miles per hour. The Great Red Spot stretches about 1. 3 times the size of Earth with winds that can reach maximum speeds of up to 400 miles per hour! The storm has been on Jupiter for at least 150 years and possibly as long as 400 years or more.
In, Earth's longest storm, Hurricane John in 1994, lasted 31 days. How can such a large storm rage on and on for so long? The Great Red Spot's is a factor of Jupiter itself. Jupiter is about 1,000 times larger than Earth, but it consists mostly of gas. That means there's no like we have on Earth to a storm. The Great Red Spot has also lasted much longer than other storms on Jupiter because it's located between two powerful jet streams that move in opposite directions. Scientists claim the storm is like a spinning wheel caught between belts moving in opposite directions. Despite its, the Great Red Spot has been shrinking steadily. In the late 1800s, the Great Red Spot was about four times the size of Earth. By 1979, when the Voyager 2 flew past Jupiter, the storm had shrunk to about twice the size of Earth. Today, the Great Red Spot is about 1. 3 times the size of Earth. Some scientists believe that it will continue to shrink and could disappear within the lifetimes of today's youth.
With help from new photographs and data from NASA's Juno, scientists continue to study Jupiter and its Great Red Spot today. Some scientists are still trying to figure out why the storm is red. The most popular current theory is that cosmic rays or ultraviolet radiation from the Sun are reacting with ammonium hydrosulfide in Jupiter's atmosphere. The iconic Great Red Spot of Jupiter may disappear in the next 20 years, according to a researcher at NASA s Jet Propulsion Laboratory (JPL) in California. The massive storm larger than Earth itself was, and observations from the 1600s also revealed a giant spot on Jupiter s surface that may have been the same storm system. This suggests Jupiter s Great Red Spot (GRS) has been raging for centuries. , Business Insider spoke with Glenn Orton, a lead team member and planetary scientist at NASA Jet Propulsion Laboratory (JPL), about the giant storm s fate. [ According to Orton, the storm s vortex has maintained strength because of Jupiter s 300-400 mph (483-640 km/h) jetstreams, but like any storm, it won t go on forever.
In truth, the GRS has been shrinking for a long time, Orton. The GRS will in a decade or two become the GRC (Great Red Circle), Orton said. Maybe sometime after that the GRM, by which he means the Great Red Memory.

That works out to more than 35,000 miles four times the diameter of Earth. When the nuclear-powered spacecraft Voyager 2 in 1979, however, the storm had shrunk to a bit more twice the width of our own planet. Data on Jupiter s crimson-colored spot reveals that this shrinking is still occurring. As of April 3, 2017, the GRS spanned the width of 10,159 miles (16,350 kilometers), less than 1. 3 times Earth s diameter. The longest storm on Earth, but Jupiter can sustain longer storms because the gas planet has tens of thousands of miles of atmosphere, and than Earth. Follow Doris Elin Salazar on Twitter.
