Phys.org takes on Jupiter's Big Red Spot:

The largest and most powerful hurricanes ever recorded on Earth spanned over 1,000 miles across with winds gusting up to around 200 mph. That's wide enough to stretch across nearly all U.S. states east of Texas. But even that kind of storm is dwarfed by the Great Red Spot, a gigantic storm in Jupiter. There, gigantic means twice as wide as Earth.

With tumultuous winds peaking at about 400 mph, the Great Red Spot has been swirling wildly over Jupiter's skies for the past 150 years—maybe even much longer than that. While people saw a big spot in Jupiter as early as they started stargazing through telescopes in the 1600s, it is still unclear whether they were looking at a different storm. Today, scientists know the Great Red Spot is there and it's been there for a while, but they still struggle to learn what causes its swirl of reddish hues.

Understanding the Great Red Spot is not easy, and it's mostly Jupiter's fault. A planet a thousand times as big as Earth, Jupiter consists mostly of gas. A liquid ocean of hydrogen surrounds its core, and the atmosphere consists mostly of hydrogen and helium. That translates into no solid ground like we have on Earth to weaken storms. Also, Jupiter's clouds obstruct clear observations of its lower atmosphere. While some studies of Jupiter have investigated areas in its lower atmosphere, orbiting probes and telescopes studying the Great Red Spot can only see clouds scattered high in the atmosphere.

Amy Simon, an expert in planetary atmospheres at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said learning more about Jupiter and its Great Red Spot could help scientists understand Earth's weather system better. Jupiter's weather functions under the same physics as Earth, she said, just millions of miles farther from the sun. Simon also said Jupiter studies could improve our understandings of worlds beyond our solar system. "If you just look at reflected light from an extrasolar planet, you're not going to be able to tell what it's made of," Simon said. "Looking at as many possible different cases in our own solar system could enable us to then apply that knowledge to extrasolar planets."

    I thought it's all janrinok's fault. :-)
