For nearly 200 years, scientists have wondered about the Giant Red Spot on Jupiter. This week, pictures of the planet show dark clouds moving around, and through, a
These are the closest images humans have ever seen of the spot, on the giant gas planet.
America's space agency NASA, sent the Juno spacecraft to Jupiter to gather scientific data on the solar system's biggest planet. On Monday Juno flew over the Giant Red Spot, which is a storm larger than our planet Earth.
First observed in 1830, scientists think it may be more than 350 years old. The storm measures 16,350 kilometers wide and appears to be getting smaller.
"For hundreds of years scientists have been observing, wondering and theorizing about Jupiter's Great Red Spot," said Scott Bolton. He is the Juno principal investigator from the Southwest Research Institute in San Antonio, Texas.
Bolton said it will take time for the scientists to process the information Juno is sending back to Earth. "Now we have the best pictures ever of this iconic storm. It will take us some time to analyze all the data from not only JunoCam, but Juno's eight science instruments, to shed some new light on the past, present and future of the Great Red Spot."
NASA hopes the information will also tell them what is underneath the storm.
James O'Donoghue is a scientist at NASA Goddard Space Flight Center near Washington DC. He told VOA Learning English in an email that scientists could see "more detail than we ever have before" in these new images.
He said, "What we are finding is that the closer we look, the more wild it looks!"
O'Donoghue explained that this storm is "a great deal more complex" than a regular storm system, with smaller storms inside itself. "There are rich colors that indicate a complex three-dimensional sense," he added. That is because "some parts of the storm are towering above others, much like storms at Earth tower above the surface."
Juno was launched on August 5, 2011 from Cape Canaveral in Florida. The spacecraft will continue flybys to get more information for scientists to learn about the planet.
