The great red spot, This is the great red spot

Now zarkasi.com will share about the great red spot do you know what's the great red spot ? A large red dot is a gigantic storm, rotating in Jupiter's atmosphere. It's like a hurricane on Earth, but much larger. Jupiter's Great Red Spot is greater than twice the size of Earth! In this storm's winds around 270 miles per hour. No one knows when the first big red dot appeared on Jupiter, but has been seen in Jupiter since people started to look through the telescope 400 years ago.

a large red dot is an area of ​​high pressure continuously, causing anti-storm field at the planet Jupiter, 22 degrees south of the equator. It has been continuously observed since 187 years, since 1830. It is believed that the earlier observations from 1665 to 1713 is the same storm, if this is true, he has discovered more than 350 years. [1] [2] and storms like this are not common in the volatile atmosphere of the gas giant.

Perhaps there is a large red dot (planting) since before 1665, but visible to the current point for the first time after 1830 and researched only after a prominent appearance in 1879. The long gap separating the current study period after 1830 of the discovery of the seventeenth century , if this is running the original place or reshaped, either faded, or even if the simple log monitoring is simple, the whole is not known. [3]

For example, often credited vision first Robert Hawke, who described the place on the planet Earth in May 1664, but it is possible to find a hook located on the belt that one really (north equatorial belt, compared with the Great Red Spot the current location in the south of the tropical belt). Much more convincing is the description of "permanent place" Giovanni Cassini in the next year. [4] with fluctuating vision, observe where Cassini from 1665 to 1713, but the gap 118 year observational make the identity of the two eyes can not be inferred, a shorter history of watching the slow motion of the oldest and modern place to establish their identity unlikely. [5]

Ambiguity is simple to place Jovian filmed in 1711 canvas by Donato Kreta, which was presented at the Vatican. [6] [7] part of a series of panels in which the heavenly bodies are (large) are different as the background of various scenes of Italy, all overseen by the astronomer Joostashiw Manfredi for accuracy, plate Crete was the first to describe red plantings. It is worth mentioning is the fact that he has not been officially explained every red Jovian profits before the end of the 1800s. [7]
A broader view of the buyer large red spots as seen from Voyager 1 in 1979

February 25, 1979 [8] when the spacecraft Voyager 1 9.2 million kilometers (5.7 million miles) from Jupiter, transmitted the first detailed images of the Great Red Spot to the ground. The small details of clouds, about 160 km (100 miles) through the visible. Cloud colorful patterns, wavy look to the left (west) the red dot is an area of ​​complex waves and movement vary greatly.

In early 2004, the Great Red Spot is nearly half lengthwise century ago, when it reached a size of 40,000 km. At current rates of decline will become circular by 2040, although this is not possible due to the effect of distorting the jet stream neighbors. It is not known how long it will continue, or whether the change is the result of normal fluctuation. [9]

A smaller place, assigned to Oval BA, formed recently (March 2000) from the merger of three white ovals, [10] [11] turns into a reddish color. Astronomers Ptbrigadha in little red dots or red, child. As the June 5, 2006, shows that the Great Red Spot and Oval BA close to convergence. [12] storms pass each other every two years, but it was not between 2002 and 2004 of little significance. It is estimated that Amy Simon Miller of NASA's Goddard Space Flight Center, the storm is closer to 4 July 2006. I worked with Phil Emek de Pater and Marcus of the University of California at Berkeley, and a team of professional astronomers since April 2006 to study storms using the Hubble Space Telescope ; on July 20, filmed Alaoasftin to pass each other with the Gemini observatory without convergence. [13] In May / May 2008 the third storm turned red. [14]

It should not be confused with the Great Red Spot major dark spot, a feature observed near the North Pole to the buyer in 2000 by the spacecraft Cassini-Huygens. [15] Note that the gain in the atmosphere of Neptune is also called a large dark spot. This last feature filming by Voyager 2 in 1989, and may be a hole in the atmosphere instead of the storm and nothing else until 1994 (although the same spot appears far from the north).
