In the early 1600's Galileo was the first to use a telescope ( his own home-made model) to look at the heavens. Beginning in 1609, he became the first to see the mountains on the moon, the satellites of Jupiter ( four of them, at least) and Jupiter's big red spot. The spot is thought to be a giant hurricane, so it has been a storm that has lasted for a bare minimum of four hundred years.
The Great Red Spot on Jupiter is not visible to the naked eye from Earth. It requires a telescope to be seen clearly, as it is a massive storm located in Jupiter's atmosphere. While Jupiter itself can be seen without a telescope, the details of the Great Red Spot and other features become discernible only through telescopic observation.

Obviously it has not gone on "forever" , as that is an indeterminte amount of time and nothing lasts forever. Even the energy that resides in the universe itself will eventually fade & the universe will die. Jupiter's Red Spot however was first seen in 1831 ordescribed asa "permanent spot" as early as 1665 and 1713, so it has been anactive storm for at leastbetween 182 to 348 years.
The red spot is red and it is getting smaller.
The red spot on Jupiter, known as the Great Red Spot, has been observed for over 400 years. It was first documented in 1665 by Italian astronomer Giovanni Cassini.
Yes, have you ever seen a bug with a red spot on its back?
Because no other planet we have seen has a Great Red Spot?
The hurricane on Jupiter, call the Great Red Spot, may have been seen as early as 1664 or 1665, but the records are disputed. The first undisputed drawing of he Great Red Spot was made in 1831. It has likely existed for longer than that.
One unique characteristic of Jupiter is its Great Red Spot. The Great Red Spot is a strong storm, much like a hurricane, that can be seen in Jupiter's atmosphere.
About 300 years (109,500 days)

That is the planet Jupiter. The black spot was created recently when a asteroid collided with it. Jupiter has a Great Red Spot created through storms. No planet has a black spot no mars has a giant red spot and mercury has the black spot
3 times the size of earth there is also a little red spot and astronomers believe that the big red spot will eat up the little red spot.
The planet Jupiter is known to have a massive hurricane-like storm called the Great Red Spot raging for hundreds of years. It is a high-pressure storm system that is potentially the largest in the solar system.
The red spot is red and it is getting smaller.
Jupiter does have another red spot there is a little red spot about half the size as the great big spot cheers
