Oval BA, or more commonly recognized as the Little Red Spot of Red Spot Jr., has captured some scientists’ attention. Still wondering what Oval BA is? It is a fierce storm on the planet Jupiter. Oval BA is the little “brother” to the well-known Great Red Spot on Jupiter.

Jupiter facts

Jupiter is the fifth planet from the Sun and is the largest planet in our solar system. To give you an idea of how massive Jupiter is, one thousand planets the size of Earth could fit inside one Jupiter!

The Great Red Spot is a huge storm circulating counterclockwise in Jupiter’s atmosphere. Oval BA is about half the size of the Great Red Spot. Oval BA first appeared in 2000 when three smaller spots collided.

What is going on with Oval BA?

Recently the Hubble Space Telescope relayed information detailing Oval BA has changed and is becoming more like the Great Red Spot. A year ago, Oval BA was white. Currently it is a reddish hue matching that of its bigger counterpart. Oval BA has been clocked having 400 mile per hour winds.

Scientists speculate the little red spot has gained speed as well as strength as it has shrunk. Amy Simon-Miller, NASA planetary scientist, explained Oval BA picked up steam in the same fashion spinning figure skaters accelerate when they move their arms closer to their core. The reddish hue can be attributed to red material in the atmosphere-mostly sulfur.

Jupiter will be heading behind the sun out of Earth’s view until January. Scientists are expecting more noticeable changes when Jupiter comes back into view.

Until then, what do you think will happen to these two distinct storms? Do you think there will be a day when Oval BA and the Great Red Spot collide and create one massive storm?

It may indicates a general rise of temperatures, which has this effect on the storms. just like when you're boiling a soup. when cold, you see many oil spots. when hot, those oil spots merge.
there are also rumours and prophecies about jupiter igniting to a new, second sun in our solar system...

I think sometime the storms have to collide. The winds and the surrounding winds will eventually pull together and collide. Its like two black holes or two galaxies. It will just take time to collide.
