Jupiter may be best known for its "eye", also known as the Great Red Spot, but this is just one of many huge spots on its surface. Now the eye has been supplemented by a new surface feature that was discovered by an amateur astronomer.
The famous big red spot can be seen in the top left of the picture, and in the middle is the new feature that has not been observed before. It was first discovered by Clyde Foster of Centurion, South Africa, who noticed it when he viewed Jupiter through his telescope with a filter that was sensitive to the absorption of methane gas. Two days later, on June 2, NASA's Juno spacecraft flew near the area and was able to map the location in minute detail. The feature was named "Clyde’s Spot" in honor of its discoverer.
This image from NASA's Juno spacecraft captures several storms in Jupiter's southern hemisphere. Some of these storms, including the Big Red Spot in the upper left, have been stirring up the planet's atmosphere for many years, but when Juno received this view of Jupiter, the smaller, oval feature in the center of the picture was the New brand.

NASA's Juno team believes that the point is a cloud of material that breaks through the upper layers of the atmosphere and occurs regularly in that particular latitude.
This image was created by civil scientist Kevin M. Gill using JunoCam data from the Juno spaceship. Members of the public can download raw JunoCam images and do their own image processing. You are invited to upload your pictures to the Juno website.
According to NASA, Gill’s image above is “a map projection that combines five JunoCam images that will take place on June 2, 2020 between 3:56 am PDT (6:56 am EDT) and 4:25 am PDT (7:25 am) Clock EDT). . At the time the pictures were taken, Juno was between 45,000 and 95,000 kilometers from the planet's cloud cover in latitudes between 48 and 67 degrees south. "
The Juno spacecraft was launched in 2011 and reached orbit around Jupiter in 2016. In its day, it had to do some dramatic maneuvers to keep its mission going. The original plan was to only operate it until 2018. With its extended lifespan, the mission continued to collect data about Jupiter, including information about its atmosphere, composition, and chaotic magnetic field.
