A series of images captured by NASA’s Hubble Space Telescope have revealed subtle changes on Jupiter, including a unique filamentary feature in the planet’s famous Great Red Spot. And you can see it all in glorious 4K.

NASA says it constantly snaps images of distant planets to give scientists a better understanding of how features such as winds, clouds, atmospheric chemistry and more change planets over time. The latest imagery revealed a “rare wave” at Jupiter’s equator, along with changes occurring within the planet’s massive storm, which scientists believe has been waging on for hundreds of years (and is about the size of three Earths).

“Every time we look at Jupiter, we get tantalizing hints that something really exciting is going on,” said Amy Simon, a planetary scientist at NASA’s Goddard Space Flight Center.

According to the images, NASA has confirmed that Jupiter’s Great Red Spot is indeed shrinking—by as much as 150 miles on its long axis compared to a year ago. Scientists also describe the storm as emitting more of an orange color, not red, while its core has faded in color over the past several years. As for that unique filament seen in the core, NASA says it can be seen getting twisted by winds as high as 330 miles per hour in the sequence above.
