Great Red Spot.

Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. 45 years on, Voyager 1 and 2 continue to provide us with observations of the farthest reaches of space.

Our Voyager 1 spacecraft zoomed toward Jupiter in January and February 1979, capturing hundreds of images of Jupiter during its approach, including this close-up of swirling clouds around Jupiter's Great Red Spot.
