NASA’s Juno spacecraft now orbiting Jupiter is equipped with instruments designed to study the giant planet’s interior. But it also carries a public-outreach camera known as JunoCam that sends back imagery that is processed by citizen scientists. Gerald Eichstädt and Seán Doran have combined to produce stunning views of Jupiter, including this image captured by Juno after its 12th close approach, providing a unique view showing the Great Red Spot in all its glory as if it’s in the northern hemisphere. The raw imagery was captured on 1 April over a span of about 32 minutes at altitudes between 17, 329 and 68,959 kilometres (10,7678 and 42,849 miles). The image is a composite of several shots that NASA says were “re-projected, blended and healed.”
The existence of a fifth giant gas planet at the time of the solar system’s formation — in addition to Jupiter, Saturn, Uranus and Neptune that we know of today — was first proposed in 2011. Now astrophysicists at the University of Toronto have found that a close encounter with Jupiter about four billion years ago may have resulted in the fifth giant planet’s ejection from the solar system altogether.
