NASA’s Juno mission to Jupiter has now successfully executed a 10.5-hour propulsive maneuver. It’ll keep Juno – a solar-powered spacecraft – out of a mission-ending shadow due to have been cast by Jupiter onto the craft in November.
Jupiter’s moon Io is the most volcanically active world in our solar system. The Juno spacecraft – now orbiting Jupiter – has now gazed across a distance to acquire new images and insights about the “fires of Io.”
Scientists used Juno spacecraft data and models of how Jupiter’s inner core should look to probe the giant planet’s early history. They now think an object with 10 times Earth’s mass might have struck Jupiter billions of years ago.
Jupiter’s Great Red Spot is a giant storm, the largest known in our solar system. It’s been seen through earthly telescopes for more than 300 years. Lately, it’s been showing signs of breaking apart. Is this the beginning of the end for the beloved Spot?
Opposition on June 10 marks the middle of the best time of year to see Jupiter. The planet shines at its brightest best in Earth’s sky. It’s also out all night long, rising at sunset and setting at sunrise.
Triton is Neptune’s largest moon. It’s a bizarre and geologically active world – a possible ocean moon – visited by Voyager 2 in 1989. Now, NASA has proposed a new mission called Trident to sweep past Triton again in 2038.
Uranus and Neptune – the ice giants of the solar system – are distant worlds last visited by the Voyager 2 spacecraft in the late 1980s. But the Hubble Space Telescope is still keeping an eye on them and their dynamic atmospheres.
This new Juno spacecraft image shows magnificent swirling clouds in Jupiter’s dynamic atmosphere. The craft was about 4,400 miles (7,000 km) from the planet’s cloud tops on October 29, over about 40 degrees north.
