One of the largest objects in the Asteroid Belt, (3) Juno, comes to opposition on 2 April, when it lies directly opposite the Sun as seen from Earth, and is at its brightest – albeit still only visible through telescopes.

Juno peers into the depths of a titanic jovian storm system

The Juno probe’s public-outreach camera routinely captures stunning views of Jupiter cloudtops and storms, including the Great Red Spot, seen here in an image processed by graphic artist Seán Doran. The GRS has been shrinking for years, but it remains easily the largest storm in the solar system and one still worthy of its name.

Jupiter’s intense northern and southern lights, or aurorae, behave independently of each other according to a new study using NASA’s Chandra X-ray and ESA’s XMM-Newton observatories.

Jupiter’s aurora presents a powerful mystery

9 September 2017 Astronomy Now

Scientists on NASA’s Juno mission have observed massive amounts of energy swirling over Jupiter’s polar regions that contribute to the giant planet’s powerful aurora – only not in ways the researchers expected.

First close up Juno images of Jupiter’s Great Red Spot reach Earth

12 July 2017 William Harwood

Two days after NASA’s Juno spacecraft streaked over Jupiter’s Great Red Spot, pictures of the solar system’s largest, most powerful storm, have been transmitted to Earth, giving eager scientist close-up views of the 10,000-mile-wide anticyclone where 400-mph winds have been howling for at least 187 years and possibly much longer.

Earth-based views of Jupiter to enhance Juno flyby
