Jovian moon shadow

27 October 2017 Astronomy Now

Jupiter’s moon Amalthea casts a shadow on the gas giant planet in this image captured by NASA’s Juno spacecraft. The elongated shape of the shadow is a result of both the location of the moon with relation to Jupiter in this image as well as the irregular shape of the moon itself.

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

Telescopes in Hawaii have obtained new images of Jupiter and its Great Red Spot, which will assist the first-ever close-up study of the Great Red Spot, planned for July 10.

First quarter Moon meets Jupiter and Spica in the evening sky

30 June 2017 Ade Ashford

Observer’s in the UK and Western Europe should look low to the southwest an hour after sunset on Friday, 30 June to glimpse the almost first quarter Moon a low-power binocular field of view to the right of Jupiter in bright twilight. The following night finds the waxing gibbous Moon forming a near isosceles triangle with the planet and first-magnitude star Spica in Virgo.

Jupiter’s “String of Pearls”

This enhanced-color image of Jupiter’s bands of light and dark clouds was created by citizen scientists Gerald Eichstädt and Seán Doran using data from the JunoCam imager on NASA’s Juno spacecraft.

Seeing double in the summer sky

24 June 2017 Ade Ashford

With astronomical twilight lasting all night around the Northern Hemisphere summer solstice for stargazers in the UK, what does the deep-sky observer do when the sky never gets truly dark? Fortunately, there are many beautiful double and multiple stars to seek out while most nebulae are off limits.

See the Moon hide double star Porrima then get close to Jupiter on 3—4 June

2 June 2017 Ade Ashford

Jupiter now lies highest in the UK sky at sunset, but the Solar System’s largest planet and its four bright Galilean moons still provide plenty of observable events during June, as we reveal. If you’re uncertain which evening ‘star’ is Jupiter, the Moon conveniently passes by on the night of 3—4 June, a time when European skywatchers can also see the Moon occult (hide) bright double star Porrima.
