Watch the king of the planets turn on its throne

Making its fifth science pass close to Jupiter’s turbulent cloud tops, NASA’s Juno spacecraft sailed by the Solar System’s king planet Friday to collect another treasure trove of data on the giant world’s atmosphere, internal structure, and magnetic field.

Currently the third brightest celestial object in the night sky of the British Isles after the Moon and Venus, Jupiter presents a cornucopia of phenomena for observers with medium to large telescopes tonight.

As dusk fades to dark on Sunday, 17 April, observers in the British Isles should look up to the southern sky to see the 10-day-old waxing gibbous Moon and Jupiter just four degrees apart, within the same binocular field of view. Jupiter’s largest moon, Ganymede, and second Galilean moon, Europa, provide some events for telescope owners to view at higher magnifications.
