The Juno spacecraft in orbit around Jupiter’s poles continues to send back jaw-dropping views of the giant planet’s turbulent atmosphere, including this down-the-throat look into a 2,000-kilometre-wide (1,200 miles) cyclonic storm at 49 degrees north latitude. Jupiter is composed mostly of hydrogen and helium, but some of the colour in the clouds seen here may be the result of sulphur and phosphorus gases rising from the warmer interior. Citizen-scientist Kevin M. Gill processed this image, captured by the Junocam instrument on 3 November at an altitude of about 8,500 kilometres (5,300 miles) during Juno’s 23rd close flyby.
On Saturday 27 August at 22:32 UT (11:32pm BST), a spectacularly close conjunction occurs between Jupiter and Venus just 22 degrees west of the Sun in the constellation of Virgo, when the planetary pair are just 4 arcminutes, or one-fifteenth of a degree, apart. Here is our guide to the best locations and times to view this rare event.
NASA’s Juno spacecraft made a high-speed pass less than 3,000 miles over Jupiter’s turbulent clouds Thursday, taking dozens of pictures, measuring radiation and plasma waves, and peering deep inside the planet’s atmosphere, but officials still have not cleared the orbiter’s main engine for a planned maneuver to position the probe for improved science observations.
A four-planet system orbiting the star Kepler-223 in the constellation Cygnus is actually a rarity: Its planets, all miniature Neptunes nestled close to the star, are orbiting in a unique resonance that has been locked in for billions of years. For every three orbits of the outermost planet, the second orbits four times, the third six times and the innermost eight times.
