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

Hubble portrait captures changes in Jupiter’s Great Red Spot
Scientists using the NASA/ESA Hubble Space Telescope have produced new maps of Jupiter that show the continuing changes in its famous Great Red Spot. The images also reveal a rare wave structure in the planet’s atmosphere that has not been seen for decades. This is the first in a series of annual portraits of the solar system’s outer planets which will help researchers study how they change over time.

Jupiter’s Great Red Spot heats planet’s upper atmosphere
Astronomers from Boston University have discovered that Jupiter’s Great Red Spot (GRS) may provide the mysterious source of energy required to heat the planet’s upper atmosphere to the unusually high values observed. Heating in Jupiter’s atmosphere 500 miles above the GRS is thought to be caused by gravity waves and acoustic waves creating turbulent atmospheric flows.
