The Sky This Week - Thursday May 31 to Thursday June 7
The Last Quarter Moon is Thursday, June 7. The Moon is at Apogee, when it is furthest from the Earth, on June 3.
Similar views will be seen throughout Australia at the equivalent local time (60 minutes after sunset, click to embiggen).
Venus is now visible in the early evening. Venus is visible to the unaided eye from sunset, easy to see 30-60 minutes after sunset and can viewed up to 90 minutes after sunset.
The inset is a simulated telescopic view of Jupiter and its moons at 18:27 ACST, on the 3rd with Europa and its shadow passing across the face of Jupiter.

Vesta is now bright enough to be easily seen in binoculars. It is travelling past the northern edge of the open cluster M24 heading towards the open cser M23. It is brighter than most of the stars in the cluster, but you may need to watch over several nights to watch it move.
Venus is readily visible above the horizon. It is over two hand-spans above the horizon 60 minutes after sunset. It is bright enough to be visible just after sunset and easy to see up to 60 minutes after sunset. Venus can be viewed for at least 90 minutes after sunset if you have a flat, unobstructed horizon.
Mercury is no longer visible i te twilight glow, and will return to the evening skies mid June.
Jupiter is rising in the early evening as Venus is setting. It was at Opposition on the 9th, and is still visible most of the night. It is a good telescopic object in the mid to late evening. There are some good Jovian Moon events this week. Over the week Jupiter is within a finger-width of the bright star alpha Librae (Zubenelgenubi).
Mars is in Capricornius and is now rising in the late evening. Mars is moving away from Saturn and brightening ahead of opposition later this year. The waning Moon is close to Mars on the 2nd and 3rd.
Saturn is climbing higher the evening sky, although telescopically it is still best in the morning sky. It is within binocular range of several attractive clusters and nebula. It is close to the bright globular cluster M22 and the pair are visible in binoculars and wide field telescope eyepieces. Saturn is close to the Moon on the1st and 2nd.
The asteroid Vesta is now bright enough to be easily seen in binoculars. It is travelling along the northern edge of the open cluster M24. It is brighter than most of the stars in the cluster, but you may need to watch over several nights to watch it move and be sure of its identity. Printable spotters chars are here.
