The Sky This Week - Thursday May 24 to Thursday May 31
The Full Moon is Wednesday, May 30.
Similar views will be seen throughout Australia at the equivalent local time (60 minutes after sunset, click to embiggen).
Venus is now high in the late twilight. 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 to the left is a simulated telescopic view of Jupiter and its moons at 23:45 ACST, on the 26th with Io passing across the face of Jupiter. The inset to the right is a simulated telescopic view of Saturn and the globular cluster M22.

Vesta is now bright enough to be easily seen in binoculars. It is travelling through 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.
Similar views will be seen throughout Australia at the equivalent local time (30 minutes before sunrise).
Venus is now sufficiently high in the evening twilight to be readily visible above the horizon. It is nearly 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.
Venus s close to the brightish star Metsuba on May 28.
Mercury is rapidly heading towards the horizon. This is the last week that it is readily observable in the morning sky and is the brightest object above the eastern horizon.
Jupiter is rising in the early evening as Venus is setting. It was at Opposition on the 9th, and is still visible all night long. It is a good telescopic object in the late evening. There are some good Jovian Moon events this week. Over the week Jupiter comes closer to the bright star alpha Librae (Zubenelgenubi) and is close on the 27th and 28th, when the waxing Moon visits Jupiter.
Mars is in Sagittarius the archer and is now rising in the late evening. Mars is moving away from Saturn although the pair are still obvious. Mars is brightening ahead of opposition later this year.
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 May 31.
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.
