The Sky This Week - Thursday August 23 to Thursday August 30
The Full Moon is Sunday, August 26. 4 bright unaided
eye
planets
can be seen in the evening sky. Venus is high in the
early evening sky coming close to the bright star Spica.
Jupiter is past
opposition, but is still big and bright in telescopes. Saturn
and Mars are visible in
the evening
skies. Mars is visited by the waxing Moon on the 23rd. Mars is just past opposition but is still bright and big
in even
small telescopes. There is a series of bright International Space Station passes this week.
The Full Moon is Sunday, August 26.
The ISS passes below Venus as
seen from Adelaide on the evening of Friday 24 August at 19:18 ACST.
Simulated in Stellarium (the ISS will actually be a bright dot), click to embiggen.
This week will see the International Space Sation return to the evening skies, with som e cole passes to the bright planet Venus between the 24th to 26th, as well as close passes to Mars and bright stars. This is very location dependent, so see my ISS pass page for details.
Evening twilight sky on Saturday August 25 looking west as seen from
Adelaide
at 19:16 ACST (90 minutes after sunset). Venus is high above the horizon and coming closer to Spica. Jupiter is now high in the western sky as well.
The insets shows simulated telescopic views of Venus as seen with a 5mm telescopic eyepiece and Jupiter on Wednesday the 29th as Ion, Ganymede and their shadows pass over Jupiter's face at 19:16 ACST .
Similar views will be seen throughout Australia at the equivalent local time (90 minutes after sunset, click to embiggen).
Brilliant Venus is visible high in the evening until well after full dark. Venus is visible to the unaided eye from before sunset, easy to see shortly after sunset and can viewed well after 90 minutes after sunset. During the week Venus moves further towards the bright star Spica and is passed by the ISS during the week.
Whole sky view of the evening sky on Saturday August 25 as seen from
Adelaide
at 19:16 ACST (90 minutes after sunset). Four bright
planets and the nearly full Moon are visible in the evening sky.
Similar views will be seen throughout Australia at the equivalent local time (just after 90 minutes after sunset, click to embiggen).
Evening
sky on Saturday August 25 looking east as seen from Adelaide
at 19:16 ACST (90 minutes after sunset). Saturn and Mars are
clearly visible with the waxing Moon below Mars. The
insets are simulated telescopic views of Saturn and Mars as seen with a 5mm telescopic eyepiece.
Similar views will be seen throughout Australia at the equivalent local time (90 minutes after sunset, click to embiggen).
Venus is readily visible above the horizon in the early evening. It is bright enough to be visible from just on sunset and to well past 90 minutes after sunset at full dark, when it is two and a half hand-spans above the horizon. During the week Venus moves closer to the bright star Spica and is passed by the ISS during the week.
Mercury is deep in the twilight in the morning skies and very difficult to see.
Jupiter is high in the early evening sky above the north-western horizon. It was at Opposition on the May 9th, and is still visible most of the night. It is a good telescopic object in the early to mid-evening and is setting just before midnight local time. There are some good Jovian Moon events this week. This week Jupiter moving away from the bright star alpha Librae (Zubenelgenubi).
Mars is in Capricornius and is readily seen in the evening. Mars was at opposition last month on July 27th, when it was biggest and brightest as seen from Earth. This was the best opposition since 2003. However Mars will remain bright and large in even small telescopes for some time. In a telescope you may see a few features as the huge dust storm sweeping the planet continues to subside. A guide to observing Mars at the time is at my Mars Opposition page. The Moon is close to Mars on the 23rd.
Saturn is now high in the northern evening sky in the early evening, and isa good telescopic object in the mid to late evening sky. It was at opposition, when Saturn is biggest and brightest as seen from Earth, on June the 27th. It is within binocular range of the Trifid and Lagoon nebulae. However the increasing Moon light makes seen these nebula more difficult.
