The Sky This Week - Thursday October 12 to Thursday October 19
The Last Quarter Moon is Thursday, October 12. Jupiter is low in the twilight sky. Saturn is visible most of the evening in the heart of the Milky Way. Venus
is now very low in the morning twilight and forms a line with the crescent Moon and Mars on the 18th.
The Last Quarter Moon is Thursday, October 12.
Evening sky on Saturday October 14 looking north-west as seen from
Adelaide at 19:55 ACDST (30 minutes after sunset). Jupiter is very low above the
horizon, deep in the twilight.
Similar views will be seen elsewhere in Australia at the equivalent local time (30 minutes after sunset). (click to embiggen).
Jupiter is setting early evening and is above the western horizon in the twilight. You will need a clear level horizon to see it.
Opposition, when Jupiter is biggest and brightest as seen from Earth, was on April the 8th. Jupiter sets around 8:13 pm local daylight saving time. Jupiter is now too low to be a good telescopic target.
Mercury is lost in the twilight.
Evening sky on Saturday October 7 looking west as seen from Adelaide at 20:55 ACDST, 90 minutes after sunset.
The inset shows the telescopic view of Saturn at this time. Similar views will be seen elsewhere in Australia at the equivalent local time. (90 minutes after sunset, click to embiggen).
Saturn was at opposition on June the 15th, when it was biggest and brightest in the sky as seen from earth. Saturn is visible all evening long. Saturn is a good telescopic target from 9:00 pm daylight saving time until around 11 pm daylight saving time. It is poised next to the dark rifts in the Milky Way and is in a good area for binocular hunting. Although still high in the early evening sky, Saturn begins to sink into the western evening skies as the week progresses. Saturn's rings are visible even in small telescopes and are always good to view.
The constellation of Scorpio is a good guide to locating Saturn. The distinctive curl of Scorpio is easy to see above the north-western horizon, locate the bright red star, Antares, and the look to the left of that and slightly above, the next bright object is Saturn.
Morning sky on Wednesday October 18 looking east as seen from Adelaide
at 6:09 ACDST (30 minutes before sunrise). Venus is bright just above the
horizon and forms a line with the thin crescent Moon and Mars.
Similar views will be seen throughout Australia at the equivalent local time (that is 30 minutes before sunrise, click to embiggen).
Venus is lowering in the morning sky. This week Venus forms a line with the thin crescent Moon and Mars. It is becoming hard to see Venus in the early twilight, and you will need a clear unobstructed horizon to see the lineup low in the twilight.
Mars is climbing higher the twilight, but sound be reasonably (just) visible this week.
