Now that planet Saturn is effectively lost in the dusk twilight for UK-based observers, you may be wondering what has happened to the other four bright naked-eye planets. Far from disappearing, they have just transferred to the morning sky. From 8—11 October, the waning crescent Moon acts as a guide to Venus, Mars, Jupiter then Mercury in the eastern dawn sky.
Early risers wishing to see Venus as a dazzling ‘morning star’ need only glance low to the east in the pre-dawn sky. The planet reaches greatest brilliancy on Sunday, 20 September when, for a couple of mornings, it can be seen outshining brightest nighttime star Sirius in the southeast by a factor of seventeen times. Can you see your shadow cast by Venus?
As dawn creeps across Western Europe on the morning of Thursday, 10 September, a close conjunction of the two brightest objects in the nighttime sky is taking place low in the east an hour before sunrise. So, set your alarm for 5:30am in the UK to see a beautiful juxtaposition of a 26-day-old waning crescent Moon and dazzling planet Venus in the twilight.
