Let’s search for the naked-eye planets for this week. Venus can be spotted low in the west-northwest twilight by 10 pm or a little after. Venus will set at 11:07 pm. Mars can be found in the west-northwest at 11pm, It’s in Cancer and is currently passing in front of the Beehive star cluster which can be spotted in a pair of binoculars. Mars will set at 11:38 pm as it is slowing losing its race with the Sun. Saturn and Jupiter, are in the morning sky. Saturn will actually rise before midnight at 11:44 pm. It’s seen with the stars of Capricornus. Brighter Jupiter, to the left of Saturn, will rise at 12:34 am. By 5 am, these two planets will be in the south and south-southeast in the morning twilight.
