Astronomy Highlights

October nights lengthen, welcoming a great view of the Milky Way arched from southwest to northeast, its subtle beauty anchored by the Summer Triangle in the southwest, and the rising star Capella in the northeast. Saturn sinks low into the southwest through the month, but it is the predawn skies where the planets are offering a wonderful assortment of views. Venus starts as the highest of a trio including Mars and Jupiter, but through the month, Venus gets lower, passing Jupiter and Mars during the last week.

8-9 – The mornings host a waning Crescent Moon sliding past Venus on the 8th, and then to the right of Mars and Jupiter on the 9th, near 6 AM EDT.

16 – Low in the southwest this evening from 6:45 to 7:00, the Crescent Moon shines above Saturn (lower right), and the red star Antares (lower left).

20 – The Orionid Meteor Shower continues over the next four nights, fragments of Halley’s Comet, producing some 20 meteors per hour.

25 – Venus and Jupiter are side-by-side in the early morning skies, about one third of the way up from the horizon at 6:00 AM EDT.
