New month = new skywatching guide 👻

Make sure to bundle up, and find a safe, dark spot away from bright lights because October has a lot to offer in the night sky. Starting off, the giant planets Jupiter and Saturn are visible throughout the night in October. Early in the evening, you'll find them to the southeast, moving slowly westward with the stars over the course of the night.

Looking to spot the full Moon? Our lunar companion will be in full illumination starting on Oct. 9 and will appear full for about three days. As the full moon after the Harvest Moon, this will be the Hunter's Moon, named that because historically during this period the harvesters have finished reaping the fields, allowing hunters easier sight of the animals that have come out to feed.

Next up, Mars has been steadily moving through the sky in an eastward fashion all year, but at the end of October, Mars halts this apparent motion and then appears to reverse course. From November to late January, Mars is in retrograde. About every two years, Mars appears to change its direction—an illusion caused by the motion of our planet in its orbit passing by the Red Planet in its orbit.

Lastly, look to the skies for a beautiful show throughout October and November as the Orionid meteor shower is active, peaking on the night of Oct. 20. Expect the shower to produce 10-20 meteors per hour at its peak, under clear, dark skies. This year, the Moon will be about 20% full on peak nights so it will interfere slightly but shouldn’t totally spoil the show—best of all, you can observe the meteor showers without any special equipment.

Between the planets, the dark black visual of the night sky is tinted in hues of navy blue with speckles of stars throughout.
