Cosmic Tricks and Treats in October's Night Sky

Topic: Astronomy

NASA highlights four celestial events in October, including a disappearing planet, two meteor showers, and a bright full Moon. The events are visible to the naked eye or with binoculars. Jupiter disappears behind the Moon on October 6, while the Draconid and Orionid meteor showers peak on October 8-9 and 21.

October is bringing a spectacular lineup of celestial events that can be seen in the night sky without any special equipment. NASA has highlighted four events worth watching this month.

Jupiter Disappears Behind the Moon on October 6 Before sunrise on Tuesday, October 6, skywatchers in parts of North America had an opportunity to witness an unusual celestial disappearing act. Jupiter, the largest planet in our solar system, slipped behind the Moon's slender crescent and remained hidden for approximately an hour before coming back into view. Astronomers call this phenomenon a lunar occultation.

Draconid Meteor Shower Peaks October 8 and 9 The next celestial attraction comes on the evening of Thursday, October 8, when the Draconid meteor shower reaches its peak. Favorable viewing begins around 9 p.m. EDT, and the display continues into the early hours of Friday, October 9.

Orionid Meteor Shower Brings Debris From Halley's Comet Another opportunity to catch shooting stars arrives on October 21, when the Orionid meteor shower reaches its annual peak. These meteors have a particularly fascinating origin. They are tiny fragments of material left behind by Halley's Comet during its journeys through the solar system.
