Orionid Meteor Shower This Weekend
http://www.wired.com/images_blogs/wiredscience/2012/10/Orionid12n.jpeg
One of the most spectacular night-sky shows will kick into high gear this weekend when the Orionid meteor shower peaks early in the morning on Oct. 20. It will continue to dazzle until just before dawn on the 21st.
The Orionids are cosmic leftovers — bits of rock and ice that remain behind from Halley’s comet, which last passed through the inner solar system in 1986. As the sun heated the famous comet, chunks of debris broke off, leaving a trail of material that the Earth passes through annually. The pieces hit the Earth’s atmosphere at 148,000 mph, burning up and leaving trails that sometimes shine green or orange.
Conditions for this year’s shower should be very promising, with the sliver of a first-quarter moon setting around midnight, leaving the night sky exceedingly dark. To watch the meteors, you can take a nice warm blanket out to an area far from city lights, like a state park, and lie back to get a good full-sky view. You can expect around 25 meteors to shoot overhead per hour during the shower.
