A meteor shower spawned by the remains of a comet will be at its best tonight, but whether the "shooting star" display will peak as amazing celestial fireworks or a cosmic fizzle remains to be seen.
The annual Draconid meteor shower will peak overnight tonight (Oct. 7 and 8) in the first of two substantial fall meteor displays in October. Astronomer Tony Phillips of the night sky observing website Spaceweather.com said the Draconids are "notoriously unpredictable," but worthy of a look by observers with dark, clear skies tonight.
"Northern-hemisphere sky watchers should be alert for slow-moving meteors emerging from the head of the constellation Draco the Dragon (not far from the North Star) on Sunday night, Oct 7th, through Monday morning Oct. 8th," Phillips wrote in weekend skywatching alert.
The Draconid meteor shower is created each year when the Earth passes through a trail of dust left over by the comet 21P/Giacobini-Zinner, an icy solar system wanderer that orbits the sun once every 6.6 years.
In 2011, the Earth passed through a dense patch of comet debris and spawned an impressive Draconid meteor shower for some lucky observers, with up to 600 meteors per hour that - while faint - were still amazing, Phillips explained via Spaceweather.com. But last year's display may have been disappointing for observers in North America since it peaked during daylight hours, with the nighttime observing period spoiled by the bright moon.
Phillips said there is no reason to expect an amazing Draconids display on par with the 2011 event. On average, the meteor shower creates between 10 or so meteors an hour, he added.
If you plan to seek out the Draconid meteor shower tonight, here are some handy tips:
Find a dark place: It seems like a no-brainer, but clear, dark skies away from the interference of city lights offer the best chances for meteor-seeking night sky observers.
Get comfortable: Sitting upright with your head craned upward can get uncomfortable after awhile. A reclining lawn chair may be a better bet.
Dress warmly: The Fall season is in full swing for Northern Hemisphere observers so a few extra layers to ward off the evening chill is a good idea.
Time it right: According to New York meteorologist Joe Rao, SPACE.com's night sky columnist, the Draconid meteor shower are a bit unusual when it comes to the best observing time. For most meteor showers, the optimum time for observation is around the midnight hour, but the Draconids tend to be at their best in the evening time just after dusk, Rao has explained in the past.
"Their radiant (apparent point of origin due to perspective) is highest after dusk; it moves lower throughout the night and is near the horizon at dawn," Rao wrote ahead of last year's Draconid display.
The Draconid meteor shower is one of two big night sky meteor sights in October. There are several minor meteor showers throughout the month, but the Draconids and the annual Orionid meteor shower later in October are the main players to look out for.
The Orionid meteor shower one of two showers created by the leftovers of the famed Halley's Comet (the Eta Aquarid meteor display in May is the other). It will peak on Oct. 22, according to the International Meteor Organization. [ Amazing Orionid Meteor Shower Photos ]
