This week, skywatchers in the Northern Hemisphere will get a view of the Lyrid meteor shower, the dusty trail of a comet with a centuries-long orbit around the sun. The Lyrid meteors streak across the sky between April 16 and April 25, so skywatchers have a chance to see them during that window, weather permitting.

The best day to see Lyrid meteors will be extremely early in the morning on Saturday, April 22, NASA meteor expert Bill Cooke told Space.com. As with most meteor showers, the peak viewing time will be before dawn.

Cooke said the average Lyrid shower produces 15 to 20 meteors per hour. Some years, the Lyrid meteor shower intensifies and can produce up to 100 meteors per hour in what's called an "outburst," but it is difficult to predict exactly when that will happen.

"People say there is some periodicity there," Cooke said, "but the data doesn't support that." Although there is an average of 30 years between these outbursts, that's only an average; the actual number of years between the events varies, Cooke said. [Amazing Lyrid Meteor Shower Photos]

The annual Lyrid meteor shower runs from April 16 to 25 and peaks before dawn on Saturday, April 22. The moon should not spoil the show, which can produce up to 18 meteors per hour. Watch for occasional fireballs.

The radiant — the point from which the meteors appear to originate — will be high in the evening sky in the constellation Lyra to the northeast of Vega, one of the brightest stars visible in the night sky this time of year. Don't look directly toward the radiant, though, because you might miss the meteors with the longest tails.

The new moon will be a few days later, on April 26, so moonlight won't obstruct the view of the meteors as they streak across the night sky. Away from city lights, the sky will be about as dark as it can get.

The Lyrid meteor shower is of medium brightness, but not as luminous as the famous Perseid meteor shower in August, which tends to produce more prominent trails, Cooke said.

Lyrid meteors are little pieces of Comet Thatcher, a long-period comet that orbits the sun about once every 415 years. Pieces of debris left in the comet's wake, however, make an appearance every year. (Comet Thatcher's most recent perihelion, or closest approach to the sun, was in 1861. It won't be back until the year 2276.) 

Meteor showers occur when the Earth crosses the path of a comet, colliding with a trail of comet crumbs. That's why they happen around the same time every year and appear to originate from specific points in the sky. As they burn up in the atmosphere, the meteors leave bright streaks in the sky commonly referred to as "shooting stars." [Infographic: How Meteor Showers Work]

Lyrid meteors come in fast — though not as fast as the Leonids, which peak in November, Cooke said. "The Leonids hit us head-on," he said. "The Lyrids are more like hitting the left front fender."

The Lyrids are one of the oldest recorded showers, Cooke said, with observations going back to 687 B.C. You don't need any kind of special equipment to see the meteors; just look up at the dark sky, be patient and enjoy the show.
