The Lyrids are the trail of particles left in the path of the Comet C/1861 G1 Thatcher, which our planet runs into every April. Amazingly, there are reports of the shower being observed as far back as 2,600 years. Conditions aren't always optimal to see it, as light from the moon can easily interfere with a good view, but this year the shower's peak falls just a few days before the new moon, which means if you can escape enough environmental light pollution, stargazers should be able to catch quite a show.
While the shower can produce as many as 100 meteors an hour, this year's will likely boast an average of 10 to 20, which amounts to one meteor every three or so minutes. According to the American Meteor Society, the Lyrids generally lack a "persistent" trail but can produce dramatic fireballs as they enter the Earth's atmosphere.
