The Lyrid meteor shower is already showing in the night sky, and its best display is coming between the night of April 21 and the early morning of April 22. Under dark skies, NASA says observers may see 15 to 20 meteors an hour as Earth passes through the debris left by comet C/1861 G1, also known as Thatcher.
The shower began to appear as early as April 14, but the peak is the stretch that matters most. The Lyrids are named for the constellation Lyra, from which the meteors seem to radiate, and Vega, the fifth brightest star in the sky, can help viewers orient themselves while looking up.
For anyone hoping to catch the best of the display, timing and darkness matter. The shower is usually visible from 10 pm to dawn, but early morning offers the strongest viewing conditions, and the human eye can take 20 to 30 minutes to fully adjust after lights are gone. The moon will be in an early crescent phase during the peak, so moonlight should interfere very little.
That makes this year’s view more favorable than many casual stargazers may expect. Observers are advised to get away from light pollution and, if possible, watch from high ground, where the sky is darker and the meteors stand out more clearly against the background.
The setting behind the shower reaches back centuries. Comet C/1861 G1, discovered in 1861, takes about 415 years to complete one trip around the sun, and Earth meets the cloud of fragments it left behind each April. The result is one of the sky’s oldest recurring spring events, and this week it is at its most visible.
For viewers in the northern hemisphere, the answer is straightforward: the best chance to see the Lyrids comes in the dark hours before dawn on April 22, when the sky is still black, the moon is a thin crescent and the shower is at its peak.
