Every April, Earth drifts through a trail of dust left behind by Comet Thatcher—a long-period comet that last passed by in 1861 and won’t return until 2276.

But here’s the twist: we’re not seeing the comet itself.
We’re seeing the dust it shed thousands of years ago.

Each year, as Earth orbits the Sun, it plows through this lingering trail of debris. Tiny bits of comet dust—some no bigger than grains of sand—slam into our atmosphere and burn up, creating the Lyrids meteor shower.

It’s a cosmic echo: the comet is long gone, but its trail still lights up the sky.

Where to Look:

• In the Northern Hemisphere, face east or northeast after midnight. The later it gets, the better the show.

• In the Southern Hemisphere, your best bet is to look low toward the north/northeast before dawn.

• The meteors appear to radiate from the constellation Lyra, but they’ll streak across all parts of the sky.

• Avoid city lights, give your eyes 20 minutes to adjust, and settle in under a dark, clear sky.

This year’s peak is expected around April 21–22, just before dawn. Bundle up, look up, and enjoy the dust trails of a comet that no one alive has ever seen.
