Lyrids Meteor Shower to Illuminate April Skies

The Lyrids meteor shower will be visible in the night sky between April 16 and April 23, with peak activity expected in the early morning hours after midnight.

Annual Celestial Event

The Lyrids meteor shower occurs annually in April when Earth passes through debris left by Comet Thatcher. This comet last passed through the inner Solar System hundreds of years ago. The meteors are fragments from Comet Thatcher that enter Earth's atmosphere.

The meteors are composed of rock and dust, some as small as a grain of sand. They enter the atmosphere at speeds up to 40 kilometers per second and burn up, creating the visible streaks of light we observe.

How and When to Watch

The best viewing time is after midnight, particularly in the early morning hours. Observers should look toward the northeastern sky, but meteors can appear anywhere overhead.

It takes approximately 20 minutes for human eyes to adjust to darkness for optimal viewing.

Light pollution from cities and towns can significantly reduce the visibility of fainter meteors, so finding a dark location is recommended.

Additional Facts

• On average, the Lyrids produce 15 to 20 meteors per hour at their peak.
• Earth receives approximately 100 tons of material from space daily, most of which burns up in the atmosphere.
• Occasionally, larger fragments survive atmospheric entry and reach the ground as meteorites.

Meteorites can be identified by several characteristics, including greater density than typical rocks, a dark fusion crust from their fiery descent, magnetic properties due to iron content, and metallic flecks visible when broken.

For scale, a typical cumulus cloud has a mass equivalent to hundreds of thousands of kilograms of water.
