Best viewed from the Northern Hemisphere, the Lyrid meteor shower is the world's oldest known of its kind and reliably occurs every April.

Active since last week, the shower is formed from a comet’s debris and is forecast to produce the most fireballs overnight.

Be on the lookout for shooting stars and fireballs when two meteor showers — the Lyrids meteor shower and Eta Aquarids shower — will overlap through April 26. Why it matters: It's the latest astronomical event in an active few weeks of skywatching between last month's Blood Moon total lunar eclipse and April's Pink Moon.
