The Eta Aquarids meteor shower, originating from Halley’s Comet, is set to peak on Monday night into early Tuesday, with up to 50 meteors visible per hour. Best viewed before dawn, these fast meteors, traveling nearly 41 miles per second, are visible from both hemispheres, though conditions may be affected by rain in parts of the U.S. The shower is active until May 28, and viewers are advised to find dark locations for optimal viewing.
