Eta Aquarid Meteor Shower

The annual Eta Aquarid meteor shower is expected to peak early Tuesday morning with meteors flying into Earth's atmosphere at speeds of 40.7 miles per second, originating from Halley's Comet debris. Northern Hemisphere may see 10 to 20 meteors per hour, while those in the Southern Hemisphere may see a more active sky. The moon will set by 3 a.m. on May 6, providing ideal dark skies for meteor spotting.

Summer Solstice in the Northern Hemisphere

The summer solstice in the Northern Hemisphere arrived early this year, marking the longest day of the year. The phenomenon occurs when Earth's north pole is most tilted towards the sun. The early arrival is due to quirks in the calendar and leap years.
