April 2026 Skywatch: Mercury's Best View, Green Comet Glow, and Lyrid Meteors
April 2026 offers a rare string of skywatching events: Mercury reaches its greatest elongation on April 3 for one of the year’s clearest views; Comet C/2025 R3 brightens in mid-April with a green glow and peaks around April 17, followed by its closest approach to Earth on April 27; the Lyrid meteor shower peaks April 21–22 with about 15–20 meteors per hour, providing multiple rewarding nights of stargazing in the Northern Hemisphere.
