Greg Diesel-Walck captured the beautiful morning twilight on the day of the summer solstice, June 21. He was at Dyke Marsh Wildlife Preserve in Alexandria, Virginia. Thank you, Greg.
The latest twilights of year are happening now for 40 degrees north latitude. Morning twilight on the northern half of Earth is at its most beautiful now, too. Enjoy these photos from EarthSky friends. Thanks to all who contributed.
Night launch! Liftoff is targeted at 11:30 p.m. EDT on June 24 (03:30 UTC on June 25; translate UTC to your time). There's a 4-hour launch window. SpaceX is calling the launch its most difficult ever, because the rocket must release 24 satellites into 3 different orbits. More info and how to watch.
