Kemble's Cascade, a chain of stars in Camelopardalis, leads to the 6th magnitude cluster NGC 1502 and survives bright moonlight. The constellation sits in the north, east of the Little Dipper and between Cassiopeia and Ursa Major, and the cascade holds about two dozen stars of 7th to 10th magnitude over 2.5 degrees. Binoculars or a finder scope take in the whole line at once.

Blue noctilucent clouds spread across the sky above a field near Linkoping, Sweden, in early August 2026 in this Astronomy Picture of the Day. They are the highest clouds, technically polar mesospheric clouds, and become visible after sunset in summer when sunlight from below the horizon lights them. Much about them has only been discovered in the past two decades, so look for them after summer sunsets.
