Firefly Trails and the Summer Milky Way
Image Credit & Copyright: Malcolm Park (North York Astronomical Association)
Explanation: A camera fixed low to a tripod on a
northern summer's eve captured the series of images used in this serene, southern Ontario skyscape. The lakeside view frames our fair galaxy above calm water and the night's quintessential luminous apparitions. But the trails of light are neither
satellite glint, nor
meteor flash, nor
auroral glow. In the wide-field composite constructed with four consecutive 15 second exposures, a pulsing
firefly enters at the right, first wandering toward the camera, then left and back toward the lake, the central Milky Way rising in the background.
