New York to London Milky Way, by Alessandro Merga, recently featured as NASA's Astronomy photo of the day.
Of course the sky was clear and dark at that altitude, ideal conditions for astronomical imaging.
But there were challenges to overcome while looking out a passenger window of the aircraft moving at nearly 1,000 kilometers per hour (600 mph).
Over 90 exposures of 30 seconds or less were attempted with a fast lens and sensitive camera setting, using a small, flexible tripod and a blanket to block reflections of interior lighting.
In the end, one 10 second long exposure resulted in this steady and colorful example of airborne astronomy.
