Star gazing navigation

Stargazing apps on your phone are magic. They work like AR-augmented reality — overlaying the night sky with outlines of constellations, star and planet names, paths of the moon, and even satellite, comet and asteroid sightings. The apps are uncannily accurate, and easy to understand. There are free apps and expensive subscriptions, but I use Star Walk 2 which cost $3. It’s the best $3 space investment I’ve ever made. — KK
