Interactive Sky Viewer*
Welcome to your personalized tour of the sky! Sky and Telescope's Mobile Sky Chart allows you to create a star map of any location, worldwide, at any time of night, every day of the year.
This interactive application displays the sky in two ways: the Horizon View simulates a naked-eye panoramic scene of a given piece of sky, the All-Sky Chart displays the entire sky currently visible in your location.
Connecting lines help identify constellations. The 26 brightest stars in the sky are named to offer additional orientation. Become a sky expert and enjoy this informative guide as you explore the view from your own backyard.
