Star Map draws the real night sky above your location at the current moment, and at
any other date you choose. It is free, needs no sign-up, and runs entirely in your
browser.
What you can see
All 88 constellations, drawn as joined figures over the real stars that form them.
The Sun, the Moon with its correct phase, and every planet from Mercury to Neptune.
110 Messier objects and around 740 NGC and IC deep sky objects — galaxies, nebulae
and star clusters — drawn at their true size in the sky.
Satellites overhead, including the International Space Station and the Chinese
space station Tiangong, with the time and direction of their next visible pass.
Nearly 9,000 stars down to magnitude 6.5, the limit of the naked eye.
What you can do
Look around by dragging, and zoom with a pinch or scroll.
Set your location by GPS, by choosing a city, or by typing coordinates.
Travel to any date and time, past or future, or run the clock forward to watch the
sky turn.
Search for any star, planet, constellation, satellite or deep sky object and jump
straight to it.
Read telescope coordinates for anything you find: right ascension and declination
in J2000 and of date, altitude and azimuth, and rise, set and transit times.
See through the ground to find objects currently below your horizon.
