The celestial globe on display is a map of the sky or star map, shaped as a globe. However, it is not just a map of the sky at night, because it also shows the position of the sun during the day. Click on the virtual globe to see the Earth as viewed from space, showing the angle of sunlight.
Please wait, applet loading.
Click on any point in the image above, and the globe will
be redrawn with the selected point at the center of the view.
Areas of sunlight and darkness are updated every five minutes
to keep up with the rotation of the Earth.
