A completely pan-and-zoomable picture of the Milky Way galaxy

Go Bigger...
Bigger Still....
Even bigger....
Behold! This is the star-forming region G305, an enormous cloud of gas about 12,000 light years away which is busily birthing stars. About 10,000 stars can be seen in this photo.





And here's another zoom-able picture by  Stéphane Guisard at the ESO's Paranal Observatory in Chile

The center of the Milky Way galaxy

The above image shows an area of the sky that is about twice of what you can cover up with your outstretched hand.  It is a mosaic shot over the course of 29 nights for a total of 200 hours of exposure over 1200 separate photos.

zoom in on the Milky Way photo

There are tens of millions of stars in this picture at least.  And this is less than one-thousandth of all the stars you can see in the night sky!
