Each Dot is a Galaxy Containing Billions of Stars

In 1986, astronomer Felix J. Lockman discovered a curious region in space where there is little neutral hydrogen gas. This region, called the Lockman Hole, provides a keyhole through which astronomers can observe distant galaxies.

Using the Herschel Space Observatory, scientists at the European Space Agency decided to take a peek through the Lockman Hole and found thousands of galaxies. Each dot you see is an entire galaxy containing billions of stars:

The galaxies seen in this image are all in the distant Universe and appear as they did 10–12 billion years ago. They are colour coded in blue, green, and red to represent the three wavebands used for Herschel’s observation. Those appearing in white have equal intensity in all three bands and are the ones forming the most stars. The galaxies shown in red are likely to be the most distant, appearing as they did around 12 billion years ago.

Just think about it.

it's hard to comprehend the number of stars in our own galaxy, never mind the gazillion stars in that picture.

and then there's the distance involved...

Very cool.
I stared at it a while and saw Rana, the Frog god who used to stop styluses from falling off mimeograph machines when printing up fanzines.

Sometimes I swear if we zoom out far enough, we're going to see someones carpet, or living room rug... or a dustbunny under a cosmic bed...etc.
