Knowing Your Place in Nature

07 Jan

To fully respect nature it helps to know where your place is in it.

Take a gander at an animation of 400,000 galaxies in their actual positions and you’ll have a new appreciation for how small we are and how wonderful our small oasis in space is. This animation was derived from the latest Sloan Digital Sky Survey (SDSS-III) that identified 535,995 newly observed galaxies, 102,100 quasars, and 116,474 stars. This is well worth watching full-screen with the volume loud.

There are close to 400,000 galaxies in the animation, each containing between 100 billion and 400 billion stars. The images of the actual galaxies in these positions derived from the Sloan Digital Sky Survey (SDSS) Data Release 7. As vast as this slice of space seems, it only corresponds to a small fraction of the known universe.
