The Big Picture
The largest astronomical image in the world is glazed onto a porcelain enamel wall 152 feet long and 20 feet tall. Centered on the Virgo Cluster of galaxies (of which our Milky Way is a part), it reveals the amount of sky that your index finger would cover if held a foot from your eye at a resolution as if your eyes were 36-inch telescopes. Caltech estimates that the image includes over a million galaxies, ranging in distance from millions to billions of light years. You can also see hundreds of thousands of stars in the Milky Way and two asteroids and a comet here in our own solar system.
