A deep look at the bright matter in our universe, as seen by the Sloan Digital Sky Survey. This survey was performed by a 2.5m telescope, located in New Mexico, from 2000 to 2008, covering a solid slice of the the northern-hemisphere sky plus three delicate tranches of the southern. Our viewpoint is at the center, where the northern- and southern-hemisphere data come together.
The features revealed at this scale – filaments, sheets and supergalaxy clusters – are too big to be visible in the night sky of Earth. They are composed mainly of the brightest objects: supernovae, galaxies and quasars.
This model is etched in a heavy glass block 2¼ x 3 x 4¾" tall. At the scale of this map, the Milky Way would be less than 1mm wide.
Credit goes to Dr. Aragon Calvo and the Sloan Digital Sky Survey (SDSS) Collaboration. This data is used by their permission and with my thanks.

Without illumination the crystal works best on a dark background. It comes with clear rubber feet to avoid scratching your desk or mantel. On the left, this illuminated base is a great way to light up your universe! It has a black glossy finish with white LEDs that are cool and energy-efficient. Bright enough for the office by day, or a brilliant nightlight. |
