Biggest Map of Universe Helps Confirm Dark Energy
Written by The Night Sky Guy on August 9, 2012 – 11:15 pm -
Similar to how medieval maps of Earth ranged from speculations of the unknown to concrete scientific observations, cosmologists today are slowly refining our understanding of the structure and evolution of the Universe as a whole. Now a team of astronomers has announced that they have created a 12 billion light year-deep survey map that reveals the most precise makeup of the Universe to date. Known as the Sloan Digital Sky Survey III, the epic new map targets nearly a million galaxies, which not only provides the most comprehensive view of the night sky ever made but sheds light on mysterious dark energy and history of the expansion of the universe.
Check out this amazing animation fly through of the galaxies plotted in the SDSS survey just released. Amazing to think that you can see nearly 400,000 galaxies in the animation.
