“From this speck at the bottom,” he says, “we are able to map out galaxies across the entire universe, and that says something about the power of science.”Īctually this is essential in effort to get off earth. Ménard hopes people will experience both the map’s undeniable beauty and its awe-inspiring sweep of scale. But what this map shows is a very, very different scale.” “We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets,” Ménard says. “In this map, we are just a speck at the very bottom, just one pixel. The first flash of radiation emitted soon after the Big Bang, 13.7 billion years ago is revealed at the top of the map. Because of this, the farther an object is, the redder it appears. The map is even more colorful due to the expansion of the universe. Ménard assembled the map with the help of former Johns Hopkins computer science student Nikita Shtarkman.Ĭreated by Johns Hopkins University astronomers with data mined over two decades by the Sloan Digital Sky Survey, the map allows the public to experience data previously only accessible to scientists. The Milky Way is simply one of these dots, the one at the very bottom of the map. The map visualizes a slice of the universe, or about 200,000 galaxies-each dot on the map is a galaxy and each galaxy contains billions of stars and planets. Night after night for years, the telescope aimed at slightly different locations to capture this unusually broad perspective. The Sloan Digital Sky Survey is a pioneering effort to capture the night sky through a telescope based in New Mexico. Our goal here is to show everybody what the universe really looks like.” But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. “Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. “Growing up I was very inspired by astronomy pictures, stars, nebulae, and galaxies, and now it’s our time to create a new type of picture to inspire people,” says map creator Brice Ménard, a professor at Johns Hopkins. It is available online, where it can also be downloaded for free.Ī new map of the universe displays for the first time the span of the entire known cosmos with pinpoint accuracy and sweeping beauty. The interactive map depicts the actual position and real colors of 200,000 galaxies.
