The map charts a broad expanse of the universe, from the Milky Way to ‘the edge of what can be seen.’
A new map of the universe displays the span of the entire known cosmos for the first time with pinpoint accuracy and sweeping beauty. Compiled from data mined over two decades by the Sloan Digital Sky Survey, the map was created by astronomers from Johns Hopkins University. It allows the public to experience data previously only accessible to scientists.
The interactive map depicts the actual position and real colors of 200,000 galaxies. It is available online, where it can also be downloaded for free.
The Sloan Digital Sky Survey is a pioneering effort to capture the night sky through a telescope based in New Mexico. Night after night for years, the telescope aimed at slightly different locations to capture this unusually broad perspective.
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. The Milky Way is simply one of these dots, the one at the very bottom of the map. Ménard assembled the map with the help of former Johns Hopkins computer science student Nikita Shtarkman.
The map is even more colorful due to the expansion of the universe. Because of this, the farther an object is, the redder it appears. The first flash of radiation emitted soon after the Big Bang
The Big Bang is the leading cosmological model explaining how the universe as we know it began approximately 13.8 billion years ago. The first flash of radiation emitted soon after the Big Bang, 13.7 billion years ago is revealed at the top of the map.
“In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets,” Ménard says. “We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale.”
Ménard hopes people will experience both the map’s undeniable beauty and its awe-inspiring sweep of scale.
“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.”
