A new map of the universe displays for the first time the entirety of the known universe with stunning precision and beauty.
Created by astronomers at Johns Hopkins University using data mined over two decades by the Sloan Digital Sky Survey, the map allows the public to experience data previously only available to scientists.
“I’ve been very inspired by images of astronomy, stars, nebulae and galaxies, and now it’s time to create a new type of image to inspire people,” says map designer Brice Ménard, Professor at Johns Hopkins.
Astrophysicists around the world have been analyzing this data for years, resulting in thousands of them Scientific papers and discoveries. But no one has taken the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everyone what the universe really looks like.”
The Sloan Digital Sky Survey is a groundbreaking effort to capture images night sky Through a telescope based in New Mexico. Night after night for years, the telescope has aimed at slightly different locations to capture this extraordinarily wide perspective.
The map, compiled by Maynard with the help of Nikita Shtarkman, a former computer science student at Johns Hopkins University, depicts a slice of the universe, or about 200,000 galaxies — every point on the map is a galaxy and each galaxy contains billions of stars and planets. The Milky Way is simply one of these points, the one at the bottom of the map.
The expansion of the universe is making this map even more colorful. The longer the object, the redder it is. The top of the map reveals the first flash of radiation that was emitted shortly after the Big Bang, 13.7 billion years ago.
“In this map, we’re just a speck at the bottom, just one pixel. And when I say, I mean our galaxy, the Milky Way which has billions of stars “We’re used to seeing astronomical images that show a single galaxy here, a single galaxy there, or maybe a group of galaxies,” says Maynard. “But what this map shows is on a very different scale.”
Maynard hopes people will experience the map’s undeniable beauty and incredible scale.
“From this bottom spot,” he says, “we’re able to map galaxies across the entire universe, and that says something about the power of science.”
