"From this speck at the bottom," he says, "we are able to map out galaxies across the entire universe, and that that says something about the power of science. 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." The main objective of DESI is to reveal more about the dark energy that is thought to make up 70 percent of the Universe as well as speeding up its expansion. Cosmologists have produced the biggest map yet of the Universe’s structure, and found that. The Sloan Digital Sky Survey has created the most detailed three-dimensional maps of the Universe ever made, with deep multi-color images of one-third of the sky, and spectra for more than three million astronomical objects. Above: A slice through the 3D map of galaxies from the completed Sloan Digital Sky Survey (left) and the first few months of the Dark Energy Spectroscopic Instrument (right). "We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. Published: 10 August 2017 Cosmic map reveals a not-so-lumpy Universe. 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. A global consortium of astrophysicists have created the world’s largest three-dimensional map of the universe, a project 20 years in the making that researchers say helps better explain the. The top of the map reveals the first flash of radiation emitted soon after the Big Bang, 13.7 billion years ago. The farther an object, the redder it appears. The expansion of the universe contributes to make this map even more colorful. The Milky Way is simply one of these dots, the one at the very bottom of the map. The map, which Ménard assembled with the help of former Johns Hopkins computer science student Nikita Shtarkman, 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. From this map, researchers measure patterns in the distribution of galaxies, which give several key parameters of our Universe to better than one percent accuracy. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. A close look at the map reveals the filaments and voids that define the structure in the Universe, starting from the time when the Universe was only about 300,000 years old.
