The map charts a large 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.

“Rising up I used to be very impressed by means of astronomy photos, stars, nebulae, and galaxies, and now it’s our time to create a brand new form of image to encourage other folks,” says map writer Brice Ménard, a professor at Johns Hopkins. “Astrophysicists all over the world had been inspecting this information for years, resulting in hundreds of clinical papers and discoveries. However no person took the time to create a map this is gorgeous, scientifically correct, and out there to those that don’t seem to be scientists. Our purpose here’s to turn everyone what the universe truly seems like.”

The Sloan Virtual Sky Survey is a pioneering effort to seize the night time sky thru a telescope primarily based in New Mexico. Night time after night time for years, the telescope geared toward moderately other places to seize this strangely large standpoint.

The map visualizes a slice of the universe, or about 200,000 galaxies—every dot at the map is a galaxy and every galaxy incorporates billions of stars and planets. The Milky Manner is just any such dots, the only on the very backside of the map. Ménard assembled the map with the assistance of former Johns Hopkins pc science scholar Nikita Shtarkman.

The map is much more colourful because of the growth of the universe. As a result of this, the farther an object is, the redder it seems that. The primary flash of radiation emitted quickly 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.”
