The stunning new map of the Milky Way shows 800 million stars, galaxies and nearby Earth's asteroids



At first it resembles a planet: dark, snowy and dissected down in the middle with a dark red scar. But come a little closer and realize that you are looking for something much larger than a planet – more than 100 billion planets.

This is a new map of space, made up of four-year observations from the Pan-Stars Observatory in Maui, Hawaii. Hidden in this mosaic picture of the Milky Way (this is the large red spot in the middle) and its close cosmic neighborhood are more than 800 million stars, galaxies and wandering interstellar objects that are seen from the point of view of the Mountain Observatory.

Soon, stars around the world will have the opportunity to study each of these objects (and millions more) in detail thanks to what scientists from Hawaii University in Mano (UH) have called the greatest release of astronomical data from all the time .

In partnership with the Baltimore Space Telescope Science Institute, UH released 1.6 billion five-byte data (1.6 million gigabytes) recorded by the Pan-STARRS telescope since 2010. This massive ejection of data is equivalent to about 2 billion sega, or 30,000 times the total text content of Wikipedia, according to a UH statement.

"We put the universe in a box and everyone can look," said Conrad Holmberg, a project engineer for the project.

Of course, the entire universe is not here – just the huge vault in the sky, seen over Hawaii, centered on the Northern Star, Polaris. A piece of the Milky Way galaxy cuts the middle of the image, becoming brighter near the bottom of the frame, where the galaxy fills the black hole in the center of the night. Thick clouds of interstellar dust that swallow blue light and seem to glow in red, puddles along the galaxy.

The Pan-STARRS telescope recorded much smaller shots that made this image possible with a 1.4 billion-pixel digital camera that broke the sky in visible and near-infrared light. Astronomers scanned the sky 12 times, using five different telescopic filters for four years. The combined results of these scans are visible in this image as well as the new data message.

According to Ken Chambers, Director of Pan-STARRS Observatories, the observations of this telescope have already helped the astronomical community to study the value of the cosmic galaxy phenomenon over the last few years (partly thanks to a smaller data set released in 2016) .

"During the search for objects close to Earth, Pan-STARRS made a lot of discoveries from" Oumuamua, passing through our solar system to lonely planets among the stars, "says the Chambers statement. "We hope people will discover all the things we have missed in this incredibly large and rich set of data."
