Announced the largest 3D universe map ever

A group of American astronomers, led by astronomer Nikhil Padmanabhan and David Schlegel, have published the largest 3D universe map ever.

Built in 10 V-shaped cosmic sections from the north of the sky, this new map includes a vast space of space containing more than 1 million galaxies, including 600,000 red light galaxies. and stretches to 5.6 billion light-years, equivalent to 40% of the time if it goes back to the Big Bang.

" The new thing on this map is that it is the largest map ever, " astronomer Nikhil Padmanabhan from Princeton University said.

David Schlegel, from Lawrence Berkeley National Laboratory, said that because it is the largest map so far, " it allows us to measure the structure of cosmic objects in about 1 billion light years. light from side to side ".

This new map experiences a universe filled with dark energy sources and these energy sources are pushing galaxies farther apart at a faster and faster pace making the universe expand at a rapid rate. than. This dark energy accounts for 75% of the energy of the universe and is still the biggest mystery that science has yet to explain.

To complete the new map of this universe, American astronomers had to determine the distance between galaxies through spectroscopic techniques.
