3D map reveals details of 7.5 million galaxies

American scientists have completed drawing details of 7.5 million galaxies out of the 35 million that will be included in a three-dimensional map of the universe, in a project expected to take five years..
Mail Online stated that the map is the most detailed and clearest of the universe and works by the dark energy spectroscopy tool, and completed the observation and drawing of galaxies within seven months..

A group of scientists from different countries are cooperating, led by the Lawrence Berkeley National Laboratory of the US Department of Energy in California, and the research team includes scientists from Britain, China, Spain, France, the United States and other countries..

The aim of the scientific project is to draw a “tremendously detailed three-dimensional map to explain the dark energy that makes up 68% of the universe and is accelerating its expansion.”

The map adds about one million galaxies per month, in order to achieve a drawing of 35 million unique galaxies in the universe, each studied within 20 minutes..

Having the map will allow astronomers to understand how the universe began and where it is headed next, including whether it will expand forever, collapse, or separate..

Scientists use more than 5,000 telescopes, each operating separately, along with fiber-optic technology to split the light from each galaxy into separate colors..

Each telescope can scan a single galaxy for up to 20 minutes, separating the light into colored bands.

The colors bear clues to the chemical composition, distance and speed of individual galaxies.

Scientists hope to achieve scientific results about the formation and evolution of galaxies, including the exploration of rare objects from very mineral-poor galaxies and dwarf galaxies..
