- By analyzing the light from 10 million galaxies, astronomers have built the largest dark matter map ever created.
- The map visualizes an intricate cosmic web of dark matter and galaxies one billion light-years across.
- Understanding the structure of dark matter will help us understand the evolution of the Universe.
Astronomers have created a vast cosmic map revealing an intricate web of dark matter and galaxies spanning a distance of one billion light-years.
This unprecedented task was achieved not by observing dark matter directly, but by observing its gravitational effects on ancient light traveling from galaxies that existed when the Universe was half the age it is now.
Constructed by astronomers from the University of British Columbia and the University of Edinburgh, this is the largest dark matter map ever built and took five years to complete.
The research was presented at the American Astronomical Society meeting in Austin, Texas, on Monday.
