This 3D map of the universe shows 14.7 million galaxies in their true positions as seen from Earth. To study dark energy’s effects over the past 11 billion years, DESI has created the largest 3D map of our cosmos ever constructed, with the most precise measurements to date. This is the first time scientists have measured the expansion history of the young universe with a precision better than 1%, giving us our best view yet of how the universe evolved. #space #galaxy #astronomy | Nikola Sagan
