The Dark Energy Spectroscopic Instrument (DESI) is mapping millions of celestial objects to better understand dark energy—the ...

Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment has produced confounding results.

Galaxies are the building blocks of the universe. Clusters of galaxies, and clusters of clusters of galaxies, called superclusters ... millions of galaxies and map their distribution in space.

These methods could have applications beyond dark matter research, potentially informing studies of dark energy, black holes, and the early universe. The use of 3D galaxy maps and field-level ...

The telescope will capture a three-dimensional map of the universe, collecting data on more than 450 million galaxies and over 100 million stars ...
