The DESI Spectroscopy instrument, installed in the Arizona desert, will direct 5,000 fiber-optic eyes into the night sky over five years to capture and analyze the light emitted from 35 million eyes. Galaxy At different times in the universe.
The data should enable scientists to understand a mysterious force called “black energy” that is responsible for accelerating the expansion of the universe, explained the Berkeley Lab, which oversees the program.
Due to the expansion of the universe, the galaxies are moving further away from each other, and the further away they are, the more light they emit toward the larger wavelengths of the observed spectrum, that is, towards the red, explained the French Atomic Committee. Energy. (CEA), which is involved in astronomical missions.

By analyzing a galaxy’s energetic radiation, DESI will be able to measure the redshift associated with distance velocity, and thus obtain information about its distance from Earth.
The French General Authority added that researchers will also be able to create a three-dimensional map of the universe “in unprecedented detail, by multiplying the number of spectra of a given galaxy by ten.”
DESI can collect “5,000 spectra of galaxies in 20 minutes,” according to Christov Yiichi, a CEA cosmologist.

With a map of the universe, researchers hope to better understand the nature and effects of black energy. This invisible component of the universe acts as a repulsive force which explains why the expansion of the universe has been accelerating for thousands of years.
