Tool now mounted on the Mayall telescope in Arizona
The device is DESI (Dark Energy Spectroscopic Instrument) for the search for dark energy in the Universe has captured the first photograph. First the DESI the image of the spiral galaxy M 51, the Whirlpool, located in the constellation Canes venatici, which lies about 23 million light years from Earth.

First the machine DESI
Now the tool is mounted on the Mayall telescope in Arizona (USA). The first pictures were taken in a “space hunter” during early tests, which were tested recently installed six large lenses.
As expected, when the training is DESI is completed, it will be able to study the spectra of more than 30 million galaxies and quasars that can inform about the distance and speed of these objects. The latter, in turn, will help to learn more about dark energy — a hypothetical energy, which helps to explain the accelerated expansion of the Universe.
