The Dark Energy Spectroscopic Telescope Ready for the Dark Matter

Despite the pandemic, the astrophysicists do not abandon the idea of finding the dark matter. The Lawrence Berkeley National Laboratory reported that the Dark Energy spectroscopic telescope, or as it is also knows as DESI, is ready for use. It is located in southwestern Arizona and is run by the NSF National Laboratory for Optical and Infrared Astronomy Research. That is the most powerful reflex telescope with a 4-meter main mirror mounted on an equatorial support.

It has an ability to display millions of galaxies in 3D. Recently, the DESI project has advanced significantly in technical equipment in order to achieve its goal by the time of launch. It will collect the light of millions of galaxies and ultra bright quasar objects.

To do that, the scientists have proposed the usage of automatically installed fiber optic cables using a group of rotating robots. The collected radiation of galaxies will be measured by ten devices that separate flares into spectra and individual lights.

The analysis of these data will allow the scientists to make a map of the Universe in 3D format. In that way, the astrophysicists hope to learn as much as possible about the mysterious dark matter, that is the driving force behind the accelerating expansion of the Universe.

The research results will give new knowledge about the life cycles and evolution of galaxies and the space network, united by dark matter. DESI is a project developed with the participation of an international community of the scientists. It includes about 500 researchers from 13 countries.

A Project Director Michael Levy noted that ten years of complex work f in the culmination of the start of equipment operation. Astrophysicists understand the exclusive privilege of working with a unique telescope and the data that it will transmit to earth laboratories. With its help, they learn what is beyond the boundaries of outer space known to science.
