Durham scientists help create telescope which can see into the past

Researchers have used Durham academics and developed a telescope that can ‘look back in time’ as well as help them learn how our universe is really expanding.

The instrument, known as DESI (Dark Energy Spectroscopic Instrument), was designed as well as built by one international partnership, which includes Durham University.

The 5000 fibre-optic lens of the instrument was aimed at the sky for the very first time on Monday night.

DESI is designed for offering very accurate measurements of the expansion rate of the universe. Such expansion rate, although thought believed to have decelerated in early Universe because of gravity, recently was discovered to be surging. However, the experts still don’t know why such a change is really happening.

It’s believed that dark energy is triggering this, and the instrument will try to measure the effects of it.

DESI shot its first pictures of the galaxies that are at a distance of 11bn light years from Earth when it was installed on the Mayall Telescope on Monday at Arizona’s Kitt Peak National Observatory.

When the official observations start from the year 2020, the telescope will be utilized to ‘see into the past’ to develop the most precise 3-dimensional map of our universe, examining the light sent around 11bn years ago that just reached Earth recently.
