SCRIPT Euclid: Exploring the dark matter 26/02/2015 Internet text: At ESA's ESTEC center near Amsterdam and at CERN in Geneva, scientists are trying to explore 'The Dark Side': the mysterious forces of dark matter and dark energy which are thought to rule the cosmos. The Euclid space telescope will soon offer a unique point of view on the cosmos; while on the ground, at sub-atomic level, CERN’s particle accelerator will produce new observations. 00 00 00 ESA Generic and Title 00 00 10 TEXT
At the beginning of the past century, Albert Einstein was the first to hypothesize that the ‘empty space’ in the universe - is not actually empty. A hundred years later, the nature of that empty space is still unknown. But thanks to the results of the Planck space observatory mission, scientists have at least concurred on the existence of dark matter.

They calculate that ordinary visible matter accounts for about 5 percent of our universe. The rest is dark matter and a repulsive force called dark energy, which is accelerating the universe’s expansion. Although we don't know much about dark matter or dark energy; this could change quite soon.

TEXT
ESA is now building a new space telescope called Euclid; which will look specifically at the ‘hidden side’ of the universe. (Images from Euronews ESTECT in Amsterdam from “Dark Matter dark energy, ESA and CERN to unravel mysteries of the cosmos” January 2015, setup René at ESTEC from Euronews from “Dark Matter dark energy, ESA and CERN to unravel mysteries of the cosmos” January 2015) 00 00 59 SOUNDBITE René Laureijs, Euclid Project Scientist, ESA (EN) I'm working on Euclid. That is a mission to map the universe and to explore the universe to see dark energy and also to see the dark matter content of the universe. For that we build a highly precise telescope.
TEXT
Euclid will use a 1.2-m diameter telescope to track the evolution of the Universe’s structure over three-quarters of its history. It will do so by taking hundreds of thousands of sharp images. (Animation ESA Euclid graphic Credit: ESA/C.Carreau) 00 01 29 SOUNDBITE René Laureijs, Euclid Project Scientist, ESA (EN) When we look at the sky and take a picture, we stop everything. We stop the reaction wheels and the only way to correct for possible drifts of the satellite is doing it with cold gas, because cold gas gives no disturbances to the images, the sharp image we want to achieve.
While Euclid will look at the vastness of the Universe, what will revolutionize our understanding is to couple its results with the study of the minuscule world deep within atoms. (Still image from ESA Euclid, and 3D dark matter map from ESA) 00 02 00 TEXT
In Geneva, CERN is about to restart the world's foremost particle accelerator, LHC, the Large Hadron Collider. Three years ago it spotted the Higgs Boson.

TEXT
The LHC has been upgraded. It is more powerful and is going to work at full power for the first time. It is hoped that it will open the door for the identification of dark matter. (Images filmed interior shots of LHC setup Luca Malgeri from Euronews “Dark Matter dark energy, ESA and CERN to unravel mysteries of the cosmos” January 2015) 00 02 32 SOUNDBITE Luca Malgeri, Physics coordinator for CMS experiment, CERN (EN) We know the questions, we have many questions to answer, and we are pretty sure that the LHC can answer some of them. We hope that it could answer all of them....it is not clear.

Euclid and LHC’s new missions are optimized to understand why the Universe is expanding at an accelerating rate, rather than slowing down due to the gravitational attraction of all the matter in it.
SOUNDBITE René Laureijs, Euclid Project Scientist, ESA (EN) The interesting thing is that we get more and more dark energy. Why? Because our universe is expanding, and with our expanding universe, we get more dark energy in our universe. Now the ordinary matter, so dark matter and normal matter, is not expanding, it’s diluting. So the fraction of dark energy compared to normal matter is increasing in time. When the universe expands more and more we get more volume of our universe, we get more space, and we get more dark energy.
So scientists for space and on the ground are ready to step into the unknown – an unknown that is crucial to understanding the future of our universe. (Images ESA July 2014 Venus express)
