MessageToEagle.com - What are the roles played by 'dark matter' and 'dark energy' in the Universe?

Why is the Universe expanding at an accelerating rate, rather than slowing down due to the gravitational attraction of all the matter in it?

NASA has joined ESA's Euclid mission, a space telescope designed to investigate the mysterious natures of dark matter and dark energy.

In 2020, Euclid's 1.2 m-diameter telescope and two scientific instruments will map the shape, brightness and 3D distribution of two billion galaxies covering more than a third of the whole sky and looking back over three-quarters of the history of the Universe.



"ESA's Euclid mission is designed to probe one of the most fundamental questions in modern cosmology, and we welcome NASA's contribution to this important endeavour, the most recent in a long history of cooperation in space science between our two agencies," said Alvaro Giménez Cañete, ESA's Director of Science and Robotic Exploration.

In cooperation with ESA, the US space agency NASA will provide 20 detectors for the near-infrared instrument, which will operate alongside a visible-wavelength camera. The instruments, telescope and spacecraft will be built and operated in Europe.

Already 40 US scientists have been nominated by NASA, to become members of the Euclid Consortium, who will build the instruments and analyse the science data returned from the mission.

"NASA is very proud to contribute to ESA's mission to understand perhaps the greatest science mystery of our time," said John Grunsfeld, associate administrator for NASA's Science Mission Directorate.
