Six years from now, a satellite will be launched to carry out the Euclid mission. Euclid is a large collaborative initiative of more than 1000 researchers from over 100 institutes in Europe and the USA who seek answers to some of the most burning questions in modern astronomy and physics: what is the nature of dark energy and dark matter, and what role they play in the accelerating expansion of the universe. Target leads the national effort in solving one of the most challenging aspect of the project – the development of a massive distributed system for storage and processing of the Euclid data. A national Science Ground Segment Data center started its operations at the Donald Smits Center for Information Technologies (CIT) and will collaborate closely with ESA to achieve the demanding goals for the data handling of the mission.
In early 2013, a team of Dutch partners including Target set up the NL Euclid Science Data Center (NL-SDC) to support the Euclid mission after they received over 5 million euro funding from NOVA, SRON and the University of Groningen. The NL-SDC is located at the CIT in groningen and uses the hardware facilities and expertise of the Target project. Though 2020 might seem to reside quite far in the future, the NL-SDC is already bursting with activity. Members of the Target team are collaborating with ESA on the development of the Euclid Archive System. This system will manage tens of petabytes of space and ground-based data from the mission distributed over at least eight large data centers in Europe. A prototype of this archive, based on components of the Astro-WISE system developed by OmegaCEN/Target, is already operational and provides services to the Euclid Consortium.
To study dark matter and dark energy, Euclid will image over 10 billion galaxies over a period of 6 years. This data will be complemented by ground-based surveys measuring distances to these objects. The total volume of the Euclid data is expected to be about 30 petabytes. In addition to archiving these massive data volumes, the Euclid Archive System should efficiently process and analyze these heterogeneous datasets to extract reliable information about the structure and evolution of dark matter and dark energy. This makes the design and implementation of the system one of the main challenges of the mission that takes up about half of the resources of the European consortium. “The new NL Euclid Science Data Center and our active role in the Euclid Archive System is a great opportunity for the RUG and the North of the Netherlands to position themselves as knowledge hubs for large Big Data projects”, says the Target lead Prof. Edwin Valentijn.

Dick Jager isn’t one to give up easily. Since the late 1990s, he has been working to make the University of Groningen more sustainable. His journey has been a struggle, with the road often peppered with obstacles. But now things are going his way....
The Cabinet’s decision, based on the advice of the Van Rijn committee, will have disastrous consequences for the University of Groningen as a broad-based classical university.
The University of Groningen (UG) holds the 114th place in the QS World University Rankings. The QS Ranking is an influential ranking list of almost 1,000 universities worldwide. Last year the UG held the120th place.
