A new video reveals what it takes to enable the UK research community to work with the huge amounts of data that the Rubin Legacy Survey of Space and Time (LSST) will capture.
The video produced by JISC focuses on the UK’s national research and education network (NREN) known as Janet. This network will play a critical role in transferring the huge quantities of data associated with the groundbreaking Rubin Observatory telescope when the survey commences in the near future.
Two members of the LSST:UK team – Agata Rożek, a Research Fellow in Astronomy at the University of Edinburgh, and George Beckett, Programme Manager at the EPCC (the UK's first National Supercomputing Centre and part of the University of Edinburgh) – feature in the film. They talk about how the Rubin LSST will transform astronomy research and highlight the significant role the UK is playing in the groundbreaking survey.
JISC is a not-for-profit organisation supporting higher and further education. One of its functions is to build and maintain the Janet Network. As the busiest NREN in Europe, Janet carries six petabytes of data each day. It connects 20 million users working in research, academia and education.
