Just a few days shy of its four-year anniversary, the Herschel Space Observatory has exhausted its supply of liquid helium coolant, and officially 'closed its eyes' on the universe, April 29.
Researchers around the world, and at the University of Lethbridge, now have a massive data collection, years of future research projects, and remarkable images that show unique star births sand star formations, galaxies and a host of other dramatic developments in the origins of the universe.
The pioneering space imaging mission logged more than 35,000 observations and generated more than 25,000 hours worth of science data from about 600 observing programmes. A further 2,000 hours of calibration observations will also contribute to the rich dataset.
