So Long, Herschel Space Observatory. The European Space Agency's infrared space telescope reaches the end of the line. By Andrew Moseman Published: Apr 30, 2013 10:23 AM EDT. Save Article.

PARIS — Ground controllers put Europe's Herschel Space Observatory to sleep Monday (June 17), turning off the infrared observatory after squeezing every bit of engineering value from the ...

The Herschel Space Observatory has returned over 35,000 scientific observations, more than 25,000 hours of data from about 600 observing programs and 2000 hours of calibration observations.

The Herschel observatory has a main mirror about 11.5 feet (3.5 meeters) across — nearly 1.5 times larger than Hubble Space Telescope — and was built to map the universe in the far-infrared to ...

ESA’s Herschel space observatory was launched on 14 May 2009 and, with a primary mirror 3.5 m across, is the largest, most powerful infrared telescope ever flown in space.

On April 29, the Herschel Space Observatory exhausted its supply of ultra-cold liquid helium coolant, required to do its most sensitive observations.

Astronomers knew this day would come. The Herschel Space Observatory has run out of coolant and ceased looking into the cold, distant universe. Without liquid helium to keep the instruments ...

While formally the Herschel Space Observatory did not discover this gravitational lens, it was the breakthrough Herschel performance that allowed the astronomers to measure the far-infrared ...
