The Herschel Space Observatory was a European Space Agency-built and -operated space observatory, active from 2009 to 2013. It was studying the Universe by the light of the far-infrared and submillimeter portions of the spectrum revealing new information about the earliest, most distant stars and galaxies, as well as those closer to home in space and time. It has also taken a unique look at our own solar system. Herschel Space Observatory was the largest infrared telescope ever launched, carrying a single 3.5-metre mirror.In the afternoon of April 29, 2013 Herschel ran out of liquid helium. To declare end-of-helium (EoHe) a number of key temperature sensor upper limits had been defined, and with two of them attained, EoHe had formally been reached. Herschel has made over 35000 scientific observations, amassing more than 25000 hours of science data from about 600 observing programmes. Finally on June 17, 2013, engineers for the Herschel space telescope sent final commands to put the decommissioned observatory from its orbit around the L2 point 1.5 million kilometres from the Earth into its “graveyard” heliocentric parking orbit.Last week we decide to follow-up the "Herschel Space Observatory" in his new orbit using the Faulkes Telescopes (2.0-m f/10.0 Ritchey-Chretien ...
