May 13, 2019 - Telescope Double Header

Telescope Double Header  Ten years ago this week, an Ariane 5 rocket rose from the Guiana Space Center in French Guiana carrying two cutting-edge space telescopes for the European Space Agency. Herschel, named after English astronomer siblings Sir William and Caroline Herschel, ended operations in 2013 but was the largest, most powerful infrared telescope ever flown in space. Planck, named after German physicist Max Planck, was the first European space observatory whose main goal was the study of the Cosmic Microwave Background—the relic radiation from the Big Bang. Two instruments on Herschel worked in concert to create this infrared image of the W5 complex of cavernous molecular clouds and star-forming regions, located 6,000 light-years away in the constellation Cassiopeia.
