" NASA on Wednesday released an amazing infrared map of the entire sky — at least as much of the infrared sky as we can see using the best tool that was available for the job: NASA’s Wide-field Infrared Survey Explorer (WISE), an unmanned satellite orbiting the Earth that was launched in 2009 and completed its surveying in February 2011.
It took scientists another year and change to sort through WISE’s data — some 2.7 million images, each one snapped every 11 seconds — and put together the incredible map of the infrared sky.
“This data release completes our fundamental objective for WISE: to provide a sensitive infrared all sky survey,” wrote Peter Eisenhardt, WISE’s project scientist, in an email to TPM.
Specifically, the all-sky map includes 18,000 of the most representative images snapped by WISE and stitched together into a single, high-res image showing three of the four wavelengths of infrared light that WISE was able to detect. See the image in various resolutions, zoomable, and with annotated features of the known Universe here at the official WISE website."
