Operating on the theory that I am eventually going to finish writing my first book, I’ve begun doing research for my next large project, on early twentieth-century solar and radio observatories. Flipping through the articles on my desk, I ran across one from the 1960s about instruments for observing in the submillimetre wavelength range.[1] Reading it prompted me to wonder if there was any recent news about the Atacama Pathfinder Experiment (APEX) telescope. The search for news from APEX led me to today’s wallpaper.
Every time I visit the ESO website, I’m newly impressed with the online archive. I’ve commented on the image collection before, but the instrument documentation is superb as well. So, too, is the video archive. If you want to learn more about millimetre and submillimetre observations, check out the APEX trailer. Or, you can watch it just because it’s beautiful.
