Remember back in the 90s and early aughts when SETI (Search for Extraterrestrial Intelligence) had those screensavers you could install that would process chunks of radio telescope data, looking for interesting signals? It would quietly download the data packets, process them, and send them back to SETI. That project has long since been canceled, but its successor is even cooler- SETI Live. The latest version of it just launched yesterday, and it literally allows you to visually analyze real data from the Allen Telescope Array. As I understand it, there are parts of the radio spectrum that are crowded by our own human-made signals. Even the most sophisticated computer software has a hard time distinguishing between something that’s manmade and something that’s extraterrestrial in origin, so they need human eyes to make the distinction. The project is part of Zooniverse, which has many other projects that allow the general public to take part in real scientific research and experiments. So sign yourself up and get to analyzing- you never know what you’ll find, especially now that they’re aiming the radio telescopes at stars known to have planets orbiting them!
Now sit back and enjoy this eye candy: yet another gorgeous timelapse video created from photos of earth at night taken from the International Space Station. I could literally watch stuff like this all day. There have been several of these created thus far, but this one just might be the best yet. It’s like crack for your eyes…
