About these feeds: These images are from observatories around the world. Most of them are webcam images that are near-real-time, typically captured within the last 5 - 15 minutes. At this stage the only live video stream is from the Subaru telescope.
Some of these cameras show only night-time views, some only day-time, some show both. The quality and reliability vary a lot. Occasionally you'll see views that are either broken or haven't updated for a while.
