Space Telescope Live

What Space Telescope Live actually is

The observing schedules for Hubble and the James Webb Space Telescope are public, and this site renders them as a live view of the current target: which object, which instrument, which proposal and whose research it belongs to. A countdown runs to the next observation in the queue.

Why it is worth your time

Reading the name of the scientist whose proposal is executing right now, on a telescope a million miles away, makes the queue for observing time feel like a real place.
