Just a quick post to wish everyone seasons greetings. For those who celebrate Christmas, I hope you have a really enjoyable, and festive, day tomorrow (or, today, in some parts of the world). For those who have some spare time tomorrow, you might want to watch the launch of the James Webb Space Telescope (JWST), scheduled for 12:20pm UT. You can watch it live here. There’s also a site that illustrates how it’s going to be deployed.
In case you don’t know, this is the most expensive, and sophisticated, space observatory every launched by humankind. Consequently, tomorrow is likely to be a fairly nerve-wracking day for most astronomers. Let’s hope it’s a good one.
