Old TVs, new Spot, Old Rocket, and Moon Pictures

Inspired by a comment from The Thomas, here is an article about the a working 1936 TV in the UK. Let that be a challenge to you! I was amused by the fact that it only had one channel because there was only a single (state owned) station in the entire UK, so it needs two converters to get over-the-air transmissions, and by the comments from the grandson of John Logie Baird (UK television inventor). I knew him from an old book (something about "electrons go to work") in my collection.

The article also has an extensive comments section, where various people posted the ancient things they have that still work. Reminds me of the refrigerator my parents have in the old house, which I think is older than I am.

Other news of note includes a new "spot" on Jupiter (possibly from an impact, but a "dark mark" could come from a Death Eater attack), and some older followup stories about Apollo:

The NASA article gives important details on the resolution per pixel (about four feet) and how the long shadow (due to a low sun angle) makes it easier to spot the lander. Imagine what we will see when the resolution improves by more than a factor of 2 after they circularize the LRO orbit later this year!
