I hated VHS, and yet I love this nostalgia.
I found my box of old audio cassette last week, but don’t have a player. Luckily I have an old car with a cassette deck. It’s been awesome.

An impact crater on a speck of dust. Yep.
Via sirmitchell:
Space is nuts. This is moon dust under a microscope.
The crater near top left, being only a few thousandths of an inch across, was probably made by a meteoroid only a tenth of a thousandth of an inch in diameter. On the Earth, such micrometeoroids would be slowed to negligible speeds by our atmosphere, and simply float to the surface. But the absence of a lunar atmosphere allows them to hit the surface at tens of thousands of miles per hour.
