Today, February 14, 2020, is a very special day. It marks the 30th anniversary of the “Pale Blue Dot” image. This is a picture of Earth taken by NASA’s Voyager-1 after passing Neptune on its way out of the solar system. In this image, Earth appears as a speck of pale blue light. You could even say it looks like a mote of dust suspended in a sunbeam.
If you’re not familiar with the Hitchhiker’s Guide to the Galaxy (or H2G2 in short), you’re probably wondering why I’m listing 42 quotes from a series. It is not a multiple of 5 or 10, not a prime number, there is nothing special associated with it, so it’s kind of odd to list 42 quotes right? Well, the answer is at the end of the post. And if you read the Hitchhiker’s guide to the galaxy, which I strongly recommend, you may also develop a liking for this number.
