Abusive Astronomy

Title text: Medium: Pencil on paper

Explanation

A constellation (more formally known as an asterism) is a pattern of stars which form some sort of perceived shape in the night sky. Different cultures have created different patterns from the same groups of stars going back at least as far as the Babylonians. The Pleiades, Orion's belt and the Big Dipper are among the most common constellations that we recognise today and are among the first taught to people with an interest in astronomy. The Big Dipper can be used to help find the north pole star Polaris and this can be a useful aid to night time navigation.

During planetarium tours, the tour guide will point out popular constellations and stars, sometimes they will ask a question to get the audience involved in the presentation. Usually these people are big on showing the wonder of the galaxy and are all smiles, but people have bad days. Randall might also be reflecting on the fact that the grouping and naming of constellations varies from culture to culture and how easy it is for an expert to fail to realise that what is basic knowledge to them might be completely new to someone else.

Discussion

Actually, I don't quite get it. Since it's one of the early xkcd strips, it is somewhat different from the latter ones. I would suppose he is making fun on how it is impossible to guess what the constellations are, as they just look like a bunch of stars clumped together (definitely not like a belt). 35.13.220.113 03:52, 25 October 2012 (UTC) NariOX The first one looks like a certain male part, the second looks like a pencil, I can't figure out the last one though...
