66: Abusive Astronomy
Title text: Medium: Pencil on paper
An asterism is a pattern of stars that forms some sort of perceived shape in the night sky. Some of these are patterns used to name regions of the sky, as constellations. Modern astronomy organizes the sky into 88 constellations, but different cultures saw different patterns in the same night sky, going back at least as far as the Babylonians, and there are many other patterns and grouping of stars. The Pleiades (or Subaru), Orion's belt, and the Big Dipper are among the most common asterisms that we recognize today and are among the first taught to people with an interest in astronomy. The Pleiades is an open star cluster in the constellation of Taurus. It is a group of stars that formed from the same nebula and are moving together. Orion's belt comprises three stars that appear close in the sky, but are in fact at great distance from each other. The Big Dipper is part of the constellation Ursa Major. It can be used to help find the north pole star Polaris, which is an 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. The comic is presenting an especially aggressive way of introducing the night sky.
When astronomers in the Northern Hemisphere are showing stars to people, there will frequently be someone who points to the Pleiades and says, "There's the Big Dipper!" (both appear as a trapezium of stars, with a handle, though the Pleiades is much smaller). This gets frustrating about the 100th time that you encounter this error. So, this comic could show someone releasing their frustration on the misinformed public by pointing out that what they just pointed at is actually the Pleiades, then, pointing out that you can always locate the Pleiades by following the line of the stars in the belt of Orion, then, pointing out the REAL Big Dipper.
In the title text, Randall explains that he drew this comic as a line drawing on white paper, using only a pencil. The image was later inverted for publication.
As noted in the title text, the drawing for this comic was originally done in pencil, then inverted. Here is a re-inverted version of the file, to show (approximately) what the original drawing looked like.
Alternatively, Randall may be using sarcasm when saying that the medium is pencil on paper, since it would be incredibly impractical and nearly impossible to draw the uniform black background while leaving white gaps for stars (assuming it was not inverted).

- What the hell is wrong with you?
