XKCD comic, described below.
Transcript

[In a black panel a large orange Sun-type sun is shown, depicted as it might look when viewed through solar eclipse glasses. A pattern in the form of a "check engine" light (as displayed on a car's instrument panel) is shown on the surface of the Sun, in the bottom right quarter. The pattern has a pictogram of a motor on the top with text below it, both in orange inside a black square, matching the orange shading of the rest of the Sun.]
