Explanation
This comic is structured as a "Relationship Tip" and reads: "If you ever make a confession to an astronomer, do it with a poster." Below the text is an image of the entire Milky Way galaxy (or a similar spiral galaxy) rendered in detail, with a tiny label pointing to one location that reads: "Places where I cheated on you."
The joke is that if your partner is an astronomer, you can exploit the sheer scale of the universe to make your infidelity seem trivially small. By presenting your confession on a poster that shows the entire galaxy, the places where you cheated appear as an insignificant speck compared to the vast cosmos. The humor relies on the idea that an astronomer, accustomed to thinking in cosmic scales, might appreciate (or at least be distracted by) the sense of perspective -- even though the betrayal is exactly the same regardless of how you present it.
The votey extends the gag with text reading "But don'''t let him zoom in..." and shows that zooming into the marked location reveals a "Burger King," suggesting the cheating happened at a specific, hilariously mundane fast-food restaurant. This deflates the grand cosmic framing with an absurdly unromantic detail.
