This animation lets us plunge into a region of the sky occupied by Upper Scorpius and Ophiucus, where the largest group of rogue planets - at least 70, highlighted in the circles – has recently been discovered. Here we zoom in on one of them. Rogue planets do not orbit a star but roam freely on their own. Lurking far away from any star illuminating it, the rogue planet does not shine by reflected light; it instead emits a faint glow that can only be detected in infrared light. At around 40 seconds in the video we see this faint glow in a real image of a rogue planet.
