Infographic of the Day: How the Antimatter-Hunting Alpha Magnetic Spectrometer Works

Scientists using a space-based device for analyzing cosmic rays say that they may have seen evidence of mysterious dark matter particles annihilating each other. Dark matter emits no light and hasn’t been seen previously by instruments, yet it seems to exist in a vastly larger amount than regular matter in the universe.

Follow up:

Unlike instruments on the ground, the Earth-orbiting Alpha Magnetic Spectrometer-2 investigates cosmic particles that do not survive the passage through the Earth’s atmosphere. AMS-2 is the largest and most powerful such instrument ever put in space.

A lack of anisotropy suggests that the energetic positrons are not coming from a single source in space. Together, this suggests to physicists that the energetic positrons may be coming from the annihilation of dark matter particles.
