Where’s the Dark Matter? Look for Suspiciously Warm Planets

Physicists calculated that these mysterious particles will betray their location with heat. To prove it, they’ll need the most powerful telescopes in the cosmos.

> For that reason, Leane is suggesting that we look for them in the Milky Way’s vast collection of exoplanets, or those outside our solar system. Specifically, she thinks we should be using large sets of gas giants, planets like our own Jupiter. Dark matter can get stuck in planets’ gravities, as if in quicksand. When that happens, particles can collide and annihilate, releasing heat. That heat can accumulate to make the planet piping hot—especially those near a galaxy’s dense center.

Thinking laterally, Jupiter and Saturn are already suspiciously warm. They radiate significantly more heat than they recieve from the Sun, and the reasons aren’t well understood.

So look in our own backyard first?
