Motivated by theories of neutral naturalness, I will argue that Mirror Stars are a generic possibility in any hidden sector with analogues of Standard Model electromagnetism and nuclear physics. I will show that if there exists a tiny kinetic mixing between the dark and SM photon, Mirror Stars capture SM matter from the interstellar medium, which accumulates in the Mirror Star core. This leads to a spectacular and distinctive signature that could be discovered in optical and X-ray searches.
