SMRTR summary
Astronomers have confirmed the existence of CDG-2, a galaxy located 300 million light-years away that consists of 99.9 percent dark matter with only four visible star clusters. Using combined data from Hubble, Euclid, and Subaru telescopes, researchers detected an extremely faint glow proving these clusters belong to the same dark matter-dominated galaxy, making it the first galaxy detected only by its brightest fragments and providing a natural laboratory for studying dark matter's mysterious properties.
