Washington, September 19 : A team of astronomers has discovered the least luminous, most dark matter-dominated galaxy known to exist.
The galaxy, called Segue 1, is one of about two dozen small satellite galaxies orbiting our own Milky Way galaxy.
The ultra-faint galaxy is a billion times less bright than the Milky Way, according to the team’s results.
But despite its small number of visible stars, Segue 1 is nearly a thousand times more massive than it appears, meaning most of its mass must come from dark matter.
