Hubble Discovers an Unprecedentedly Massive Galaxy Through a Gravitational Lens
Astronomers have just made an incredible discovery with the help of the Hubble Space Telescope. Using the power of a “gravitational lens,” they’ve managed to detect the light of a distant galaxy that is 10 times more massive than the Milky Way — something that would otherwise have been impossible to do. This is the first time that a gravitational lens has been used to detect such a massive galaxy, and it could lead to a better understanding of dark matter and the evolution of galaxies.
