NASA spots ancient 'dead' galaxy shaped like Milky Way
Scientists using NASA's Hubble Space Telescope have found the first observational evidence that some ancient "dead" galaxies, where star formation stopped, evolve from a Milky Way-shaped disk into elliptical galaxies. The galaxy was captured using a phenomenon called gravitational lensing, where light from a distant galaxy is brightened and magnified by gravity of another galaxy in the foreground.
