This picture showcases a gravitational lensing system called SDSS J0928+2031. Astronomers are using NASA/ESA Hubble Space Telescope observations of this type of lensing to research how stars form and evolve in distant galaxies. Gravitational lensing can help astronomers study objects that would otherwise be too faint or appear too small for us to view. When a large object — such as a massive cluster of galaxies, as seen here — distorts space with its immense gravitational field, it causes light from more distant galaxies to travel along altered and warped paths. It also amplifies the light, m…
