New Hubble Image Shows Gravity Magnifying a Distant Galaxy - Interesting Engineering
We tend to think that light travels in a straight line, but this is not always the case in our universe, when strong enough, gravity can pull photons of light out of their trajectory. Hubble spotted a phenomenon known as gravitational lensing, which occurs when gravity bends light in super cool and interesting ways."The center of this image from the NASA/ESA Hubble Space Telescope is framed by the tell-tale arcs that result from strong gravitational lensing, a striking astronomical phenomenon which can warp, magnify, or even duplicate the appearance of distant galaxies," wrote NASA in its statement about its most recent image."Gravitational lensing occurs when light from a distant galaxy is subtly distorted by the gravitational pull of an intervening astronomical object.
