We tend to think that light travels in a straight line, but that’s not always the case in our universe, when it’s strong enough, gravity can pull photons of light out of their path. Hubble discovered a phenomenon known as gravitational lensing, which occurs When gravity bends light In wonderful and interesting ways.
“The center of this image from the NASA/ESA Hubble Space Telescope is framed by telltale arcs caused by strong gravitational lenses, an amazing astronomical phenomenon that can distort, magnify, or even double the appearance of distant galaxies.” NASA Books In her statement about her latest photo.
Gravitational lensing occurs when light from a distant galaxy is distorted by the gravitational pull of an interfering astronomical object. In this case, the relatively nearby galaxy cluster MACSJ0138.0-2155 has rendered an inactive galaxy remarkably distant — a known sleeping giant MRG. -M0138 which has run out of gas needed to form new stars and is located 10 billion light-years away.” Turns out, astronomers can use a gravitational lens as a normal magnifying glass. This, in turn, “allows them to examine objects such as distant dormant galaxies that would normally be very difficult for even Hubble to solve.”
Eight different infrared filters
In order to get this charming picture, researchers had to use Eight different infrared filters scattered across two of Hubble’s most advanced astronomical instruments: the Advanced Camera for Reconnaissance and the Wide Field Camera 3. These instruments were installed by astronauts during the last two service missions to Hubble and provide astronomers with exquisitely detailed observations across a large expanse of sky. and a wide range of wavelengths.”
