Gravity is so much a part of our daily lives that it is all too easy to forget its awesome power but on a galactic scale, its power becomes both strikingly clear and visually stunning. This image was taken with the NASA/ESA Hubble Space Telescopes Wide Field Camera 3 (WFC3) and shows an object named SDSS J1138+2754. It acts as a gravitational lens illustrates the true strength of gravity: A large mass a galaxy cluster in this case is creating such a strong gravitational field that it is bending the very fabric of its surroundings. This causes the billion-year-old light from galaxies sitting behind it to travel along distorted, curved paths, transforming the familiar shapes of spirals and ellipticals (visible in other parts of the image) into long, smudged arcs and scattered dashes. Some distant galaxies even appear multiple times in this image. Since galaxies are wide objects, light from one side of the galaxy passes through the gravitational lens differently than light from the other side. When the galaxies light reaches Earth it can appear reflected, as seen with the galaxy on the lower left part of the lens, or distorted, as seen with the galaxy to the upper right. This data were taken as part of a research project on star formation in the distant Universe, building on Hubbles extensive legacy of deep-field images. Hubble observed 73 gravitationally-lensed galaxies for this project.
