The NASA/ESA Hubble Space Telescope captured a monster in formation while observing the eMACS J1353.7+4329 galaxy cluster, which lies about eight billion light-years from Earth in the constellation of Canes Venatici, a group of at least two galaxy clusters. Galaxies unite together to form a cosmic monster, a gigantic mass that acts as a gravitational lens. According to Wiese, gravitational lensing is an interesting example of Einstein’s general theory of relativity in action. A celestial body such as a cluster of galaxies is massive enough to warp space-time, causing the path of light around the object to be optically bent. Wide Lens Hubble’s Image of Galaxies Gravitational lenses can also zoom in on distant objects, allowing astronomers to observe objects that may be very faint and very far away. It can also distort images of background galaxies, turning them into streaks of light. The first signs of gravitational lensing appear as bright arcs mingling with a cluster of galaxies in eMACS J1353.7+4329. The data came from an observational project called Monsters in the Making, which used two Hubble instruments to observe five exceptional galaxy clusters at multiple wavelengths. These multi-wavelength observations are made possible by Hubble Wide Field Camera 3 and the Advanced Camera for Surveys. The astronomers behind the observations hope to pave the way for future studies of massive gravitational lensing using next-generation telescopes such as the James Webb Space Telescope.
