My definition of gravitational lensing is two solar bodies passing in a way to create a reflection of one solar body -- something like an echo sight? So, according to this news item from Science Daily, do we have 12 galaxies there or 1 galaxy that is being reflected 11 time? Or, more likely, are my definitions wrong? Quote: Astronomers using the NASA/ESA Hubble Space Telescope have observed a galaxy in the distant regions of the Universe which appears duplicated at least 12 times on the night sky. This unique sight, created by strong gravitational lensing, helps astronomers get a better understanding of the cosmic era known as the epoch of reionisation.
