A follow-up observation by NASA's Hubble Space Telescope shows a field containing a microlensing event that was captured by the Optical Gravitational Lensing Experiment (OGLE) in 2013. This provides an example of how a Hubble image could be used to analyze future microlensing events spotted by NASA's Nancy Grace Roman Space Telescope.In gravitational microlensing, the gravity of a foreground object acts as a lens, magnifying and distorting the light of a background star when the two objects align in the sky.These images were created with Hubble data from proposal: 17776 (S. Terry).
Image Description: A field of stars, which are blue, white, and orange. A small region between the center and the right of the frame is outlined with a square box. Above it is a pullout of the outlined region, labeled “OGLE-2013-BLG-0341.” The pullout shows two fuzzy red orbs that are very close together, each of which are stars. One of the stars is labeled “lens”, while the other is labeled “background star.”
