Scientists have theorized how galaxies evolve, but details in their early phase of formation remained shrouded in celestial clouds of mystery.
An international team, including Kyoto University and Saint Mary's University, has now discovered a baby galaxy made possible through the lens of the James Webb Space Telescope or JWST.
"Because of Einstein's gravitational lensing or warping effect applied through the JWST, we can see the galaxy twice, like a desert mirage, because light reaches us from two slightly different directions," says Marcin Sawicki at Saint Mary's University in Nova Scotia. The JWST data, obtained by the international team, revealed two images of the merging galaxies, produced by the bending of light around the mass concentration of the galaxy cluster MACS 0417 that lies between the observers and the merging galaxy pair.
