OGLE-2017-BLG-0604L b is a fascinating exoplanet discovered in 2020 by the Optical Gravitational Lensing Experiment (OGLE) using the clever technique of microlensing, which detects distant worlds by the way their gravity bends light from stars behind them. This little cosmic gem orbits the star OGLE-2017-BLG-0604L and was spotted thanks to the trusty OGLE CCD Array, a powerful ground-based telescope setup. Although specifics about its size and makeup remain a mystery, its discovery showcases the ingenuity of astronomers hunting for planets far beyond our cosmic neighborhood. OGLE-2017-BLG-0604L b might not have a fancy proper name yet, but it’s a shining example of how we keep uncovering new and exciting worlds out there in the galaxy!
