Big Wheel galaxy challenges early cosmic formation theories
Sydney, Australia (SPX) Mar 19, 2025 An international collaboration led in part by Swinburne University of Technology has uncovered a massive spiral disk galaxy from the early universe, providing new insights into galactic formation. The discovery, made serendipitously through observations with the James Webb Space Telescope (JWST), revealed a disk galaxy from a time just two billion years after the Big Bang - roughly eleven billion years ago. Dr Themiya Nanayakkara, a specialist in galaxy spectral modeling, explained that this ... read more |
