James Webb Telescope Uncovers 'Platypus' Galaxies: Inside-Out Formation Baffles Experts
- •NASA's James Webb Space Telescope (JWST) discovered nine mysterious cosmic objects dubbed 'Platypus' by University of Missouri researchers.
- •These 'Platypus' objects exhibit characteristics of both stars (point-like appearance) and galaxies (structure), baffling astronomers.
- •They are much dimmer than typical quasars and show narrow spectral fingerprints, suggesting they might be a new type of Active Galactic Nuclei or nascent galaxies.
- •A key baffling aspect is their 'inside-out' formation process, where stars develop from the center outwards, a peaceful process unlike typical turbulent galaxy formation.
- •These young galaxies, estimated to be around 200 million years old, challenge existing theories of how early galaxies formed and evolved.
Why It Matters: JWST's 'Platypus' galaxies, forming inside-out, challenge fundamental theories of early universe galaxy formation.
