New observations from JWST and other telescopes are revealing how galaxies, planets, and cosmic structures form across the universe's history. Recent discoveries challenge existing formation models while showing how quasars suppress star birth and how collisions create planetary rings.
·JWST detects the most distant gravitational lens yet, a galaxy cluster that contradicts current cosmic formation theories
·Direct imaging of the cosmic web maps the universe's hidden highways of matter connecting galaxies
·Polycyclic aromatic hydrocarbons observed at cosmic noon provide insights into galaxy assembly during peak star formation
·Quasars act as cosmic blowtorches, shutting down star formation in early universe galaxies
·Celestial collisions similar to Saturn's ring-forming event shaped planetary systems
