JWST: A Dance of Dwarf Galaxies

JWST: A Dance of Dwarf Galaxies – The Cosmic Waltz Space is often viewed as static and silent, but the James Webb Space Telescope reveals that it is alive with movement. You are looking at a gravitational dance between two dwarf galaxies, NGC 4490 and NGC 4485, captured in unprecedented detail. Right now, 24 million light-years away in the constellation Canes Venatici, two dwarf galaxies are finishing a cosmic embrace that began long before dinosaurs walked the Earth. NGC 4490, the larger dancer, pirouettes through space. NGC 4485, its smaller companion, trails a luminous ribbon of gas—a bridge forged by gravity itself, connecting two island universes in an intimate gravitational waltz. And James Webb just captured the entire choreography. Roughly 200 million years ago, these two celestial
