Physicists solve puzzle about ancient galaxy found by Webb telescope

Surprisingly, an Einstein ring is associated with this galaxy. That's because JWST-ER1g acts as a lens and bends light from a distant source, which then appears as a ring—a phenomenon called strong gravitational lensing, predicted in Einstein's theory of general relativity.
