Astronomers spot rare double-gravitational lens formed by two aligned galaxies
SMRTR summary
Astronomers have discovered two perfectly aligned galaxies acting as a compound gravitational lens, creating a rare "Einstein zig-zag" effect. This unique configuration could help refine calculations of the Hubble constant and potentially resolve debates about the universe's expansion rate, though complex data analysis will likely take over a year to complete.
