The night sky in a telescope image looks like a photo taken through a fogged-up window: bright stars are visible, but everything faint drowns in a murky haze. That haze is noise — random interference from electronics, heat, and the atmosphere itself.

The giant galaxy cluster Abell S1063, lying 4 billion light-years away, works not just as a lens but as a gravitational well of time. Its mass bends space so sharply that photons from an era when the Universe was just 500 million years old slide along curved paths, like rays in slow motion, and converge on us magnified forty-three times.
