Summary

Story summary

An animation shows two foreground galaxies gravitationally lens the supernova SN Winny, about 10 billion light-years away.
The animation shows the explosion lensed into multiple images, forming a bluish ring.
A high-resolution image from the Large Binocular Telescope (LBT) in Arizona captures the lens galaxies and five lensed copies of SN Winny.
These visualizations advance understanding of time-delayed light and contribute to research on the universe's expansion.

History

Historical Context

In 1919, Arthur Eddington led an expedition during a solar eclipse to observe light bending around the Sun, confirming Einstein's theory of general relativity. This pivotal moment established that massive objects can warp spacetime, influencing modern astrophysics. Recent observations of gravitational lensing around supernova SN Winny further validate these principles, enhancing our understanding of cosmic expansion and the universe's structure.
