Exceptionally rare gravitational lens produces five images of a distant supernova
The explosion of the supernova Winny, observed roughly 10 billion light‑years from Earth, may provide new insights into the rate of the universe’s expansion.
FINCA fellow Stefan Schuldt detected Winny’s light passing through a gravitational lens. Further observations were carried out using the Nordic Optical Telescope, maintained by Finland and the other Nordic countries. It was confirmed that the object is a rare supernova more than 10 billion light-years from Earth.
