"Rare Gravitational Einstein Cross Unveils Quadruple Image of Distant Supernova"

An international team of researchers has discovered a distant supernova, named SN Zwicky, using gravitational lensing. The supernova, located 4 billion light-years away, is a type Ia supernova, which is used as a "standard candle" to measure distances in space. The discovery was made at the Zwicky Transient Facility (ZTF) in California, and further observations at the Keck Observatory and the Hubble Space Telescope confirmed the presence of four distinct images of SN Zwicky. Future observations using NASA's James Webb Space Telescope are planned to gain a clearer view of this unusual phenomenon.
