"Rare Gravitational Einstein Cross Unveils Four Copies of Distant Supernova, While a Bright Supernova Illuminates the Night Skies"

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. The arrival time of the four images at Earth was almost simultaneous, despite traveling along different gravitational paths. Future observations using NASA's James Webb Space Telescope are planned to gain a clearer view of this phenomenon.
