Astronomers discover supernova explosion through rare 'cosmic magnifying glasses'

Read more at In this video: Zooming in to supernova Zwicky: starting from a small portion of the Palomar ZTF camera, one out of 64 “quadrants”, each one containing tens of thousands of stars and galaxies, the zoom in takes us to detailed explorations carried out with the larger and sharper VLT and Keck telescopes in Chile and Hawai'i respectively. On the best resolved Keck images, the four nearly identical “copies” of supernova Zwicky can be seen. The multiple images arise due to the warping of space caused by a foreground galaxy, also seen in the center and approximately half-way between the site of the supernova explosion and Earth.
