With the help of an automated supernova-hunting pipeline and a galaxy sitting 2 bil-lion light years away from Earth that's acting as a "magnifying glass,'' astronomers have captured multiple images of a Type Ia supernova—the brilliant explosion of a star—appearing in four different locations on the sky. So far this is the only Type Ia discovered that has exhibited this effect.
(California Institute of Technology) An international team of astronomers has, for the first time, seen a cosmic magnification of the light from a class of supernova called Type Ia.
(American Association for the Advancement of Science) Galaxies bend light through an effect called gravitational lensing that helps astronomers peer deeper into the cosmos.
For the first time, astronomers have caught a type Ia supernova being magnified by more than 50 times and split into four images in the night sky thanks to gravitational lensing. The discovery, described in the journal Science, coul...
