A supernova will appear in the sky in the first few months of 2016,according to astronomers working on the Hubble Space Telescope.
The prediction is possible because they first saw the star explode in 2014 in a gravitationally lensed galaxy, which will make it visible again next year.
Gravitational lenses happen when a massive object (or objects such as a cluster of galaxies) magnifies and distorts the light of background galaxies.
In this case, the galaxy cluster is so massive that it deforms space and time so that it acts like a gigantic magnifying glass.
