Supernova Requiem Returns in 2037 (or So) - The Cosmic Companion 15 Sept. 2021

A supernova seen in 2016 is set to appear again in 2037. And, this appearance could help us better understand the Universe.

Supernova Requiem, first seen by Hubble five years ago, should reappear in 2037. And, it could carry a deep secret of the Universe.

Long ago, a star 10 billion light years from Earth erupted in a magnificent explosion. During a journey of 100 million centuries, some of this light encountered a massive galaxy cluster. The behemoth gravitational well of this cluster tore the path of the light into four different paths. This effect, called gravitational lensing, was first predicted by Albert Einstein more than a century ago.

Three of those channels of light from Supernova Requiem were spotted by the Hubble Space Telescope in 2016. Images from each path of light varied in brightness and color, representing a different point in time following the explosion.

However, the fourth stream of light — traveling the longest path around the collection of galaxies four billion light years from Earth — has not yet arrived at our home world. In 2037, that will change.
