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.
Sometimes, these distortions produce multiple images of the same object. Although they belong to the same galaxy, the images we see were not emitted at the same time. Because light travels at a finite speed, photons will take a different amount of time to travel around the massive object depending on the path they follow – with some routes taking longer than others.
The supernova explosion that we will see in 2016 is a re-run of the 2014 one, known as the Refsdal Supernova. It was generated in a galaxy nine billion light-years away, and the lens is created by a massive galaxy cluster, called MACS J1149+2223, five billion light-years from us.

The forward bulkhead and tunnel for Exploration Mission 1 undergoing paint priming, October 9, 2015. The EM-1 Orion capsule is being fabricated at the Michoud Assembly Facility in New Orleans, Louisiana. Seven major components are welded together to create the capsule’s pressure vessel. It then gets shipped to Kennedy Space Center in Florida where it undergoes final assembly and outfitting of key systems.
"Oh alright," the young adult responded. Tadashi had never really told Hiro that he wasn't allowed to because he really cared about his brother and only wanted the best for him. youneedsomeupgrades

Hiro woke, rubbing his eyes and staring at the dark ceiling, slowly sitting up and dangling his feet off the bed. His eyes scanned the room searching for his sound asleep brother. As his eyes found him he tiredly stood out of bed and almost drunkly walked over to the bed, setting his hands on the bed, closing his eyes. “Dashi.. Tadashi, you awake?”
