Photo of the Day – February 22 (2018)

Early in the morning on September 20, 2016, Victor Buzot watched the spiral galaxy NGC 613, testing a new camera for his telescope. Having studied a set of photographs with a short exposure, which he had just made, he noticed something strange on the outskirts of the Galaxy – a bright spot of light. It turned out that the astronomer photographed the birth of the supernova.

Astronomers from the Institute of Astrophysics of La Plata recognized the importance of discovering Victor Buzot and called on astronomers around the world to study this site in the sky.

The state of the supernova, recorded in Buzot’s photographs, shows the moment when the exploding star has already thrown out most of its hydrogen envelope. Using theoretical models, scientists estimated that the host star originally had a mass about 20 times the mass of the Sun, but probably at the time of death it was about five solar masses. The researchers say that the rest of this mass was absorbed by the supernova.
