Saskatoon physicist discovers supernova from 35 million years ago

SASKATOON —
Each night time for a yr a high-powered robotic telescope in Saskatoon captures pictures of 600 close by galaxies over an eight-hour stretch, scanning for exploding stars often called supernovae.

Within the early hours of March 20, Saskatoon’s PROMPT-USASK Skynet robotic telescope discovered its first one.

“It was enjoyable to lastly get a discovery,” stated Daryl Janzen, educational assistant in physics and engineering on the College of Saskatchewan.

Colleagues in Chile and Australia confirmed the invention, and Janzen added the supernova occurred in a galaxy 35 million mild years away.

“The supernova really occurred 35 million years in the past, up to now, however we’re solely simply seeing it now as a result of it’s taken 35 million years for the sunshine from this explosion to lastly attain our telescope,” Janzen stated.

By means of the robotic telescope the exploding appears like a tiny level of sunshine within the distance. Janzen stated this was a sort two supernova, which means it marked the top of the lifetime of an enormous star by imploding.

Janzen stated he predicts the star captured on the telescope was a minimum of eight occasions the dimensions of our solar, however it could possibly be as much as 100 occasions extra huge.

The supernova was named SN 2021gmj. It’s the primary supernova found by the college’s robotic telescope which was put in in April 2020 at Sleaford Observatory north of Colonsay.

The telescope is a part of the worldwide astronomy community known as Skynet, Janzen stated.

Janzen stated supernovae assist astrophysicists higher perceive stellar evolution and the evolution of galaxies.

“Additionally, as a result of supernovae are so brilliant that we are able to see them at very far distances, there are necessary functions to distance measurements that contribute to our understanding of the evolution of the universe as a complete,” he stated.
