Astronomers had the opportunity to see it for the first time in history red giant supernova. It was called 2020tlf and although the phenomenon itself is not new, observations in the case of this type of massive star, for example, Betelgeuse, are certainly possible.

The rest of the shots are under the video window:

This red giant is not in the Milky Way. It is a star located in the galaxy NGC 5731, not far from us About 120 million light-years away. Until recently, it was believed that these facilities were fairly peaceful. Supernova 2020tlf showed something completely different.

It should be noted that astronomers were first notified of the unusual activity of this star only 130 days before its transformation into a supernova. Observations were made possible using an instrument from the Mauna Kea Observatory in Hawaii.

At the same time, we invite you to listen to the latest episode of the podcast from a technical point of view. This time we talked about the growing electricity and nuclear energy prices near the Polish border and how many of us know that the reactor has been operating near Warsaw for decades.
