Another hobby of mine I wanted to share. Also gives perspective on just how small and fragile we are.
So my research stopped at VY Canis Majoris because it is in fact the largest known STAR in the Milky Way. I used the vid above because of it's graphics but Shadron Purple Hyper giant and VY Masses Majoris actually don't exist or have not been located but it's reasonable to conclude they could reside somewhere on the outskirts of the Andromeda galaxy. I will share with you later on the possibility of the Milky Way and Andromeda galaxies colliding which will happen long after we're all gone.
Below is the artist conception of the HyperNova of VY Canis. The extreme gamma ray bursts from the death of Stars this size are spectacular as shown in the vid below.
For those that want to explore further there are organizations you can participate in such as:
The Planetary Society and SETI :
