3.5 APOD

Light Echoes from V838 Mon
Wow! This looks like a big furball dispersed in the night sky. Apparently, this V838 Mon's outer surface expanded so much that it suddenly became the brightest star in the entire Milky Way Galaxy. While there are material being expelled into space, the light echo is being reflected by distant rings around the star. This just looks so unreal!
