One day and the last star will die, and there will be darkness in the Universe forever.
This last star will most likely to be a red dwarf – a small and relatively cold star of the main sequence, a late K or M spectral class. What’s more – the Planets around it are one of the most suitable places where we could find extraterrestrial life. Or even a home of humankind before our own Solar System has become uninhabited.
What do we know about red dwarfs and why are our last hope? This interesting video of Kurzgesagt – In a Nutshell will tell you more on the topic.
