Red Dwarfs Will Be Here After Every Other Star Has Been Snuffed Out

Compared to other stars, red dwarfs are tiny and dim. But they make up for their unimpressive stature with their amazingly long lifespans, which stretch for trillions of years. Given that the universe is a mere 13.8 billion years old, it’s unsurprising that there isn’t a single known red dwarf that has entered the later stages of its life. These stars may also be our best bets for finding habitable planets. If the right conditions are met, a planet in orbit around a red dwarf could sustain life. Luckily, red dwarfs are the most common stars in space!
