“We had no idea that the white dwarf was pulsating when we started the work,” said the paper’s first author, Steven Parsons of the University of Sheffield, in an email to Astronomy. Now, based on a new finding made by researchers from the University of Sheffield, we may be able to unlock even more details about our Sun’s fate.Īstronomers studying a binary white dwarf system have found a new pulsating white dwarf. But that's so far away it's essentially, by human standards, "forever".Over the course of its life, our Sun will go through several stages of stellar evolution, eventually ending its life as a white dwarf. Eventually, as the universe approaches heat death, none of this will matter. So life could only flourish in the boundaries between the perma-day and perma-night. But it would be hard: the closeness of the star would mean that one side of the world would be permanently in a super-hot daytime, and another would be stuck in a super-cold nighttime. If we found a planet that orbits a white dwarf close enough, it's possible that human life could continue. We couldn't live on Earth, because our planet is far too distant to get any warmth from our sun after it becomes a white dwarf. But to do so, our way of life would have to change dramatically.
It's possible, as per this video from Kurzgesagt, that humans could live on in the era or white dwarfs. White dwarfs are super dense, super hot tiny balls comprised of a star's former core.
But before then, all of the stars in the universe will reach their final form, which for 97% of them, including our own sun, means becoming white dwarfs (the other 3% explode into supernovas). If you're worried about climate change, rising authoritarianism worldwide, or widespread automation replacing workers, take heart-in a few trillion years (ok, more like 10 10 3 years) heat death of the universe will occur, leaving the entirety of the known universe a black, freezing expanse of nothingness.
