Anonymous asked:
Space mom, do stars die? If so, what happens when they die? Have stars in our galaxy died and been noticed?
Yes! When stars die, they expand into massive red giants. Our own sun will do this in about 5 billion years, I believe? And when it does, the sun will expand to about where earth’s orbit is! After that, it ejects all of its outer layers into space (creating stellar nurseries for the next generation of stars). All that remains of the star is a White Dwarf. They are extremely small and dense.
When massive stars die, because of gravity and other physics, they actually explode into supernovae. We’ve recoded a bunch of these! We actually use them as a means to measure distances because supernovae (rather a specific subtype of supernovae) always have the same luminosity, so by measuring how bright a supernova was to us, we can tell the distance from it.
As a fun aside, due to the composition of our own star, it’s thought to be a 3rd generation star!

30 Doradus, located in the heart of the Tarantula nebula, is the brightest star-forming region in our galactic neighborhood. It is home to several million young stars; among which live the most massive stars ever seen. The nebula resides 170,000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way. No known star-forming region in our galaxy is as large or as prolific as 30 Doradus.
