We are all stardust who came from very far corners of the universe.

Our origins are much less local than we thought,

“Science is very useful for finding our place in the universe,” said Daniel Anglés-Alcázar, an astronomer at Northwestern University in Evanston, Illinois. “In some sense we are extragalactic visitors or immigrants in what we think of as our galaxy.”
The researchers ran supercomputer simulations to watch what happened as galaxies evolved over billions of years. They noticed that as stars exploded in smaller galaxies, the blasts ejected clouds of elements that fell into neighbouring, larger galaxies. The Milky Way absorbs about one sun’s-worth of extragalactic material every year.
Earth is showered with such inter galactic happenings
