Astronomers find the death cry of a star in a cluster long ago and not so very far away
Astronomers find the death cry of a star in a cluster long ago and not so very far away,A team of astronomers has found what may be the oldest known planetary nebula ever seen, and certainly one of the biggest. These structures are fleeting on a cosmic timescale, so finding one so old is extremely helpful in nailing down what happens as stars die. Bonus: It was confirmed to be in a bright, nearby stellar cluster, making it far easier to nail down several of its characteristics [link to paper].
