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].
