A global forensic team of astronomers led by Australia’s Macquarie University reconstructs using stunning James Webb Space Telescope images Around 2500 years ago, a star ejected most of its gas, forming the beautiful Southern Ring Nebula, NGC 3132, chosen as one of the first five image packages from the James Webb Space Telescope (JWST). A team of nearly 70 astronomers from 66 organisations across Europe, North, South and Central America, and Asia have used the JWST images to piece together the messy death of this star. “It was nearly three times the size of our Sun, but much younger, about 500 million years old. It created shrouds of gas that have expanded out from the ejection site, and left a remnant dense white dwarf star, with about half the mass of the Sun, but approximat...
