McDonald Observatory leaders and supporters, along with representatives from an international group of partner universities and research institutions, are gathering on a remote mountaintop high in the Chilean Andes today to celebrate groundbreaking for the Giant Magellan Telescope.
A team led by Andrew Mann has confirmed the existence of a the youngest 'super-Neptune' yet — a planet about five times the size of Earth. The discovery lends unique insights into the origin of planetary system architectures.
