To study the most extreme objects in the Universe, astronomers sometimes have to go to some extreme places themselves. Over the past several months, a team of scientists has braved frigid temperatures to set up and observe with a new radio telescope in Greenland. Taking advantage of excellent atmospheric conditions, the Greenland Telescope is designed to detect radio waves from stars, star-forming regions, galaxies and the vicinity of black holes. One of its primary goals is to take the first image of a supermassive black hole.
