The rings of the ice giant Uranus are invisible to all but the largest telescopes — they weren’t even discovered until 1977. However, they are surprisingly bright in the new thermal images taken by the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT). The new images allowed astronomers for the first time to measure the temperature of rings particles: minus 321 degrees Fahrenheit (minus 196 degrees Celsius).
