Going, going, gone: A NOAA weather balloon floats into the pre-dawn Antarctic sky over the Amundsen-Scott South Pole Station in this time-lapse photograph taken September 15, 2017. The balloon was carrying an ozonesonde -- instrument to measure ozone during NOAA's annual monitoring of the Antarctic ozone hole. Rising emissions of a strictly regulated chemical threatens recovery of the ozone hole, according to new NOAA research published in the journal Nature, May 16, 2018.
