Greenhouse Gases Discovered in Comets

Using data from the NEOWISE Space Telescope, astronomers have gained new insights into the dust and production rates for difficult-to-observe gases like carbon dioxide and carbon monoxide in comets. After its launch in 2009, NASA’s NEOWISE spacecraft observed 163 comets during the WISE/NEOWISE prime mission. This sample from the space telescope represents the largest infrared […]
