New laboratory experiments are working to produce that color \u2014 and others found in Jupiter\u2019s stormy cloud tops \u2014 here on Earth, and researchers have found that radiation and temperature play key roles in changing the color of some of the transparent material found in the clouds.<\/p>\n<p>A primary suspect in coloring Jupiter\u2019s clouds is ammonium hydrosulfide, a type of salt. Formed by ionized ammonium and bisulfide, it quickly decomposes at typical atmospheric conditions and temperatures on Earth, making it challenging to investigate its properties.<\/p>\n<p>\u201cModels predict that ammonium hydrosulfide is the third most abundant cloud component [on Jupiter], behind ammonia and water,\u201d <strong>Mark Loeffler<\/strong>, an astrochemist at Northern Arizona University, told Space.com by email.
