But to astronomers, seeing those beautiful colors light up the night sky—like they will across the world on New Year’s Eve—means something entirely different.

Watch materials scientist Ainissa Ramirez explain how this is possible. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3943140/science-fireworks-galaxy-astronomy/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3943140/science-fireworks-galaxy-astronomy/"},"headline":"The Science of Why We Love Fireworks","datePublished":"2015-07-01T14:57:32.000Z","dateModified":"2023-12-13T05:32:27.000Z","description":"How do fireworks work?
