They discovered that half of Earth\u2019s zinc came from asteroids that originated beyond the asteroid belt, which includes Jupiter, Saturn, and Uranus. This material is also thought to have provided other important volatiles, such as water. The discovery suggests that the outer Solar System played a larger role than previously thought in establishing Earth\u2019s inventory of volatile chemicals, and it may provide clues about the conditions required for life to emerge on Earth.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/live.staticflickr.com\/3242\/2282142797_5311b6f1ea_b.jpg\" ><figcaption class=\"wp-element-caption\">\u201c<a href=\"https:\/\/www.flickr.com\/photos\/26415674@N00\/2282142797\" target=\"_blank\" rel=\"noreferrer noopener\">Sphalerite (Zinc ore) and Galena (Lead ore)<\/a>\u201d by\u00a0<a href=\"https:\/\/www.flickr.com\/photos\/26415674@N00\" target=\"_blank\" rel=\"noreferrer noopener\">Orbital Joe<\/a>\u00a0is licensed under\u00a0<a href=\"https:\/\/creativecommons.org\/licenses\/by-nc-nd\/2.0\/?ref=openverse\" target=\"_blank\" rel=\"noreferrer noopener\">CC BY-NC-ND 2.0<\/a>.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>The study looked at 18 meteorites from various solar systems, 11 from the inner Solar System and 7 from the outer Solar System. The researchers compared the relative abundances of five different types of zinc in each meteorite to Earth samples. They discovered that, while carbonaceous bodies made up only about 10% of the Earth\u2019s mass, they supplied roughly half of the zinc.<\/p>\n\n\n\n<p>The researchers believe that material containing a high concentration of zinc and other volatile constituents is also likely to be relatively abundant in water, shedding light on the origins of Earth\u2019s water. The findings suggest that carbonaceous material played a key role in establishing Earth\u2019s budget of volatile elements, some of which are essential for life, according to the paper\u2019s first author, PhD candidate Rayssa Martins.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/live.staticflickr.com\/5614\/30124456694_8f3e474408_b.jpg\" ><figcaption class=\"wp-element-caption\">\u201c<a href=\"https:\/\/www.flickr.com\/photos\/28634332@N05\/30124456694\" target=\"_blank\" rel=\"noreferrer noopener\">Curiosity Mars Rover Checks Odd-looking Iron Meteorite<\/a>\u201d by\u00a0<a href=\"https:\/\/www.flickr.com\/photos\/28634332@N05\" target=\"_blank\" rel=\"noreferrer noopener\">NASA\u2019s Marshall Space Flight Center<\/a>\u00a0is licensed under\u00a0<a href=\"https:\/\/creativecommons.org\/licenses\/by-nc\/2.0\/?ref=openverse\" target=\"_blank\" rel=\"noreferrer noopener\">CC BY-NC 2.0<\/a>.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>The researchers intend to analyze rocks from Mars, which once had water, and the Moon next.
