All too often, our flesh cocoons can feel like vessels of anxiety and existential dread. But take heart, because new research confirms what science popularizers like Carl Sagan have said all along: humans truly are made of “star stuff”—and we’ve got maps to prove it.
Researchers found the center of the Milky Way to be the most abundant in CHNOPS elements. But perhaps the most validating aspect of the research is that these essential elements—found scattered across so many stars—also make up 97 percent of the mass of our bodies.
In addition to helping us learn more about ourselves, this new map could direct us to life beyond Earth, past or present.
“It’s a great human interest story that we are now able to map the abundance of all of the major elements found in the human body across hundreds of thousands of stars in our Milky Way,” Jennifer Johnson of Ohio State University said in a press release. “This allows us to place constraints on when and where in our galaxy life had the required elements to evolve, a sort ‘temporal Galactic habitable zone.’”
