WHY WE’RE MADE OF STARDUST.

Human beings, along with everything else on Earth, are made up of recycled elements that originated from stars. This scientific fact, popularized by astronomer Carl Sagan, means that we are not unique or special in this regard. The elements that make up our bodies and the world around us were produced billions of years ago in the interior of stars. These elements are constantly being recycled on Earth, and even the planet itself was made from recycled elements. The origins of these elements can be traced back to nucleosynthesis, a process that occurred in the early universe and within stars. Stars produce heavier elements through nuclear fusion, and when they die, their material is dispersed into space, eventually forming new stars and planets. The atoms that make up our bodies come from various cosmic sources, including the Big Bang, dying low-mass stars, massive supernovae, merging neutron stars, exploding white dwarfs, and high-energy particle accelerators. While the term "stardust" is poetic, it accurately describes the clumping together of heavier atoms thrown out by stars into the interstellar medium, which can eventually form tiny dust grains. These grains can be found on asteroids in our Solar System and even on Earth in the form of meteorites. The birth of stars and the formation of planetary systems can be observed using tools like NASA's James Webb Space Telescope, which can study these processes by observing infrared wavelengths and determining the chemical composition of celestial objects.
