New Study Proves: We Are Really Made Of Stardust

This seems like a scene from a bizarre and outrageous sci-fi movie that already destroyed the main plot by its incredulity. The truth behind the origins of humanity is far from what we originally thought. For many years, the ones who have strayed from the path have believed that humans are essentially made of stardust – which many will still think incredulous now.


However, recent findings from a survey of 150,000 have confirmed these scientists who believed in the far-fetched – and it proved many wrongs, and them correct. In the survey proved the cliche to be true – about 97% of the same kind of atoms that make us human is those that are found in the stars – and these elements are actually even more prevalent in them, as stars are in the center of the universe.



CHNOPS – what runs through your head when this abbreviation is used? It actually means carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Why are they so important? If one were to think properly, one would realize these elements are the building blocks of life – the ones that are essentially vital to the way we live, and the reason humanity can find life in the first place.


How exactly do you dissect a star, an eternal material that seems to cease to exist and impossible to contain? Scientists have come up with the most brilliant way of researching and dissecting stars – which is a method called spectroscopy. Each element in a star emits different wavelengths, which are then determined and matched to each star’s light spectrum to determine the material.

The researchers used measurements from the Sloan Digital Sky Survey’s (SDSS) Apache Point Observatory Galactic Evolution Experiment (APOGEE) in Mexico. The wonderful thing about APOGEE is that it is able to peer through dust – a breakthrough in science. Sloan researchers have since released a statement, claiming: “This instrument collects light in the near-infrared part of the electromagnetic spectrum and disperses it, like a prism, to reveal signatures of different elements in the atmospheres of stars. A fraction of the almost 200,000 stars surveyed by APOGEE overlap with the sample of stars targeted by the NASA Kepler mission, which was designed to find potentially Earth-like planets.”

However, one all-important question comes to mind: What makes a human, and what makes a star? The thing is, even though humans share many similar elements with stars down to the atomic level, the mass in which we are made up of that particular element is different. For instance, humans are made up of 65% oxygen, whereas oxygen does not even account a 1% in a star’s mass. This, in fact, has also led to another amazing discovery: the proportion of each element of life differed depending on which region the star was from.

This allows researchers to find out more about our galaxy – and just where humanity came from, and any other secrets the stars may hold. The catalog of chemical abundances is available at
