Scientists may have discovered insight into the origins of life on Earth thanks to samples from the asteroid Ryugu.
Life on Earth may have come from space. At least, that’s the general belief, especially after recent observations of samples from the asteroid Ryugu. According to the researchers looking into the samples, Ryugu appears to contain several “prebiotic organics,” including a few different types of amino acids.
This isn’t the first time we’ve seen evidence that these building blocks for life came from space, either. Other samples taken from meteorites and other asteroids have also bolstered these beliefs by providing data on ancient water that has yet to be contaminated by our own planet. The findings discovered in the Ryugu samples are also consistent with those found in carbon-rich meteorites.
These are often the meteorites that have been exposed to the most water in space, giving us a better idea of what kinds of water might form in space so that scientists can determine how that water formed and from where it might have come from. Determining that could allow us to determine where water on Earth originated.. The researchers plan to compare the Ryugu sample with that taken from the asteroid Bennu when NASA’s OSIRIS-REx mission returns to Earth later this year.
