Asteroid discovery suggests ingredients for life on Earth came from space

Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago. Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Space Agency's Hayabusa2 spacecraft from two sites on Ryugu in 2019. Uracil is one of the chemical building blocks for RNA, a molecule carrying directions for building and operating living organisms. Niacin, also called Vitamin B3 or nicotinic acid, is vital for their metabolism.
