Earth Microbes Discovered in Asteroid Ryugu Sample, Raises Contamination Concerns
A study has confirmed that terrestrial microbes colonised a Ryugu asteroid sample after its return to Earth in 2020. The micro-organisms were found to proliferate upon exposure to Earth's atmosphere, raising concerns over contamination risks in planetary exploration. Published in Meteoritics & Planetary Science, the findings underline the need for ...

Phosphorus Grains in Ryugu Samples Offer Insights into Earth’s Early Life Chemistry
Scientists have discovered phosphorus-rich grains in samples from the asteroid Ryugu, brought back by Japan’s Hayabusa2 mission. These grains, thought to have come from the outer Solar System, may have interacted with early Earth’s water, releasing essential nutrients like phosphorus and nitrogen. This interaction could have played a role in th...

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 Sp...

Building Blocks of Life Discovered on Asteroid Located 200 Million Miles Away From Earth
Scientists studied materials taken from the asteroid by the Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 probe, which landed on Ryugu in 2018. The spacecraft retrieved 0.2 ounces (5.4 grams) of material from the asteroid's surface and subsurface in 2019, stored it in an airtight container, and returned it to Earth.
