The examination of a sample brought from asteroid Ryugu in outer space turned exciting for scientists when they found it had life forms on it. However, soon the excitement died down when they found that the microbes on the sample had actually originated on Earth.
The sample was brought to Earth in 2020 after being gathered in 2019 during Japan’s Hayabusa2 mission.
Scientists treated the Ryugu samples with great care and kept them under strict contamination controls, limiting their chance of contamination.
