Life found on Ryugu asteroid sample

Signs of Life in Asteroid Sample Turn Out to Be Something Embarrassing
Last year, researchers excitedly announced that they had found two organic compounds essential for living organisms in samples retrieved from an asteroid called Ryugu. The Japanese Space Agency's Hayabusa2 spacecraft obtained the samples from the space rock in 2019.
Samples of 'alien' asteroid Ryugu are crawling with life — from Earth
Scientists have found microorganisms crawling over a sample retrieved from the 200 million-mile-distant asteroid Ryugu. But they almost certainly came from Earth.
Asteroid Sample Was Quickly Taken Over By Life – In A Sterilized Environment!
Asteroid Ryugu was altered by water and contains organic molecules older than the Sun. The building blocks of RNA and Vitamin B3 have been found in its samples, together with polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, a molecule used in mothballs. Earthly bacteria don’t seem to care where the molecules originated from.
Japan's priceless asteroid Ryugu sample got 'rapidly colonized' by Earth bacteria
"The fact that terrestrial microbes are the Earth's best colonizers means we can never completely discount terrestrial contamination."
Life Found On Ryugu Asteroid Sample, But It Looks Very Familiar
Samples taken from the space-returned piece of asteroid Ryugu were collected and prepared under strict anti-contamination controls. Inside the cleanest of clean rooms, a tiny particle was
Life found on Ryugu asteroid sample, but it’s not as exciting as it sounds
A recent discovery made by scientists working with a sample of rock from outer space highlights one of the huge challenges that such work involves.
