Life found on Ryugu asteroid sample

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’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.
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!
Imagine that, for billions of years, you're a grain of material unbothered on asteroid Ryugu. All of a sudden, a spacecraft flies down, shoots you with a pellet to kick you up, and collects you, taking you back to Earth.
Asteroid Ryugu Sample Was 'Rapidly Colonised' By Earth Bacteria: Study
The sample from the asteroid Ryugu was overrun with Earth-based life forms after they were brought to the planet, scientists have concluded in a study.
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
Scientists make embarrassing discovery on asteroid sample they thought had signs of alien life
HOPES of finding traces of alien life in the universe have been scuppered yet again. And this time on asteroid Ryugu, a space rock with an orbit that passes between Earth and Mars. The Japanese
Earth Microbes Discovered in Asteroid Ryugu Sample, Raises Contamination Concerns
A Ryugu asteroid sample has been found contaminated by terrestrial microbes, raising questions about planetary protection.
Ryugu asteroid sample rapidly colonized by terrestrial life despite strict contamination control
Panspermia is the hypothesis that life can survive the transfer between planetary bodies as a secondary path for life to get started on planets throughout a solar system. The discovery of extraterrestrial life on asteroids or within meteorites would have profound implications for understanding the origins and distribution of life in the universe.
