Life found on Ryugu asteroid sample

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.
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.
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."
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.
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.
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
A sample from Ryugu asteroid is teeming with life — but it’s not aliens
A team of researchers led by Matthew Genge at Imperial College London confirmed that the asteroid has organic molecules; it confirmed that the samples actually have signs of life — but this life doesn’t come from 100 million miles away. It comes from Earth.
Ryugu asteroid samples indicate damage from microscopic meteoroid bombardment
Asteroids are remnants of the formation of our solar system, and while many can be found within the asteroid belt between the orbits of Mars and Jupiter, some cannot. One such object is asteroid (162173) Ryugu,
Japanese researchers discover salt crystals in Ryugu asteroid samples
Japanese researchers have identified sodium carbonates, or salt crystals, in samples from the Ryugu asteroid brought back to Earth by the Hay･･･
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.
