Life found on Ryugu asteroid sample

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,
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.
A sample from Ryugu asteroid is teeming with life — but it’s not aliens
Last year, a study reported the discovery of organic molecules on asteroid Ryugu, sparking discussions about the origins of life and the possibility of panspermia — the idea that life could be seeded across celestial bodies.
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
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 colonised by microbes after atmospheric exposure
Discovery published in Meteoritics & Planetary Science highlights challenge of contamination in space exploration
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.
Rare Asteroid Sample Contaminated by Microorganisms Despite Scientists’ Best Efforts
A chunk of rock collected from the asteroid Ryugu contains bacteria—but, unfortunately, it's not evidence of alien life.
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･･･
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 ...
Japan Researchers Find Salt Crystals on Ryugu Asteroid
