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."
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.
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.
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.
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.
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.
