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.

Earth Microbes Discovered in Asteroid Ryugu Sample, Raises Contamination Concerns
A study has confirmed that terrestrial microbes colonised a Ryugu asteroid sample after its return to Earth in 2020. The micro-organisms were found to proliferate upon exposure to Earth's atmosphere, raising concerns over contamination risks in planetary exploration. Published in Meteoritics & Planetary Science, the findings underline the need for ...

Phosphorus Grains in Ryugu Samples Offer Insights into Earth’s Early Life Chemistry
Scientists have discovered phosphorus-rich grains in samples from the asteroid Ryugu, brought back by Japan’s Hayabusa2 mission. These grains, thought to have come from the outer Solar System, may have interacted with early Earth’s water, releasing essential nutrients like phosphorus and nitrogen. This interaction could have played a role in th...

Asteroid Discovery Suggests Ingredients for Life on Earth Came From Space
Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago. Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Sp...

Water Drop Discovered on Ryugu Asteroid Offers Clues to Origins of Life on Earth
A water drop discovered on specks of dust from Ryugu, an asteroid close to Earth, has offered new support for the theory that life on the planet was seeded from outer space. The sample of the asteroid retrieved by the Hayabusa-2 probe has already showed that some of the building blocks of life on Earth, amino acids, may have been formed in space. T...

Asteroid Ryugu Sample Has Dust Grains Older Than Our Solar System
Examining samples from asteroid Ryugu, scientists have made a startling discovery. They have spotted microscopic grains of ancient materials that are even older than our Solar System. Located in the near-Earth solar orbit, asteroid Ryugu is shaped like a spinning top and orbits the Sun every 16 months.

Water Arrived On Earth From Asteroids, Claims Study
scientists have said that water might have arrived on our planet by asteroids from the outer edges of the solar system.

Asteroids From Outer Edges of Solar System May Have Brought Water to Earth, Suggests New Study
Asteroids from the outer edges of the solar system may have brought water to Earth, claim scientists after analysing rare samples collected on a six-year Japanese space mission Hayabusa-2. The researchers are scrutinising material brought back to earth in 2020 from the asteroid Ryugu.

Ryugu Samples Are Most Contaminant-Free Outer Solar System Particles, Says Study
In an in-depth analysis conducted by a team of Japanese researchers at JAMSTEC (Japan Agency for Marine-Earth Science and Technology), it is found that the Ryugu samples brought on Earth in December 2020 by the Japanese aircraft Hayabusa-2 are the most “uncontaminated” samples. This will help scientists get a crystal-clear insight into the chem...

Asteroids Appear Rough Due to Space Dust Hopping on Them, Suggests Research
A new study from physicists suggests that tiny grains of space dust may hop around on the surface of asteroids, making them appear rough. The study, published in the journal Nature Astronomy, may help scientists understand how asteroids bring them dangerously close to Earth.

Building Blocks of Life Discovered on Asteroid Located 200 Million Miles Away From Earth
Scientists studied materials taken from the asteroid by the Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 probe, which landed on Ryugu in 2018. The spacecraft retrieved 0.2 ounces (5.4 grams) of material from the asteroid's surface and subsurface in 2019, stored it in an airtight container, and returned it to Earth.

Japan's Hayabusa2 Space Probe on Its Way Back After Ryugu Asteroid Mission
The unmanned Hayabusa2, named after a falcon, began leaving Ryugu last week, but it is still sending images back to Earth.
