Three studies were published on Tuesday Environmental GeoScience and Natural environment check out the pristine property the Osiris-rex mission collected from a near-Earth asteroid The maid And delivery to the world in 2023
In another study, a group led by Yoshihiro Fukawa of Tohoku University in Japan found six types of sugar, including ribar, in glucose, a critical energy source for living organisms. This is the first time that sugar has been taken from Pristine an asteroid property.
Previously, scientists had discovered Amino acids – The building blocks of proteins – and nucleobases, which help store genetic information. The discovery of sugar ends in a set of essential elements needed to make proteins and genetic material.
“What this means is that these building blocks of life have spread from the outer solar system all the way to the inner solar system,” said Danny Glavin, the astronomer who led the analysis of the natural sample, in a NASA video. “They were everywhere, niquitous, which really makes me very optimistic that maybe these building blocks could provide life on Earth, but it could happen somewhere else – Mars, Europa, the outer solar system.”
A near-Earth asteroid can be a short-term moon, and then there is a risk of crashing
But what the researchers didn’t find could shed more light. Seeing especially in the smoke was DexyrIbose, Sugar used to build DNA. Finding that adds confidence to the so-called “RNA World” hypothesis, which proposes that the first living things relied on RNA alone to carry genetic information and before basic chemical reactions, before proteins and proteins arrived.
“This discovery of Ribose is, in fact, very important,” Glavin said. “Maybe the origin of life was a single RNA artist.”

NASA’s $800 Million Osiris-Rex Mission, short for The origin, visual interpretation, resource identification, and security of Reveloth Explorerlaunched in the year 2016. The robotic spacecraft completed its 2,000-mile journey when it dropped the capsule from 63,000 miles above the Earth in the Utah desert. It is the first US mission to hold a sample of an asteroid.
These are the most precious commemorative bells of SOCE NASA found that Apollo Moon Rocksgathered between 1969 and 1972. The mission succeeded in collecting approx cup-cup of bennu crowh stones and dirt. Although that may not sound like much, scientists are waiting for those discoveries to be made for decades to come.
“What this means is that these building blocks of life … were everywhere, they were creative.”
The second study found an unexpected phenomenon unlike anything seen before space rocks. The contents, now hardened with age, may have had a change in hardness when formed, made of chains like polymers of nitrogen and oxygen. These complex molecules may provide the impetus to synthesize the small organic ingredients necessary for life on earth.
The object was probably formed before Bennu broke up with a large asteroid that existed early in the solar system.
“If we look at its chemical composition, we see the same types of chemical groups that occur in Polyurethane on Earth, which makes this material from Bennu similar to the ‘space of Scord,’ a NASA Astrophysicist who led one of the Natural environment papers.

The third study focused on the so-called “grain plume,” a dust cloud that formed around ancient stars before the birth of the solar system and was later deposited on asteroids and planets. A team led by NASA’s Ann Non Nguyen, a planetary scientist, found that the Bennu sample contained six times more dust than supernovas rather than being measured against any other background material.
That high concentration suggests that Bennu’s parent body was formed in a region chock full of debris from dying stars. However Fluids later changed most of the asteroid’s rockThe investigators also found unaltered packages, saving the living things and the poor food of the captain from water damage.
Scientists say this discovery reinforces the idea that the green ingredients for life were common, widely distributed and brought to Earth by asteroids, helping to lay the foundation for planetary-like biology.
“I’m very optimistic that we can find life outside of Earth, even in our solar system,” Glavin said.
