With further analysis, they also found that the sugars were extraterrestrial in origin, and not the result of contamination here on the Earth.
The discovery adds more weight to the hypothesis a meteor blitz on ancient Earth could have kick-started life by providing the necessary building blocks. The new discovery provides to the growing list of biologically important compounds that were present in meteorites, supporting the speculation that chemical reactions in asteroids-the parent bodies of many meteorites-could make a few of life's components.
Meteorites may have made these initial sugar deliveries to Earth, which include the RNA component ribose and other bio-essential sugars like arabinose and xylose, which are all fundamental and critical biological building blocks.More news: Borderlands 3 First DLC Revealed - Moxxi's Heist Of The Handsome Jackpot
An enduring mystery regarding the origin of life is how biology could have arisen from non-biological chemical processes.
The newly discovered extraterrestrial sugar throws light on the possibility that RNA coordinated life origins before DNA. RNA is perhaps best known as a master messenger, responsible for copying the genetic information stored in DNA and delivering that data to the cellular structures responsible for making the proteins that humans and other organisms need to survive.
The meteorite samples were analyzed by gas chromatography-mass spectrometry.More news: Bigg Boss 13: Sidharth Shukla asks Rashami Desai if she loves him
A team including Yoshihiro Furukawa, an associate professor at Tohoku University, and researchers from the National Aeronautics and Space Administration and other organizations analyzed three kinds of meteorites, including the Murchison meteorite that fell in Australia in 1969. They found that the analyzed space objects contain sugar.
The researchers also conducted a laboratory simulation experiment of a potential sugar formation reaction in space.
Asteroid collision brought life to earth? The discovery that molecules come from space makes it a little more complicated to make sense of how life comes into being and makes the work of researchers hard. Since it's possible that the opposite would work fine - right-handed amino acids and left-handed sugars - scientists want to know where this preference came from.
