Interstellar cloud conditions make the basic building blocks of life possible
Scientists led by scientist Dr. Danna Kasim have discovered the origin of the building blocks of life
Origins of the Building Blocks of Life: South West Dr. Danna Research Institute Scientist Qasim (Dr Danna Qasim) A new study by indicates that interstellar clouds may have played an important role in manufacturing the building blocks of life in the solar system. Interstellar cloud refers to clouds where there is an accumulation of gas, plasma and dust.
According to Science Daily, Kasim said that some of the oldest objects in the universe, asteroid There are, for example, “Carbon Chondrites” which have contributed to the formation of life. They contain many different molecules and organic substances, including amines and amino acids, which are the main building blocks of life. They are also the essential substances for the production of proteins and muscle tissue.
Most of the meteorite pieces were shattered long ago in the asteroid belt between Mars and Jupiter. Millions of years before the collision with Earth, it orbited the Sun. Responding to how amino acids would have been found in carbonaceous chondrites in the first place, Qasim said most meteorites come from asteroids. Scientists have attempted to regenerate the amino acid by acting on steroidal conditions in the laboratory, a process called “aqueous transformation”. There is no direct evidence for amino acids in interstellar clouds, but there is evidence for amines. The Interstellar Molecular Cloud can provide amino acids. Kasim then simulated the formation of amino acids as they occur in an interstellar molecular cloud.
Working at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, between 2020 and 2022, Qasim explained, “I created ice which is very common in clouds and broke it down to study the effect of cosmic rays. After that, they created an organic residue. Qasim then processed the residue to recreate the asteroid’s state through aqueous transformation and studied the substance, after which he searched for amines and amino acids.
The diversity of amines and amino acids remained constant from the interstellar ice experiments in this research, telling us that the state of the interstellar cloud is flexible enough for asteroids. These conditions can affect the distribution of amino acids found in meteorites. The steroid alone doubled its abundance from the amino acid, suggesting that the steroid affects the amount of amino acid.
Qasim is engaged in studying asteroid samples from missions such as OSIRIS-REx. “When scientists study these samples, they’re usually trying to figure out what asteroid processes are affecting them. Now we need to find out what the building blocks of interstellar cloud life are,” Kassim said.
