Nas sung in Patience (Sabali) that the Earth was born amid a lightning storm. Scientists believe lightning may have created life on Earth. New research suggests that Sun outbursts created life.
Scientists explain amino acid formation to comprehend life. Amino acids make proteins and all biological life.
According to Scientific American, Charles Darwin hesitated to publish his theories on life’s genesis. He exclusively wrote to his friend and colleague Joseph Hooker about his views.
“But if (& oh what a big if) we could conceive in some warm little pond with all sorts of ammonia & phosphoric salts,—light, heat, electricity &c present, that a protein compound was chemically formed, ready to undergo still more complex changes, at the present day such matter would be instantly devoured, or absorbed, which would not have been the case before living creatures were formed,” Darwin wrote in the 1871 letter.
Since then, experts have proposed that lightning or volcanic pools created life. A Life research suggests that solar particles interacting with Earth’s early atmosphere can generate amino acids and carboxylic acids, the building blocks of proteins and organic life.
Life’s long and winding origin.
The 1953 Miller-Urey experiment advanced life’s origins research. Stanley Miller of the University of Chicago attempted to reproduce primeval Earth in the lab. He simulated lightning by repeatedly sparking methane, ammonia, water, and molecular hydrogen in a laboratory.
The Earth’s early atmosphere was considered to include those gases. Miller’s graduate adviser Harold urey discovered 20 amino acids in the chamber a week after it was closed.
That was shocking. Vladimir Airapetian, the co-author of the Life study, claimed in a press statement that the Miller-Urey experiment can synthesise complex organic compounds from early Earth’s atmosphere. NASA’s Goddard Space Flight Center in Maryland employs Airapetian as a star astrophysicist.
The 70 years after the experiment have clouded its conclusions. NASA currently believes ammonia (NH3) and methane (CH4) were scarce during Earth’s early period. Instead, carbon dioxide and molecular nitrogen were added, which need more energy to break down.
searching for alternate energy sources to break down such molecules. Some suggested UV rays or meteor shockwaves. Airapetian and colleagues examined energy particles from the Sun using Kepler mission data.

Airapetian’s 2016 Nature Geoscience study suggested that our planet’s first 100 million years saw near-constant “solar superflares” and a 30% dimmer Sun. Solar superflares are rare solar outbursts. The study suggests it happens every three to ten days when Earth was younger.
Airapetian claimed the Japanese team from Yokohama National University approached him after he released the study.
NASA said that Yokohama National University chemistry professor Kobayashi was studying how galactic cosmic radiation influenced Early Earth’s atmosphere.
Galactic cosmic rays need particle accelerators, thus most researchers ignore them. Kobayashi stated in a news release that he had access to numerous near our facilities. Kobayashi spent over 30 years investigating prebiotic chemistry, and modest changes to his experimental setup allowed scientists test new hypotheses.
Airapetian, Kobayashi, and others performed a Miller-Urey-like experiment. They mixed carbon dioxide, molecular nitrogen, water, and varying amounts of methane. To replicate solar particles, they blasted protons into the mixture. They used spark discharges to reproduce the Miller-Urey experiment.
As long as methane was over 5%, protons produced amino acids and carboxylic acids. Spark discharges, which simulated lightning, needed 15% methane to create amino acids. Lightning produces amino acids a million times slower than protons, even at 15% methane.
Protons (solar particles) created amino acids and carboxylic acids in combinations with methane exceeding 0.5%. Before amino acids produced, spark discharges (lightning) needed roughly 15% methane.
“Even at 15% methane, lightning produces amino acids a million times slower than protons,” Airapetian said.
Solar particles are more efficient than lightning, according to studies. Airapetian claims solar superflares dominate. Thunderclouds from rising warm air produce lightning. This was implausible when the Sun was 30% dimmer.
