To test the theory, the researchers simulated the energy of an asteroid impact on Earth using the
Prague Asterix Laser System, a powerful laser that can generate around a billion kilowatts of energy at its peak, the Associated Press reported. The laser was directed for a fraction of a second at plasma containing
formamide, a substance scientists believe was likely around on ancient Earth.
What happened next? The laser produced a shockwave in the plasma, generating radiation and temperatures of over 7,600 degrees Fahrenheit. This triggered a cascade of chemical reactions, leading to the formation of four RNA nucleobases: adenine, guanine, cytosine, and uracil.
