Panspermia

(Yes, another mute topic where I post excerpts from articles. This forum is in part an information storage area for bits we need to use in discussions, since we can link to the fuckers directly.)

The Murchison meteorite, which crashed into Australia in 1969, is older than our solar system at 7 billion years. Recent analysis revealed something extraordinary, that all five nucleobases that form DNA and RNA (adenine, guanine, thymine, cytosine, and uracil) were present in this ancient stone. These molecules, confirmed as extraterrestrial in origin, fundamentally challenge the assumption that life's ingredients formed exclusively on Earth.

Radio telescopes have detected more than 100 organic molecules in interstellar dust clouds, including amino acids and nucleic acid components. These findings strengthen the panspermia hypothesis, the idea that life's building blocks are distributed throughout space, potentially seeding planets across the galaxy.
