... Uncovering the Chemistry of Earth-like Planets . ... An Earth-like planet, born from the same nebula as its host star, is composed primarily of silicate rocks and an iron-nickel metal core, and depleted in volatile content in a systematic manner. The more volatile (easier to vaporize or dissociate into gas form) an element is in an Earth-like planet, the more depleted the element is compared to its host star. ... Apr . ...

How to Make Some Critters Evolutionary Advantage Drives Everything! Step 1: Rapid chemical synthesis of raw materials in the atmosphere produces amino acids: NH 3 + 2CH 4 + 2H 2 0 + energy = C 2 H 5 O 2 N + 5H 2 5H 2 CO = Ribose(food) 5HCN+UV +NH 3 = Adenine(anotheraminoacid) Step 2: Monomers loosely mixed in early oceans and shielded from UV Step 3: Local Evaporation, monomers concentrated in clays whose silicate surfaces act as a catalyst Step 4: L ...
