Recent research into the possibility of there being life in the Solar System other than on the Earth has suggested that Jupiter may be a good candidate. The reactions within its atmosphere, both photolytic and electrical, lead to the formation of many nitrile and amino compounds. We have simulated electrical discharges in the Jovian atmosphere, using anhydrous methane-ammonia mixtures, and shown the formation of simple aliphatic nitriles, amino-nitriles, and their oligomers. Including hydrogen… 

The role of sulphur in chemical evolution

In the primitive soup, the thiols and sulphides formed in the gaseous phase may have evolved, giving rise to various prebiotic syntheses, including iminothioesters, which can be considered as the immediate precursors of thioesters.

Brown Dwarf Atmospheres as the Potentially Most Detectable and Abundant Sites for Life

We show that the total habitable volume in the atmospheres of cool brown dwarfs with effective temperatures of ∼250–350 K is possibly larger by 2 orders of magnitude than that of Earth-like planets.

The role of chirality in the theories that determine the origin of life are reemphasized—in particular the fact that almost all amino acids utilized in living systems are of thel type, and it is conceivable that the earth provided too hot a location for the production ofl amino acids.

Chemical evolution and the origin of life

Replicating molecules on primordial earth, suggesting chemical evolution on Jupiter via demonstrable alpha-aminonitriles synthesis through demonstrablealpha-amin on Jupiter synthesis is suggested.



Synthesis of Cystine in Simulated Primitive Conditions

IN an attempt to utilize the very abundant long wavelength ultraviolet solar radiation for prebiological organic chemistry, a series of experiments was performed in which H2S was introduced as the

Heterocyclic Compounds indigenous to the Murchison Meteorite

A search for heterocyclic compounds using a sample of the Murchison meteorite, a type II carbonaceous chondrite, found 4-hydroxypyrimidine and two of its methyl substituted isomers but did not find any purines or triazines.
