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… Expand
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. Expand
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 $\sim 250$-$350$ K is possibly larger by two orders of magnitude than that of Earth-likeExpand

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. Expand
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. Expand


Jupiter: Chemical composition, structure, and origin of a giant planet
Abstract A comprehensive analysis is made of the observational and theoretical information regarding the composition, structure, and origin of Jupiter, viewed as a cosmogonic test case of a giantExpand
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 theExpand
The physical properties of the Jovian atmosphere inferred from eclipses of the Galilean satellites. I. Preliminary results
Abstract Simultaneous two-color photometry of Ganymede was carried out at blue (γ 4500 A) and yellow (γ 5790 A) wavelengths during its eclipse by Jupiter on 1970 March 24. In both colors, the shapeExpand
Organic synthesis in a simulated Jovian atmosphere
Abstract Reactions which may occur in the Jovian atmosphere were simulated by passing an electrical discharge through a mixture of methane and ammonia. Analysis of the volatile fraction revealed theExpand
High dispersion spectra of the outer planets- i. jupiter in the visual and red
Abstract Our high dispersion spectrograms of Jupiter partially resolve the red methane and ammonia bands and show new, weak lines. At times the Jovian ammonia and methane gases do not co-rotate withExpand
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. Expand
Gas-liquid chromatography of protein amino acids separation factors.
The separation ability of ethylene glycol adipate as a liquid phase was found to be superior to neopentyl glycol sebacate, consistent, and reproducible with respect to time and temperature. Expand
