Beaming Pyrimidines Part 4

The Photochemistry of Pyrimidine in Realistic Astrophysical Ices and the Production of Nucleobases SUMMARY: To mimic the conditions on comets or space clouds, the gas mixture beamed in this experiment was a mixture of: water, methanol, ammonia, methane, and pyrazine. Pyrazine is an isomer of pyrimidine (both have the chemical formula C4H4N2). This gas mixture… Continue reading Beaming Pyrimidines Part 4

Beaming Pyrimidines Part 3

Irradiation of Pyrimidine in Pure H2O Ice with High-Energy Ultraviolet Photons SUMMARY: In Part 3 of pyrimidine beaming, researchers looked at different energy levels of photons and their effect on pyrimidines. They beamed a water and pyrimidine ice mixture with photons of three different wavelengths. Uracil and the molecule that is the precursor to uracil… Continue reading Beaming Pyrimidines Part 3

Beaming Pyrimidines Part 2

Thymine and Other Prebiotic Molecules Produced from the Ultraviolet Photo-Irradiation of Pyrimidine in Simple Astrophysical Ice Analogs(NOT OPEN ACCESS) SUMMARY: In the second edition of beaming pyrimidines, instead of using ammonia, scientists beamed pyrimidines with methanol, water and methanol, methane, and water and methane. As with “Beaming Pyrimidines Part 1”, the gases were cooled way… Continue reading Beaming Pyrimidines Part 2
