Interstellar Formamide (NH2CHO), A Key Prebiotic Precursor
Formamide (NH2CHO) has been identified as a potential precursor of a wide variety of organic compounds essential to life, and many biochemical studies propose it likely played a crucial role […]
Obtaining a History of the Flux of Cosmic Rays using In Situ Cosmogenic 14C Trapped in Polar Ice
Carbon-14 (14C) is produced in the atmosphere when neutrons from cosmic-ray air showers are captured by 14N nuclei. Atmospheric 14C becomes trapped in air bubbles in polar ice as compacted […]
Astrochemistry: Discoveries to Inform the Chemical Sciences and Engineering Communities = Proceedings of a Workshop-in Brief
Throughout much of human history, space was thought to be a void in which only ions or radicals existed. It was only in the last half of the 20th century […]
Simulations Of Ice Chemistry In Cometary Nuclei
The first computational model of solid-phase chemistry in cometary nuclear ices is presented. An astrochemical kinetics model, MAGICKAL, is adapted to trace the chemical evolution in multiple layers of cometary […]
Study Reveals 'Radical' Wrinkle in Forming Complex Carbon Molecules in Space
A team of scientists has discovered a new possible pathway toward forming carbon structures in space using a specialized chemical exploration technique at the Department of Energy’s Lawrence Berkeley National […]
Survey Observation of CH3NH2 and Its Formation Process
We present the observational result of a glycine precursor, methylamine (CH3NH2), together with methanol (CH3OH) and methanimine (CH2NH) towards high-mass star-forming regions, NGC6334I, G10.47+0.03, G31.41+0.3, and W51~e1/e2 using ALMA. The […]
Interstellar Iron Found In Antarctic Snow
The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team with significant […]
Key Phosphorus-based Molecule For Life On Earth May Have Come From Space
The answer to “How did the first organisms on Earth incorporate the critical element phosphorus?” has been a quandary for researchers, but, University of Hawaiʻi at Mānoa physical chemists believe […]
Volatile Species In Comet 67P/Churyumov-Gerasimenko: Investigating Link From The ISM To The Terrestrial Planets
Comets contain abundant amounts of organic and inorganic species. Many of the volatile molecules in comets have also been observed in the interstellar medium and some of them even with […]
