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 snow (firn) transforms into ice.

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 that scientists began to discover the existence of molecules, such as ammonia, in space.

Sorting Out Peptide Mixtures

Scientists supported in part by the NASA Astrobiology Program have developed a new method to analyze mixtures of glycine and glycine oligomers using ion-pair high-performance liquid chromatography (IP-HPLC).

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 Laboratory (Berkeley Lab).

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 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 involvement from the Technical University of Munich (TUM) has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood.

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 a meteoric visitor could be the critical link.

The work is devoted to the adaptation of the results of laboratory studies of the laser-induced dissociation of molecules of benzene adsorbed on a quartz substrate to the conditions of the interstellar medium.

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 similar relative abundances, indicating formation under similar conditions or even sharing a common chemical pathway.

The search for complex organic molecules in the interstellar medium (ISM) has revealed species of ever greater complexity.
