A graphic illustrating the Galactic distribution of phosphorus in the range 0–25 kpc from the Galactic Centre, as identified from stellar and interstellar observations. Detections by atomic transitions in stellar photospheres are denoted by green stars (from ref. 2 and references therein), in diffuse clouds by purple circles (ref. 16 and those therein17,18,19), and in planetary nebulae by blue triangles, while magenta circles and cyan diamonds mark the identifications in molecular clouds and circumstellar envelopes from molecular lines. The red square shows the position of WB89-621. The orange X indicates the solar system. The APOGEE survey detections are not shown per possible contamination. WB89-621 is the only known source of phosphorus in any form beyond 12 kpc.

Phosphorous Has Been Discovered In The Outer Reaches Of The Milky Way

by Keith CowingNovember 16, 2023November 16, 2023

Despite its importance in planet formation and biology, phosphorus has been identified only in the inner 12 kpc of the Galaxy2-19. The study of this element has been hindered in […]

Developing Future Space Experiment Platforms For Astrobiology And Astrochemistry

by Keith CowingJune 30, 2023June 30, 2023

Space experiments are a technically challenging but a scientifically important part of astrobiology and astrochemistry research. The International Space Station (ISS) is an excellent example of a highly successful and […]
