A team of astrophysicists and computational astronomers have discovered why sibling stars look alike – those formed from a single cloud share the same chemical fingerprint due to early, fast and turbulent mixing of gas in the giant molecular clouds where star formation occurs.

Current theories suggest that rocky planets like Earth start their lives as microscopic bits of dust tinier than a grain of sand. However, astronomers have recently discovered that filaments of star-forming gas near the Orion Nebula might be full of pebble-sized particles.

Berkeley Lab and University of Hawaii research outlines the story of soot, with implications for cleaner-burning fuels.

Organic Conundrum In Milky Way’s Satellite Galaxy, The Large Magellanic Cloud
2014-06-23 03:03:26

A group of organic chemicals that are considered carcinogens and pollutants today on Earth, but are also thought to be the building blocks for the origins of life, may hold clues to how carbon-rich chemicals created in stars are processed and recycled in space.

Planetary Nebulae Observed Releasing Water-Building Molecules

Molecular Cloud -- Molecular clouds are interstellar nebulae that have a density and size sufficient to permit the formation of H2, molecular hydrogen. However, this molecule is difficult to detect, and the molecule most used to trace the H2 is CO (carbon monoxide). The ratio between CO luminosity and H2 mass is roughly constant, although there are reasons to doubt this assumption in observations of some other galaxies. In the Milky Way, molecular clouds account for roughly one-half...

Interstellar Cloud -- Interstellar cloud is the generic name given to accumulations of gas and dust in our galaxy. Depending on the density, size and temperature of a given cloud, the hydrogen in it can be neutral (HI clouds) or molecular (molecular clouds). Chemical compositions Analysing the composition of interstellar clouds is achieved by studying electromagnetic radiation that we receive from them. Large radio telescopes scan the intensity in the sky of particular frequencies of...
