If we can understand the chemical complexity of these ices in the molecular cloud, and how they evolve during the formation of a star and its planets, then we can assess whether the building blocks of life should exist in every star system," said Melissa McClure of the Universiteit van Amsterdam, the principal investigator on a research project to investigate cosmic ices.

Their intense light has been burning a hole in the dark fog of the Orion Molecular Cloud for tens of thousands of years.
It's also the brightest portion of a giant molecular cloud (GMC) located approximately 6,000 light-years away in the Sagittarius spiral arm.
Using the L1641 molecular cloud that is part of the Orion A complex, the team showed that the mass distributions of the forming stars, which will become the IMF of that stellar population, are similar yet distinct for stars forming in the field (outside of the filaments) and on the filaments, with the former peaking at smaller mass values than the latter.
The stars associated with variable nebulae are often situated just inside the edge of a dense molecular cloud through which one of the outflows has punched a conical cavity.
A new study, based on radio observation of the Perseus Molecular Cloud, suggests an answer: all sun-like stars are born with a twin, and the binary system either shrinks or breaks apart - as in the case of the sun - within a million years after being born.
The Lupus Molecular Cloud Complex, one of the nearest and largest low-mass star forming complexes, divides into four subgroups, cataloged as Lupus 1-4.
A protostar is a large mass that forms by contraction out of the gas of a giant molecular cloud in the interstellar medium.
Emeritus Professor of Astronomy at Yale, Richard Larson's original paper still inspires new advances in the understanding of molecular cloud structure formation and star formation.
With only a moderately deep accumulated exposure of a few hours, the area surrounding the emission nebulae will start to reveal both the deep ERE and brownish hues of dense molecular cloud.
The cloud of leftover gas and dust or molecular cloud that envelops the new stars is often blown away by their strong stellar winds, weakening the gravitational shackles that bind them.
