An article published in "The Astrophysical Journal" reports a study of 17 molecular clouds in the Small Magellanic Cloud, one of the Milky Way's satellite dwarf galaxies. A team of researchers examined high-resolution images captured using the ALMA radio telescope to obtain information on their characteristics. The examination showed that 40% of those clouds had a more diffused gas, with fluffy structures.

This is a very neat result: using ALMA, a team surveyed 39 massive cosmic clouds, or "star nurseries”… and found in the order of ~800 stellar seeds… and 99% of them lacked the mass to give birth to massive stars. It seems that core density might be more critical than mass for high-mass star formation than previously thought.
