“Our study was motivated by a fundamental question: how did star formation occur in the early universe?”

"Recent observations of our own Milky Way have increasingly highlighted the importance of filamentary molecular clouds as the primary sites of star formation."

Tokuda and the other scientists wanted to understand if filaments, or threadlike fibers, form during star formation, as this reveals key details about their density and overall composition.

In the paper the researchers concluded that “even if filaments form during star formation, their steep structures may become less prominent and transit to a lower-temperature state.”

Even though prior observation of the Milky Way showed these filaments were present in molecular clouds which became sites for star formation, Alma’s SMC studies demonstrate that stars can also form in fluffier conditions.
