When stars are born, they do it inside a molecular cloud. Astronomers long assumed that the “crèche” supplied all the nutrients that protostars needed to form. However, it turns out they get help from outside the nest.
A new study published in the journal Astronomy & Astrophysics by scientists at the Max Planck Institute for Extraterrestrial Physics delved into the role of streamers and filaments in the star-birth process. Think of them as channels that extend out from the interior of the stellar creche, sometimes out as far as 10,000 astronomical units (about 0.15 light-years)...
