Understanding how stars form from gas clouds is no simple task. A large cloud of molecular gas begins to collapse in the interstellar medium. From this collapse, gravity begins to play an important role. Also, with increasing density, a star eventually forms at its center that begins to transform hydrogen atoms into helium atoms.
As scientists begin to look in detail at the physical processes behind this transformation, it becomes increasingly clear that it is a turbulent process. For example, a gas cloud does not form just one star, but several stars at different times. And the first stars to be born begin to radiate energy and dissolve the cloud that is a stellar nursery. Understanding the consequences of the birth of these first stars is still an open question. Do these newborn stars hinder the birth of other generations or not?
Fortunately, we have an excellent field to study star forming areas: the Tarantula Nebula, also known as the Dorados 30 region. This nebula is located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. This nebula is one of the densest star forming regions we know of and is close enough to be analyzed in detail. In addition, the Dorados 30 region is home to the most massive stars we know.

A recent study using ESO’s (European Southern Observatory) ALMA telescope has shown in detail what happens to the gas cloud when the first stars begin to appear. Contrary to expectations, the first stars do not prevent the formation process in the cloud from continuing. The gas cloud begins to disperse and form filaments, and star formation continues on these filaments.
To perform this work, the team of scientists used the ALMA telescope to map the element carbon monoxide through observations in the radio range. This element is the second most abundant element in gas clouds and can help map where the cloud is still cold and collapses to form new stars. In the pictures below we can see the location and shape of the cold gas filaments in the nebula.
