An article published in “The Astronomical Journal” reports the discovery of areas of remarkable star formation in the molecular clouds known as Digel Clouds, more than 58,000 light-years from the center of the Milky Way. A team of researchers used the James Webb Space Telescope to obtain the detail needed to recognize protostars, outflows and jets of material, and nebular structures. Star formation is more intense than what was visible in observations conducted with other instruments and is interesting also because the Digel Clouds are poor in elements heavier than hydrogen and helium, a characteristic that makes them similar to the primordial Milky Way.

An article published in the journal “Nature” reports the results of a study on some fast radio bursts linked to persistent emissions that associates that long duration with a bubble of plasma that generates that radiation. A team of researchers led by the Italian National Institute for Astrophysics registered and studied the fast radio burst with the weakest persistent emission detected so far, cataloged as FRB20201124A, and two other similar events with the VLA radio telescope collecting data that provide evidence of the presence of the plasma bubble at the origin of the radio emissions.

A new image captured by the James Webb Space Telescope reveals new details of a protostar forming within the molecular cloud cataloged as L1527. The MIRI instrument offered new information on the ongoing processes that are leading to the birth of a new star. An accretion disk is barely visible edge-on and is important because the protostar is still absorbing materials from it and planets could form within it in the future. During its formation, the protostar emits jets of gas that collide with the remains of the surrounding cloud, generating the structures MIRI sees in a color that is blue in the top image (NASA, ESA, CSA, STScI) thanks to the presence of polycyclic aromatic hydrocarbons (PAHs), compounds that are common in space.

An article accepted for publication in “The Astrophysical Journal” reports the first detection of aligned bipolar jets emitted by protostars in the Serpens Nebula. A team of researchers used observations conducted with the James Webb Space Telescope to obtain the details needed to spot these jets. Typically, they have different orientations within a star-forming region but in this case, they are aligned almost perfectly. This suggests that star formation may be at a unique time in its history in the Serpens Nebula and provide crucial information about these processes.

At the 244th Meeting of the American Astronomical Society, a study was presented of what turned out to be a pair of stars inside the WL20 group, cataloged as WL20S. The authors of this study combined observations conducted with the ALMA radio telescope and the James Webb Space Telescope to obtain the information necessary to establish that in that system there are two young stars, and not one as astronomers thought, which formed between 2 and 4 million years ago. Both stars are surrounded by disks of materials in which there could be planets forming and parallel jets of materials emitted by the two stars.
