An article published in the journal “Nature” describes a study of the galaxy MACS 2129-1. An international team of researchers led by Sune Toft of the Niels Bohr Institute (NBI), University of Copenhagen, Denmark used the Hubble Space Telescope and ESO’s Very Large Telescope (VLT) to gather information about MACS 2129-1. The result is that no new stars are being formed and this is really surprising because it’s very far away so we see it as it was at a time when the universe was at the highest rate of star production.

An article published in the “Astrophysical Journal” describes a research on a star formation phenomenon in the Orion Molecular Cloud 2. A team of Astronomers led by Mayra Osorio of the Astrophysical Institute of Andalucia (IAA-CSIC) in Spain used the VLA radio telescope to find the evidence that a jet of material ejected by a young star might have triggered the formation of another younger protostar.
At a press conference, NASA presented the new catalog of exoplanet candidates produced thanks to the observations of its Kepler space telescope. Exoplanet candidates are a total of 4,034 of which 2,335 have been confirmed as actually existing. There are 219 new candidates, of which 10 might be similar to Earth and at the same time be in their solar system’s habitable zone.
An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a study on the diffusion of binary systems composed of low-mass stars. The astronomers Sarah Sadavoy of the Smithsonian Astrophysical Observatory and Steven Stahler of the University of Berkeley studied very young stars in the molecular cloud of the constellation of Perseus concluding that that kind of stars is always born in pairs, including the Sun.
An article published in the journal “Nature Astronomy” describes a study of the massive newborn baby star Orion KL Source I. A team of astronomers led by Tomoya Hirota used the ALMA radio telescope to capture what was called the birth cry of that star and determine that its outflow’s motion and shape indicate that the interaction of centrifugal and magnetic forces in a disk surrounding the star plays a crucial role in that cry.
