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.
