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.

An article published in the journal “Earth and Planetary Science Letters” describes a study of the first samples taken in the lower layers of Mount Sharp on Mars by NASA’s Mars Rover Curiosity. A team of scientists in the ARES Division at NASA’s Johnson Space Center compared the minerals found in the first samples analyzed, which show the different environmental conditions that existed over time.

ESA has released new images of a crater with a diameter of about 70 kilometers in the region of the planet Mars called Margaritifer Terra. This is a composite of two images captured by the Mars Express Space space probe’s High Resolution Stereo Camera (HRSC) instrument almost exactly 10 years away in March 2007 and February 2017. The crater and the surrounding area show yet again evidence of the presence of liquid water in Mars’ distant past.

An article published in “The Astrophysical Journal” describes a research about the Boomerang Nebula, described as the coldest spot in the universe. A team led by Raghvendra Sahai of NASA’s Jet Propulsion Laboratory used the ALMA radio telescope to understand why the outflow of materials from the star at the center of the nebula is expanding very quickly. According to the astronomers there’s a companion and the gravitational interactions between the two stars accelerated that outflow.
