ESA has published a new picture of the network of interstellar filaments seen by the Herschel Space Observatory in the space around Polaris, the North Star, which is actually a multiple system. For this reason also known as Polaris Flare, it’s an interstellar cloud in which filaments formed in which there are gas and dust visible especially at infrareds.
An article published in the journal “Icarus” describes new evidence of ancient hydrothermal activity presence in the Auki Crater on Mars. A team of scientists led by Filippo Giacomo Carrozzo of INAF-IAPS, Rome, Italy, used images and spectroscopic data collected by NASA’s Mars Reconnaissance Orbiter (MRO) space probe to identify geological structures and mineral hydrates that confirm that hypothesis.
An article published in the journal “Physical Review Letters” describes a research on Sagittarius A*, the supermassive black hole at the center of the Milky Way. A team of scientists from the University of Princeton and the US Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) developed a new method to create a model of the accretion disk which feeds Sagittarius A*.
