NASA released new photos of various craters on the dwarf planet Ceres taken from its Dawn space probe, currently in its lowest orbit at an altitude of 385 kilometers (240 miles). From there, Dawn is making the most detailed mapping of Ceres and is providing really interesting details of craters that had already attracted the attention of scientists such as Haulani and Oxo.
A photograph taken by the Cassini space probe shows a huge system of fractures that have a shape similar to a letter Y on the surface of Enceladus, Saturn’s moon become in recent years one of the most interesting objects of astronomical studies. Called “Y-shaped discontinuities”, these elements of Enceladus’ icy surface are probably relatively young revealing the existing geological activity on this moon.
An article published in the journal “Astronomy & Astrophysics” describes a study of the brown dwarfs that should be present in the cosmic neighborhood. A team of astronomers from the Leibniz-Institut für Astrophysik Potsdam (AIP), Germany, re-analyzed data from observations and cataloging of the brown dwarfs less than six and a half parsecs from Earth and concluded that there should be more of them and maybe we haven’t found them yet.
A little while ago the operations to connect the BEAM expandable module to the International Space Station were completed. The operation lasted about four hours during which the Canadarm2 robotic arm was used to transport BEAM from the unpressurized section of the Dragon spacecraft to the Tranquillity module. At that point, it was berthed to the Station via remote control, just like they do with the cargo spacecraft. This is only the first phase of its installation, which will proceed slowly, step by step.
An article published in the journal “Science” describes the analysis of the composition of interstellar dust that entered the solar system and was intercepted by the Cassini space probe. Among the instruments on board there’s the Cosmic Dust Analyser (CDA), which over the years of its mission has collected millions of dust samples: 36 of them were found to be of interstellar origin.
