An article in the journal “Monthly Notices of the Royal Astronomical Society” describes a study of the galaxy SAGE0536AGN and in particular the supermassive black hole at its center, which is 30 times larger than expected. This is the result of measurements conducted by a team of astronomers at Keele University and the University of Central Lancashire, an anomaly all to explain.

After more than two months since the extraordinary Pluto flyby of NASA’s New Horizons space probe some people might think that the data arrived to Earth are enough to know this dwarf planet comprehensively. Reality keeps on being very different on this small world frozen yet as varied as you would expect from a geologically active planet with an atmosphere that can erode its soil. Here then is the image of a “snakeskin” surface that again leaves scientists puzzled and surprised.
An article just published in the journal “Nature” describes a research on the daily water-ice cycle on the surface of the comet 67P/Churyumov-Gerasimenko and its vicinity. A team of scientists led by Maria Cristina De Sanctis from Rome’s IAPS-INAF (National Institute of Astrophysics – Institute for Astrophysics and Space Planetology) analyzed data collected by the ESA’s Rosetta space probe’s VIRTIS spectrometer discovering that in some areas the ice water disappears in the day and reappears in the night.
The Chinese government announced its intent to enter into a new phase of its involvement in the development project of the SKA radio telescope by signing a letter of intent with the SKA Organisation that runs it. Vice Minister Jianlin Cao from the Chinese Ministry of Science and Technology (MOST) signed the letter of intent on behalf of his government. With this act, China the joins nations that are turning the SKA into an intergovernmental organization with a treaty to formalize the relationship between the project and its members.
While in the field of astrophysics are still talking about a pair of supermassive black holes that will clash in the future, a new study suggests that these situations are rarer than expected. A team of astronomers led by David Roberts of Brandeis University analyzed data collected with the VLA (Very Large Array) to examine cases in which possible galaxy mergers the brought supermassive black holes at their centers to form a pair. The conclusion is that in many cases the galaxy merger is only apparent.
