Yesterday at the Royal Astronomical Society’s National Astronomy Meeting (NAM2015), at the Venue Cymru centre in Llandudno, Wales, evidence were presented of the discovery of supermassive black holes found thanks to the NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) space telescope. An international team led by astronomers at the British Durham University detected the high energy X-ray emission from five black holes that were previously hidden by dust and gas.

A little while ago the Progress M-28M spacecraft docked to the International Space Station. The Russian space cargo ship, launched last Friday, is carrying food and water that ensure a reserve of about another month to the crew as well as scientific experiments, propellant and various hardware. For the nations cooperating in running the Station it’s certainly a relief after three mishaps in less than a year, so much as to be defined Christmas in July.

A few hours ago the Progress M-28M spacecraft blasted off on a Soyuz U rocket from the Baikonur base in Kazakhstan in a resupply mission to the International Space Station also referred to as Progress 60. Less than ten minutes after the launch, the cargo spaceship regularly separated from the rocket’s upper stage, entered a preliminary orbit and deployed its solar panels and navigation antennas. After recent failures in the launches of cargo spaceships, one hopes that this mission may once again be the routine we had become used to.

An article published in the journal “Nature” describes a research on a series of 18 pits on the comet 67P/Churyumov-Gerasimenko. They are nearly circular and some of them are a source of activity, emitting jets of gas and dust. They were discovered a long time ago but an analysis of the images collected by ESA’s space probe Rosetta’s OSIRIS camera allowed to establish that probably they were formed following a collapse of the surface.
