In the journal “Nature Communications” an article was published on the study of images of the planet Venus taken during its transit, its passage between the Sun and the Earth, which occurred in June 2012, taken by two satellites: NASA’s SDO and NASA and JAXA’s Hinode. This research allowed to look at Venusian atmosphere in a different way measuring the way it absorbs the different types of light. This type of study allows to get important clues about the presence of various chemical elements in the atmosphere’s layers. It will also be useful to improve the techniques to examine exoplanets’ atmosphere.
An article published in “Nature” describes the research conducted by an international team led by Jochen Greiner of the Max-Planck-Institut für extraterrestrische Physik, Garching, Germany who studied a gamma-ray burst (GRB) detected on December 9, 2011 by NASA’s Swift satellite and called GRB 111209A. It was an exceptional phenomenon because it lasted more than three hours when gamma-ray bursts typically last from a few seconds to a few minutes. It was the first case of GRB associated with a supernova, called SN 2011kl, which produced a magnetar, a neutron star with an incredibly strong magnetic field.
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.
