An article published in the journal “Nature Communications” offers an explanation to the loss of carbon in the planet Mars’ atmosphere. A team of scientists from CalTech (California Institute of Technology) and NASA’s Jet Propulsion Laboratory studied the available data focusing on the problem of carbon because what remained is less than expected even taking into account the recent results on the red planet’s atmosphere loss.

ESA has published images of Valles Marineris on Mars captured by its Mars Express space probe in July 2015. It’s a huge complex of geological fractures much wider and longer than the American Grand Canyon. In particular, scientists focused on the photographs taken by Mars Express’ High Resolution Stereo Camera (HRSC) in an area called Aurorae Chaos, where there are still traces of ancient water flows.

NASA released images of the dwarf planet Pluto and its main moon Charon showing most of their surface. They’re formed by compositions of various photographs taken by two cameras of the New Horizons space probe: the Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera. The photographs were taken between July 7 and 13, during the approach that led to the extraordinary July 14, 2015 flyby.

An article published in the journal “Astrophysical Journal” describes the discovery of the oldest giant galaxies carried out thanks to ESO’s VISTA (Visible and Infrared Survey Telescope for Astronomy) telescope. A team of astronomers led by Karina Caputi of the Kapteyn Astronomical Institute at the University of Groningen, Netherlands, identified galaxies that existed when the universe was between 750 million and 2.1 billion years old. This result is surprising because the birth of galaxies so massive wasn’t expected so soon.

The ALMA radio telescope is currently the world’s most powerful yet in recent months some experiments were carried out that made it even more powerful by working together with other radio telescopes to create a virtual instrument that may have a size similar to that of Earth. This was made possible by combining observations from ALMA with those from other radio telescopes located in other continents.
