NASA has published some photos taken by its New Horizons space probe’s LORRI instrument in December 2017. During the course of its journey that will lead to the object called 2014 MU69’s flyby, New Horizons took photos that beat the record that belonged to Voyager 1 for the farthest photo ever taken from Earth capturing images of the open stellar cluster called Wishing Well and two Kuiper Belt Objects called 2012 HZ84 and 2012 HE85.

An article published in the journal “Science” describes the discovery of eight areas on the planet Mars where soil erosion revealed the presence of large glaciers. A team of researchers located and studied the areas thanks to NASA’s Mars Reconnaissance Orbiter (MRO) space probe’s High Resolution Imaging Science Experiment (HiRISE) camera. The slopes generated by erosion offer new information on those glaciers’ stratified structure and consequently on the red planet’s climate history.

At the annual American Geophysical Union meeting, NASA scientists presented the results of the latest research on bright spots on the dwarf planet Ceres. In particular, the activity detected over time, especially by NASA’s Dawn space probe with variations in their brightness confirm the possibility that on Ceres there’s still a geological activity that is modifying this dwarf planet’s surface.

Yesterday at the annual American Geophysical Union meeting the new discoveries concerning Jupiter’s Great Red Spot of Jupiter and a new ​​radiation area were announced. The data collected by NASA’s space probe Juno during a flyby on July 11, 2017 allowed to discover something new about that storm bigger than Earth, for example finding an answer to one of the crucial questions about it establishing that it’s about 300 kilometers (200 miles) deep.

ESA has released images captured by its Mars Express space probe that show the Mars area called Sirenum Fossae. The High Resolution Camera Stereo Camera (HRSC) camera allowed to take photos of an area whose appearance was determined by an ancient volcanic activity, with the result that a system of tectonic faults called graben in jargon stretched for thousands of kilometers on the red planet’s surface.
