The Sun during a solar flare (Image NASA/NOAA)

NASA released an image of the solar flare occurred on January 21 captured by the GOES-16 satellite that the agency runs with NOAA using the Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) instrument. It’s specifically aimed to observe the Sun and monitor phenomena such as solar storms, which can have consequences on the activity of satellites but also of power plants and other human activities.

An article published in the journal “Nature Geoscience” describes an analysis of data collected during the first year of NASA’s SMAP satellite’s mission. The results were surprising, especially because the data about the soil’s upper layer has a kind of memory of weather, more than you might think from theoretical models or from incomplete surveys carried out prior to this mission.

An article published in “The Astronomical Journal” describes a research on the surface of the dwarf planet Ceres. Using infrared observations carried out with the SOFIA observatory a team of scientists of the Laboratoire d’Astrophysique de Marseille, SETI and NASA’s JPL identified the presence of pyroxene, clay and carbonates that so far deceived the researchers, who thought the surface was rich in carbon compounds.

The big Mimas' mountain seen by the Cassini space probe

NASA has published a new photo taken by the Cassini space probe of Mimas, one of Saturn’s moons, which provides an excellent perspective view of the mountain in the center of Herschel crater, which is not huge in absolute terms but has a diameter which is almost a third of that of Mimas. The mountain is high even by Earth standards with at least 6 kilometers (4 miles) above the crater’s floor and stands out even more on the small moon.

At the American Astronomical Society meeting the results of the study of galaxies NGC 1448 and IC 3639 were presented showing how they led to the identification of supermassive black holes at their centers. A team of researchers used NASA’s NuSTAR Space Telescope to detect the high energy X-ray emission from them and see beyond the dust and gas that hid those areas.
