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.
An article published in the journal “Nature Geoscience” describes a research in which a team of researchers argues that the signs of liquid water flows found on Mars are actually made up of dry sand. The possible existence of what are technically called RSLs (recurring slope lineae), streaks of sand washed by liquid water, was announced in September 2015 by NASA. A new study of data collected by NASA’s MRO (Mars Reconnaissance Orbiter) space probe may, however, show a different situation.
An article published in the journal “Nature” describes a research on the haze present in the atmosphere of the dwarf planet Pluto’s and its effects on its temperatures. According to a team led by Xi Zhang of the University of California at Santa Cruz, the haze absorb the already low heat from sunlight and emits infrared radiation cooling the atmosphere. That’s the explanation for the fact that NASA’s New Horizons space probe measured a temperature even lower than expected.
