The Hubble Space Telescope was used to create new maps of the planet Jupiter. Hubble’s Wide Field Camera 3 captured a series of images of the planet within the Outer Planet Atmospheres Legacy program. The aim is to produce new maps every year and in the case of Jupiter 10 hours of daily shooting made it possible to discover new phenomena including changes in the Great Red Spot.
A new study carried out by the team that runs the Mars Rover Curiosity confirmed that between 3.8 and 3.3 billion years ago there were lakes in what is now Gale Crater. At its center today there’s Mount Sharp, which foundations were formed by sediments deposited layer upon layer over a very long period. The results of this study were just published in the journal “Science”.
NASA published the first color photos that show the atmosphere of the dwarf planet Pluto taken by the New Horizons space probe during its July 14, 2015 flyby. The previous images showed the haze in the atmosphere but not its colors so with the arrival of the new ones it was a surprise to find that Pluto’s sky is blue. Another discovery concerns the regions of water ice detected on the surface of the dwarf planet.
The mysteries of the dwarf planet Ceres are a topic of discussion at the European Planetary Science Congress going on these days in Nantes, France. For the occasion, NASA published new topographic maps of Ceres based on data collected by its Dawn space probe, which has been mapping it for a few weeks. The latest news on this dwarf planet came from some emission of energetic electrons.
Yesterday NASA announced the existence of flows of liquid water on Mars. The study, just published in the journal “Nature Geoscience”, is based upon years of analysis of data collected mainly thanks to the NASA’s MRO (Mars Reconnaissance Orbiter) space probe. The images captured by its camera and spectrometric data allowed to find streams of water along the walls of craters and slopes that vary over time and perchlorate salts in them.
