At the UK’s Royal Astronomical Society’s National Astronomy Meeting being held in Nottingham new images of the planet Jupiter were presented, obtained with the infrared VISIR instrument installed on ESO’s VLT. They will help better understand Jupiter’s atmosphere on the occasion of the arrival of NASA’s Juno space probe, scheduled for July 4, 2016.

An article published in the journal “Nature” describes a new research on the famous white spots in the dwarf planet Ceres’ Occator Crater. According to a team led by Maria Cristina De Sanctis, INAF – IAPS, the most abundant mineral is sodium carbonate. It’s a surprising result because that’s a salt that on Earth is abundant in hydrothermal sources and this raises the possibility of the presence of liquid water in Ceres underground.
