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.

The Hubble Space Telescope took a picture of the planetary nebula PK 329-02.2, also known as ESO 178-15 or Hen 2-150 and commonly called Menzel 2 (Mz 2) because it was discovered by the astronomer Donald Menzel in 1922. Distant little more 7,700 light years from Earth, it’s visible in the constellation Norma and is another case in which a planetary nebula offers a breathtaking show, in this case with a blue cloud that aligns with the two stars at its center.

In the middle, a 3D shape model used to determine the directions in which the terraces/strata are sloping and to visualise how they extend into the subsurface. On the right, local gravity vectors visualised on the comet shape model perpendicular to the terrace/strata planes (Image ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA; M.

At the European Planetary Science Congress going on these days in Nantes, France, evidence were presented that the strange shape of the nucleus of comet 67P/Churyumov-Gerasimenko is due to the fact that it was born from the merger of two small comets occurred a few billion years ago. The study conducted by a team led by Matteo Massironi, a researcher at the University of Padua and Italian INAF (National Institute of Astrophysics) associate, was published in the journal “Nature”.

An article just published in the journal “Nature” describes a research on the daily water-ice cycle on the surface of the comet 67P/Churyumov-Gerasimenko and its vicinity. A team of scientists led by Maria Cristina De Sanctis from Rome’s IAPS-INAF (National Institute of Astrophysics – Institute for Astrophysics and Space Planetology) analyzed data collected by the ESA’s Rosetta space probe’s VIRTIS spectrometer discovering that in some areas the ice water disappears in the day and reappears in the night.

A few hours ago, cosmonauts Gennady Padalka and Aidyn Aimbetov and Danish astronaut Andreas Mogensen came back to Earth on the Soyuz TMA-16M spacecraft, landed without problems in Kazakhstan. Padalka spent just over five months on the International Space Station, where he arrived on March 28, 2015 as part of Expedition 43. Aimbetov and Mogensen spent only a few days on the Station, where they arrived on September 4, 2015.
