After extending the mission of the venerable Mars Rover Opportunity another time, NASA announced that it will drive down a gully dug by a fluid a long time ago, maybe by water. The goal is to understand whether this is the remains of an ancient Martian river. It’s the beginning of yet another mission for Opportunity, which suffers wear and might be at risk because of a storm that will hit Mars.

An article published in “The Astrophyisical Journal” describes the discovery of the first gamma-ray binary found outside the Milky Way, called LMC P3. A team of researchers led by Robin Corbet at NASA’s Goddard Space Flight Center used the Fermi space telescope to discover this couple in the Large Magellanic Cloud formed by a giant blue star and a companion that might be a neutron star or a black hole that are interacting producing cyclic gamma-ray emission.

In a press conference, NASA announced that a team of astronomers led by Dr. William Sparks who observed Europa with the Hubble Space Telescope captured images of what might be plumes of water vapor and erupt from the surface of this planet moon Jupiter. They would be a confirmation of the existing subsurface activity with an ocean of liquid water, one of the best candidates to host life forms. The results of this research will be published in the “Astrophysical Journal”.

NASA published a series of photographs taken by the Mars Rover Curiosity that show the landscape of the Martian area called “Murray Buttes”. Those are very high quality images captured on September 8, 2016 using the Mast Camera (MastCam) instrument, consisting of two cameras able to get among other things photographs in natural colors. The result is a breathtaking view which at the same time is very interesting from the scientific point of view because the photographed stratified rocks show traces of Mars’ geological history.

Two new research are connected in different ways to emissions coming from the dwarf planet Pluto. An article published in the journal “Icarus” describes a research which, through the use of the NASA’s Chandra X-ray Observatory, detected X-rays emissions from Pluto. Another article published in the journal “Nature” offers an explanation for the reddish color to Charon’s poles, caused by methane ripped from Pluto’s atmosphere and turned into ice by the low temperatures.
