NASA’s Mars Rover Opportunity has begun its scientific work in yet another Mars area to be explored during a mission that has been going on for over 13 Earth’s years. This mission was extended for the tenth time in 2016 and now its goal is to study “Perseverance Valley”, an ancient valley on the inner slope of the Endeavor crater’s rim to figure out how it formed.

An article published in the journal “Science” describes a research on the exoplanet HAT-P-26b, a warm Neptune, meaning a planet of size similar to Neptune that orbits near its star HAT-P-26. A team of researchers from NASA’s Goddard Space Flight Center and the British University of Exeter used the Hubble and Spitzer space telescopes to discover what is called a primitive atmosphere for HAT-P-26b despite its star being old.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes the discovery of a large wave of hot gas in the Perseus galaxy cluster that extends for about 200,000 light years. A team of astronomers led by Dr. Stephen Walker of NASA’s Goddard Space Flight Center combined observations with NASA’s Chandra X-ray Observatory and others at radio frequencies with computer simulations to study it.

The first results of the analysis of the data collected by the Cassini space probe during its dive into the space between the planet Saturn and its rings on April 26, 2017 provided a remarkable surprise. The researchers discovered that Cassini’s instruments recorded very few particles during the crossing of that space and all of them were tiny, around a micron across. This is a mystery to which the researchers hope to find an explanation.
