An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research for possible planets in formation orbiting the pulsar Geminga. The astronomers Jane Greaves and Wayne Holland used the James Clerk Maxwell Telescope (JCMT) in Hawaii to conduct observations at submillimetric wavelengths and understand the mechanisms of planet formation in a system after a supernova.

Two telescopes in Hawaii were used for new observations of the planet Jupiter and in particular of its famous Great Red Spot. They were conducted to support NASA Juno space probe’s mission, which on July 10 will fly over the giant jovian storm. The Gemini North telescope was used with special near-infrared filters to produce specific colors that can penetrate Jupiter’s upper atmosphere and clouds. The Subaru telescope’s COMICS instrument was used with mid-infrared filters.

NASA’s Mars Rover Opportunity is working in an ancient valley on the edge of Endeavour Endeavour’s rim called “Perseverance Valley” examining rocks and driving around the area to carry out a survey of the place. According to plans, once these tasks are completed Opportunity will go down to the lower part of the valley but the maneuver will have to be even more cautious than expected due to a problem encountered in one of the wheels’ steering system.

At a press conference, NASA presented the new catalog of exoplanet candidates produced thanks to the observations of its Kepler space telescope. Exoplanet candidates are a total of 4,034 of which 2,335 have been confirmed as actually existing. There are 219 new candidates, of which 10 might be similar to Earth and at the same time be in ​​their solar system’s habitable zone.

An article published in the journal “Earth and Planetary Science Letters” describes a study of the first samples taken in the lower layers of Mount Sharp on Mars by NASA’s Mars Rover Curiosity. A team of scientists in the ARES Division at NASA’s Johnson Space Center compared the minerals found in the first samples analyzed, which show the different environmental conditions that existed over time.
