An article published in “The Astronomical Journal” describes a research on a trans-Neptunian object called 2007 OR10. A team of astronomers used NASA’s Kepler space telescope and archive data of ESA’s Herschel space telescope’s observations to study this celestial body. The result is that they discovered that it’s much bigger than it looked and is probably a dwarf planet.
An article published in the journal “Science” describes the first direct observation of the phenomenon called magnetic reconnection. NASA’s four MMS twin space probes allowed to obtain the best observations made so far of the interaction between the Earth and Sun’s magnetic fields. According to the researchers who analyzed the data collected, electrons trigger this phenomenon.
It was afternoon in California when the SpaceX Dragon spacecraft ended its CRS-8 (Cargo Resupply Service 8) mission for NASA splashing down without problems in the Pacific Ocean about 420 km (about 260 miles) off the coast of California. The Dragon left the International Space Station a few hours before, when in California it was morning.
Yesterday, NASA held a press conference to announce that 1,284 exoplanets have been verified among the candidates discovered using its Kepler space telescope. It’s by far the largest number of planets added to the already long list of the known ones. An article on this discovery has just been published in “The Astrophysical Journal”.
NASA’s MESSENGER mission has published the first complete topographical map of the planet Mercury. To be precise, it’s a Digital Elevation Model (DEM), a representation of the elevation distribution of territory, or of another surface, in digital format. It’s the product of the processing of data collected by the MESSENGER space probe during its mission ended just over a year ago.
