An article published in “Astrophysical Journal” describes the analysis of the supernova remnant G1.9+0.3, the youngest observed in the Milky Way. A team of astronomers from Harvard University used data collected by NASA’s Chandra space telescope and the VLA radio telescope to find evidence that it’s an explosion triggered by the merger of two white dwarfs, what is called a Type Ia supernova.
An article published in the journal “Nature” describes a research that made it possible to map the climate on the exoplanet 55 Cancri e. It’s a planet already well known for the many studies carried out in recent years, in this case the Spitzer Space Telescope was used to try to get a better idea of the existing temperatures on the surface of this super-Earth. They can reach extreme levels, estimated between 1,400 and 2,700 Kelvin.
An article published in “Astrophysical Journal Letters” describes a research on a forming protoplanet in the TW Hydrae star system. By using the ALMA radio telescope, a team led by Sean Andrews of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, obtained the best image of a protoplanetary disk produced so far.
At the 47th Lunar and Planetary Science Conference held last week in The Woodlands, Texas, the latest news about the mountains of Titan, the largest of Saturn’s moons, were presented. NASA also presented the progress made in creating maps of this moon, a task that has to face a number of problems. All these works are based on data collected by the Cassini space probe.
At the 47th Lunar and Planetary Science Conference held last week in The Woodlands, Texas, new results were presented of the analyzes of data collected about the dwarf planet Ceres by NASA’s Dawn space probe. Some of the mission scientists presented a new color map of Ceres surface and new highly detailed pictures of Occator crater, famous for the presence of the largest among the white spots, but also other interesting craters, especially Oxo, where water was found.
