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.
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”.
An article published in the journal “Astrophysical Journal Letters” describes the most precise measurement so far carried out of the mass of a supermassive black hole. A team led by astronomer Aaron Barth of the University of California, Irvine (UCI) used the ALMA radio telescope to examine the supermassive black hole at the center of the galaxy NGC 1332.
An article published in the journal “Nature” describes the discovery of a solar system with three rocky planets that orbit the star TRAPPIST-1, a really small ultra-cool dwarf. A team led by Michaël Gillon of the Institut d’Astrophysique et Géophysique at the University of Liège in Belgium, found these planets with sizes and surface temperatures similar to those of the Earth using the TRAPPIST telescope at ESO’s La Silla Observatory in Chile.
An article published in the journal “Science Advances” describes a research about comet C/2014 S3 (PANSTARRS), which was preserved in the Oort cloud for billions of years while maintaining almost the same features it had at the time of its formation. Its peculiarity is that it seems to be composed of the same materials of the inner areas of the solar system so it’s a kind of fossil of the times of the Earth’s formation.
