An article published in the journal “Nature” describes the discovery of one of the biggles black holes found so far. Using data collected from the Hubble Space Telescope and the Gemini North telescope in Hawaii, an international team of astronomers discovered a supermassive black hole with a mass estimated at around 17 billion times the Sun in the galaxy NGC 1600. It’s an extraordinary mass considering that it’s inside a galaxy very large but fairly isolated.
An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes the discovery of the first pulsar in the Andromeda galaxy. A team led by Paolo Esposito of INAF-Istituto di Astrofisica Spaziale e Fisica Cosmica, Milan, Italy, found this elusive object using the archives of observations made with ESA’s XMM-Newton space telescope.
An article published in the journal “Astronomy & Astrophysics” describes the discovery of what was called the BOSS Great Wall, a supercluster more than a billion light years long and between 4.5 and 6.4 billion light years from the Earth. With an estimated mass of 10,000 times that of the Milky Way, it’s the largest supercluster discovered so far.
An article about to be published in “The Astrophysical Journal” describes the discovery of the most distant galaxy observed so far. Called GN-z11, it’s about 13.4 billion light years from Earth and that means that we’re seeing the light emitted when the universe was about 400 million years. An international team of astronomers pushed the Hubble Space Telescope to the limit of its possibilities to achieve this result.
An article published in the journal “Astronomical Journal” describes a research that offers at least a partial explanation for the cosmic phenomenon called the Great Attractor. An international team used the 64-meter Parkes radio telescope in Australia to make observations through the galactic Zone of Avoidance, an area of space obscured by the Milky Way itself with its stars and dust clouds. In this way the researchers found hundreds of previously unknown galaxies, ea progress in the gravitational anomaly’s explanation.
