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 “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.
