The pulsar SXP 1062

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes the first observation of an irregularity in the rotation period of a pulsar, a phenomenon called glitch, in a binary system. A team of scientists from the Middle East Technical University and Baskent University, both in Ankara, Turkey, used data collected from observations of the Swift, XMM-Newton and Chandra space telescopes conducted over two years to identify glitches in the pulsar SXP 1062.

An article published in the journal “Nature” describes a research on the auroras on the planet Jupiter and on the differences with those on Earth. A team of researchers led by Barry Mauk of the Johns Hopkins University Applied Physics Laboratory investigated data collected in particular by two instruments aboard NASA’s Juno space probe finding traces of remarkable electrical potentials. They’re aligned with Jupiter’s magnetic field, which accelerates the electrons towards the atmosphere at energies even tenths times higher than those of the Earth’s auroras.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research that revealed a surprise in the origin of electromagnetic radiation from the Crab Nebula that can influence the research on cosmic rays. Federico Fraschetti of the University of Arizona, USA, and Martin Pohl of the University of Potsdam, Germany, believe that the model created by Enrico Fermi in 1949 is to be partially revised because those radiation are produced in a way different from what was thought.
