First direct detection of relativistic particles accelerated in shocks in the heliosphere described in the study: “Direct Measurements of Synchrotron-emitting Electrons at Near-Sun Shocks” of I. C. Jebaraj (University of Turku)

In the Universe, various environments are characterized by shocks capable of converting the kinetic energy of gas and particle flows into heat, turbulence, magnetic energy, and, ultimately, accelerating particles to relativistic energies, producing cosmic rays. The sizes of these systems can vary by many orders of magnitude, ranging from the typical dimensions of the interplanetary environment to the enormous galaxy

Confirmed the existence of a neutron star in the center of SN1987A. The paper: “Additional Evidence for a Pulsar Wind Nebula in the Heart of SN 1987A from Multiepoch X-Ray Data and MHD Modeling” of E. Greco (University of Amsterdam; INAF-OAPA) recently appeared on Apj

SN1987A, the supernova exploded in the Large Magellanic Cloud (at about 170000 light years of distance) on February 23rd 1987, was an iconic event for the study of supernovae and supernova remnants. In fact, it is the only case where it was possible to observe (with telescopes) the explosion and to follow with periodic observations the evolution of the supernova
