1572 ( MDLXXII ) was a leap year starting on Tuesday of the Julian calendar, the 1572nd year of the Common Era (CE) and Anno Domini (AD) designations, the 572nd year of the 2nd millennium, the 72nd year of the 16th century, and the 3rd year of the 1570s decade.
The Answers of Patriarch Jeremiah given to Martin Crusius, Professor in Tübingen, and other Lutherans, in 1572, are approved by the Synod of Jerusalem, as they were by the Synod of Jassy, and thus clothed with a semi-symbolical authority.

The evolution of young SNRs, traced by its expansion parameter, depends mostly on the hydrodynamic structure in terms of pressure, velocity, and density of the interaction region (bounded by the forward and reverse shocks). It depends on a few key parameters, related to the ambient medium density and structure (interstellar medium, stellar wind fro...
The ejecta X-ray line emission (intensity, energy, and line ratios) provides constraints on the supernova yields and on the emitting conditions, which are related to the properties of the supernova and its subsequent evolution as a remnant. It can thus provide constraints on the explosion mechanism. The global X-ray spectrum of Tycho’s SNR (see Fig...
Tycho’s SNR has been at the forefront of discoveries regarding particle acceleration in supernova remnants. First, Chandra observations (Hwang et al. 2002) revealed the presence all along the forward shock of a thin high-energy filament, spectrally featureless. It resolved, with its high-spatial resolution, the morphology of the high-energy rim sho...
Tycho’s supernova remnant is one of the few young galactic Ia remnants, still dominated by the ejecta emission, as the same time as experiencing efficient particle acceleration at its forward shock. As shown previously, the acceleration of particles at the forward shock impacts the shock properties and the overall hydrodynamical structure of the sh...

Sep 12, 2023 · Tycho Brahe's meticulous and detailed recordings of the change in brightness of the new star allowed modern astronomers not only to classify SN 1572 as a supernova event, but also helped to pinpoint the exact astrometric location of SN 1572.
1572 AD St. Bartholomew's Day Massacre On August 23 and 24th Catholics in France killed 50,000 Hugenonts in Paris and the provinces. The massacre was called for by the queen mother Catherine de Medici and is applauded by Pope Gregory XIII.
