The multinational Hittite Empire and the powerful theocratic Ramesside monarchy of Egypt clashed along the shores of the eastern Mediterranean during the Late Bronze Age. Numerous sources shed light on how the Egyptians mea-sured time during that period through their civil calendar. Interestingly, this calendar more or less followed the rhythm of

Stellar occultations, when a distant object passes in front of a star and casts a shadow on Earth, are a powerful tool to probe the physical properties of solar system bodies. They enable precise size and shape measurements and can reveal rings, satellites, atmospheres, or surface features. Here we present results from two stellar occultations by

Non-uniformity plays an important role for MHD waves. For a uniform plasma of infinite extent the MHD waves can be subdivided in two classes with distinct properties. The first class contains the Alfvén waves. The Alfvén waves are incompressible and propagate parallel vorticity. They do not have a parallel component of displacement, they do not
