New research led by Bournemouth University archaeologists supports the theory that the Hyksos, the rulers of the 15th Dynasty of ancient Egypt, were not from a unified place of origin, but Western Asiatics whose ancestors moved into Egypt during the Middle Kingdom, lived there for centuries, and then rose to rule the north of Egypt.

When the Moon formed into a sphere approximately 1,700 km in radius 4.425 billion years ago, its interior heated up considerably due to the energy released when it accreted. The rock melted and an ocean of magma, possibly more than 1,000 km deep, formed. Later, light rocks crystallized, which rose to the surface and formed a first crust on the Moon. This crust insulated the Moon from space, and the magma ocean beneath it cooled down slowly. Around 200 million years would pass before the Moon completely solidified.

An artist’s impression of a thermonuclear supernova: the material ejected by the supernova will initially expand very rapidly, but then gradually slow down, forming an intricate giant bubble of hot glowing gas; eventually, the charred remains of the white dwarf that exploded will overtake these gaseous layers, and speed out onto its journey across our Milky Way Galaxy.

This Hubble image shows the free-floating evaporating gaseous globule J025027.7+600849. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
