- Doggerland was a large area of land in Northern Europe, now submerged beneath the southern North Sea. This region was repeatedly exposed at various times during the Pleistocene epoch due to the lowering of sea levels during glacial periods. However, the term “Doggerland” is generally specifically used for this region during the Late Pleistocene and Early Holocene. During the early Holocene following the glacial retreat at the end of the Last Glacial Period, the exposed land area of Doggerland stretched across the region between what is now the east coast of Great Britain, the Netherlands, north-west Germany, and the Danish peninsula of Jutland. Between 10,000 and 7,000 years ago, Doggerland was inundated by rising sea levels, disintegrating initially into a series of low-lying islands before submerging completely. The impact of the tsunami generated by the Storegga underwater landslide c. 8,200 years ago on Doggerland is controversial. The flooded land is known as the Dogger Littoral.
- Beta Carinae (Wikipedia)
Beta Carinae is the second-brightest star in the southern constellation of Carina. It has the official name Miaplacidus; Beta Carinae is the star’s Bayer designation, which is Latinised from β Carinae and abbreviated Beta Car or β Car. With apparent magnitude of 1.69, it is one of the brightest stars in the night sky. It is the brightest star in the southern asterism known as the Diamond Cross, marking the southwestern end of the asterism. It lies near the planetary nebula IC 2448. Parallax measurements place it at a distance of 113.2 light-years (34.7 parsecs) from the Sun.
