- ASPIDISKE (Iota Carinae). Most stars have no proper name; even some bright ones lack them. How they would envy this one, with not one, but THREE, from each of the classic stellar languages. “Aspidiske” (the Greek Iota star in Carina, the Keel of the ship Argo) comes from the Greek, and means “little shield” (referring to a decoration, not a defensive weapon).
- Quaternary (Wikipedia)
The Quaternary (/kwəˈtɜːrnəri, ˈkwɒtərnɛri/ kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. As of 2023, the Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a third epoch, the Anthropocene, has recently been proposed, but it is not officially recognised by the ICS.
