Tania Borealis (stars.astro.illinois.edu)
TANIA BOREALIS (Lambda Ursae Majoris). Three pairs of unrelated stars mark the feet of Ursa Major, the Great Bear. To the Arabs, they marked the “leaps of the gazelle,” the first, second, and third leaps proceeding from east to west. Tania Borealis (Lambda Ursae Majoris) is the more northerly of the stars that make the “Second Leap,” the name from a long phrase that means just that (plus the Latin for “northern”).- Xenon (Wikipedia)
Xenon is a chemical element; it has symbol Xe and atomic number 54. It is a dense, colorless, odorless noble gas found in Earth’s atmosphere in trace amounts. Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.
