A brinicle, also commonly known as an “ice stalactite” forms under the sea ice when a flow of extremely cold saline water is introduced to ocean water. It is known as an ice stalactite because it is the undersea equivalent of a hollow stalactite. It freezes everything it touches, including sea creatures.
Hedyphane
Varying from white to yellowish with occasional reddish or green specimens, it was named after its discovery in Sweden in 1830 from the Greek words for ‘appearing beautiful’. It is a rare critter, only forming in manganese or zinc ore deposits that have been metamorphosed by heat and pressure deep within the crust, or when intruding granites bake the surrounding rock. It is a part of the apatite group (see http://bit.ly/2akYWkg)and includes lead and calcium combined with arsenic and oxygen in its composition, being an analogue of another pretty mineral called mimetite (see http://on.fb.me/1zo1vvI).

The brightest star in the constellation Leo is Regulus, and it is also one of the brightest stars in the night sky, with only 21 stars brighter. Regulus is strictly speaking a star system, composed of Regulus A, the source of its brightness and a white dwarf companion that has not yet been observed, and to other stars too dim to be easily visible. Also known as Alpha Leonis for its primary position in the constellation, the name Regulus means ‘little king’ or ’kinglet’ and also occasionally prince. Regulus derives from the Latin word rex, regis, taking the diminutive form.
Regulus A is a large, hot star, about 4 times as wide as our sun but much brighter and with over 1000 times the energy output. Regulus A is also spinning about 1000 times faster on its axis and shooting through space like a bullet! Scientists are unclear what the source of this energy and movement is.

One Yowah nut, bisected
One of many opal mining sites in the red continent is called Yowah, and is famous for its opal nuts, veins of precious glowing opal within nodules of siliceous ironstone that often form amazing patterns. They vary from 0.5 to 20 cm across, and occur in an iron rich sandstone, near the border with an adjoining mudstone.
