Hopper crystals form when the outer edges of a crystal grow much faster than the center of its faces, creating a hollow, stepped, or staircase-like skeletal structure.

Voting for #halite in #MinCup26 🧪⚒️ because thick layers of halite can be used to store hydrogen as a low carbon fuel! Low permeability so the H₂ stays put, large caverns can be created (just add water!) and it has a smaller engineering footprint compared to options on the surface. buff.ly/npFpSAG

Juice used the gravity of our home planet to alter its route to Jupiter using very little fuel. The flyby deflected Juice by an angle of 20° compared to its pre-flyby path and increased its velocity by 3.5 km/s. 🔭 🧪

Infographic showing Juice's flight past Earth with a dotted orange line. Key timings are indicated, including the start of the flyby navigation campaign (17 August), the closest approach to Earth (28 September) and the farewell images of Earth (2 October). Some of the line is bold yellow, a key indicates that this means that Juice's science instruments are switched on.

Going for #halite today in #MinCup26 🧪⚒️ because it's cool that you can make a mineral at room temperature (in comparison #zircon forms at ~800°C which is definitely not lickable). So, you can make it in your kitchen or you can make it on an industrial scale like here at Lake Grassmere in NZ 🇳🇿

AUSTRALIA and beyond - We need to assemble again for #Putnisite! This amazing structure needs your support in today's #MinCup26 battle. For shear density and novelty in its strange/wonderful crystal structure it should get your vote over #Julienite

Image representing the crystal structure of putnisite - here red spheres represent oxygen atoms, light blue spheres/polygons represent calcium atoms, dark blue spheres/polygons represent silicon atoms, brown spheres/polygons represent carbon atoms, green spheres/polygons represent strontium atoms. There is also some chromium hiding in the structure that is in part represented by a yellow triangle. The representation is drawn in VESTA from entry #20044 in the American mineralogist database

Image representing the crystal structure of julienite - here red spheres represent oxygen atoms, dark yellow spheres/polygons represent sodium atoms, dark blue spheres/polygons represent cobalt atoms, yellow spheres represent sulfur atoms, brown spheres represent carbon atoms and light blue spheres represent nitrogen atoms. The structure is viewed down its c axis and shows that there are sodium/water(oxygen) units surrounded by cobalt complexes with nitrogen, carbon and sulfur attached.

Widgiemooltha is a 1897 historic town in Western Australia’s goldfields that arose during the gold rush, & was named the aboriginal name for a nearby hill. This pretty purple putnisite crystal was found there. This mineral has a completely unique chemical structure found nowhere else in nature.

This tiny purple putnisite crystal is from the Armstrong Ni Mine, Widgiemooltha, Coolgardie Shire, Western Australia, Australia. It is unique in chemistry and nature, and found nowhere else. From Mindat: https://www.mindat.org/photo-543393.html

10 June marked 140 years since the volcanic ⚒️🧪 eruption of Mt Tarawera near Rotorua 🇳🇿. My main memory of this famous image is as a slide in 1st year geology course where the lecturer pointed out the figures in the middle: 'Look how excited they are! They must be volcanologists!'

A vivid 19th‑century illustration of Mount Tarawera erupting at night, with bright red and orange lava and ash shooting into a dark sky. The fiery glow reflects across a calm lake in the foreground. Small huts and figures from the village of Wairoa stand near the water’s edge, dwarfed by the dramatic volcanic explosion.

Chromolithograph based on a painting by Charles Blomfield, depicting the volcanic eruption of Mount Tarawera on June 10, 1886, seen from the village of Waitangi, Lake Tarawera. The chromolithograph was made by William Potts, and was published in E. Wakefield’s publication 'New Zealand Illustrated', published by A.D. Willis Ltd in 1889.
