Under a sprawling swathe of salt-white desert observable from outer space lays one of our planet’s greatest lithium deposits. Bolivia’s Salar de Uyuni, which holds over ten billion tons of salt covering nearly 5,000 square miles, is typically famous for being able to transform into the Earth’s largest mirror 🪞 The watertight desert pools rainwater during Bolivia’s wet season and the still, expansive surface reflects the dreamy cloudscapes of the bright desert sky. But the blanched white desert is also a massive repository for lithium— 17% of the planet’s reserve are concentrated beneath the bone-colored desert. 🏜️

Minute quantities of lithium are scattered throughout soils across the globe, but in most cases, the lithium is so diffuse that attempting to mine it would never be sufficiently efficient. This is solved by its natural abundance in salt brines around the world. Lithium is crucial in powering sustainable electric technology, namely, electronic vehicles. Industrial scale lithium is harnessed from salt-flat brines through a process of evaporation and chemical recovery, and producing battery-grade lithium from brine involves separating out sodium chloride, potassium chloride, and magnesium chloride. Lithium is also recovered from lithium-bearing ores, such as spodumene, through a process that involves crushing, roasting and acid leaching.

Lightning strikes zigzag across the sky in all manners of shapes and brightness, flashing through the clouds in quick, brilliant flares of color. But what gives lightning is momentary, intense color? ⚡️

Lightning colors are produced through gas excitation in the atmosphere. Pockets of positive and negative charge develop within cumulonimbus clouds, and eventually grow so large that they trigger an opposite charge at a point on the ground below. Nitrogen, the dominant gas in the atmosphere, is excited by this sudden surge of energy. The electrons move to higher energy states as the spontaneous heat of lightning splits through the skies. The familiar blue-white of lightning bolts occurs when the electrons calm, discharging a searing flash of light before returning to their original energy states.

We perceive lightning as a flash of light because of its simultaneous incandescence
(due to its high temperature, it’s literally white-hot, giving it a vibrant glow) and its luminescence through the excitation of nitrogen gas in the atmosphere.

Different particles scatter this light and give the lightning blue, pink, purple, white or even a brown-ish coloration. Strikes that are closer to you generally appear white, because there's less atmosphere to pass through before the light reaches your eyes. It’s even possible to see more pink or green bolts during snowstorms, as snowflakes tend to bend the light more.

Life, and all its dazzling, accompanying color, can be traced to the deep reaches of outer space. 🔭🌌

All space’s stars, light, gas and dust make for a thermodynamic atmosphere that produces some of the largest scale chemical reactions— and kaleidoscopes of color— known to humankind.

Here in the Crab Nebula, we can see neon among the filaments that are remnants of the origin star's atmosphere, alongside ionised helium and hydrogen, and carbon, oxygen, nitrogen, iron, neon and sulfur.

Some of the colors we see throughout our world, and the universe at large, come from simple chemical elements that are the building blocks of all matter and material.

One such chemical compound is hydrogen. Hydrogen is the simplest and most abundant element in the Universe (a Hydrogen Atom has one electron and one proton), and all other elements are made in stars through Nuclear Fusion at different stages and temperatures in the life-cycle of a star.

A proton is a positively charged subatomic particle, while an electron is a negatively charged and less massive particle. These types of electrons can exist in a range of energy states, from low to high. When they cycle to lower energy states in a phenomenon called electron decay, the lost energy is emitted as photonic light particles that change color depending on their energy. The higher the energy, the bluer will be the photon; the lower the energy, the redder it will be.

We can see this in the radiation from a hot star causes hydrogen gas in a nebula to glow with a pinkish-red color. The Orion Nebula Hydrogen gas and dust emanates a gorgeous red from different bright spectral lines of hydrogen gas.

Ever look to the night sky and see this natural wonder? Famed the world over, the Aurora Borealis— which can be etymologically traced to Latin as “morning light”— is one the nature’s greatest color marvels. 🌌

The vibrant streaks of color that illumine the northern skies are due to interactions between protons and electrons, which are charged from the sun, with the ionized part of Earth’s upper atmosphere. Turbulence on the sun pull on Earth's magnetic field, causing a rippling effect known as Alfvén waves that catapult electrons into Earth's atmosphere, where they create the aurora. ¹

When there’s high solar activity, the color produced from the Northern Lights is even more resplendent. While it’s common to see them in dark, clear winter nights, you can find the luminescent phenomena in skies across Alaska, Canada, Iceland, Greenland, Norway, Sweden and Finland as early as August. ²

Being the black sheep isn’t so bad! Animals can sometimes be darker than others in their species due to a condition called melanoma. Melanism is a recessive biological function that crops up across the animal kingdom in mammals and birds. The dark-colored pigment— called melanin— is developed in the skin and fur, giving off a dark or black-colored appearance.

Melanism is known to give animals certain advantages, such as greater immunity against diseases, and higher absorption of heat from sunlight – a good adaptation for animals living in high altitudes.

Perhaps the most well-known shade of the cascading wisteria flowers is lavender blue, but many different cultivars have arisen that showcase nature’s artistry!

Wisterias come in white, pink and violet too. All varieties feature fragrances, which can range from musky to sweet.

Wisteria species are only native to a handful of areas scattered around the world. Korea, Japan, and China are the native range for the Asian varieties. In these regions, the plant is loaded with cultural meaning— in Korea, the Wister flower signifies eternal devotion. The Japanese also consider Wisteria a symbol of good luck, success, and longevity.

Polar stratospheric clouds are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 m (49,000–82,000 ft). They are best observed in winter and in more northerly latitudes, like in the Arctic and Antarctic, when the Sun hits between 1 and 6 degrees below the horizon, shining dwindling sunrise or twilight rays through small ice crystals that are carried along a jet of stratospheric air. ❄️

Their iridescence comes from the forward scattering of sunlight, which deflects electromagnetic waves within the atmosphere.

Polar stratospheric clouds, clouds, long known to play an important role in Antarctic ozone destruction, are occurring with increasing frequency in the Arctic. These high altitude clouds form only at very low temperatures help destroy ozone in two ways: they provide a surface which converts benign forms of chlorine into reactive, ozone-destroying forms, and they remove nitrogen compounds that moderate the destructive impact of chlorine. ²
