Early this morning (as in, from 2:30-4:30 a.m.) my part of the world was treated to a near-total lunar eclipse. The shadow of the earth crept across the full moon’s surface, eventually turning it a reddish color (due to the refraction of light through the Earth’s shadow). As anyone who has seen a lunar eclipse […]
“They will see that there is in it nothing more than Natural, and nomore than the necessary result of the Motions of the Sun and Moon.” — so wrote astronomer Edmond Halley about the solar eclipse that he predicted for 1715. For millennia, eclipses – especially solar eclipses — had been considered frightening events that
These rocks from the northern shore of Lake Superior are from the dullest period in our planet’s history, apparently. Most of us humans of the early twenty-first millennium do not do well with being bored. Imagine, then, one billion years of it. From 1.8 to 800 million years ago, Earth’s life forms remained relatively

The magnificent ruins shown here are only some of the thousands of Ancient Puebloan structures found in southwestern Colorado’s Canyon of the Ancients National Monument. This particular site, found along the 6.5 mile Sand Canyon (loop) Trail, is similar to many of the region, with remarkable masonry that includes cliff dwellings, towers, public roofed

Here are four different species of finches from the Galapagos Islands. Although they look similar, their differences include their beaks — each one takes advantage of a different type of seed. Natural selection shaped the trajectory of these birds’ appearance, and one of the scientists who first figured out how this worked passed away yesterday

The root system you see here isn’t just part of the plant: it’s joined by fungi, making it a mycorrhiza — a symbiosis of plant and fungi. Most plants rely on mycorrhizae — the fungi elements give the roots better access to precious nutrients like phosphorous and water, and the plant bits give the fungus

TIL that 30 million years ago a species of mound-building termites evolved with next-level techniques that we humans could learn from in order to deal with our environmental challenges. These are the Macrotermes, and what makes them particularly special is the very ancient relationship they co-created with the fungus Termitomyces. Neither survives without the

It’s pleasant, from where I write this post in my ice-bitten and wintery grey state of Pennsylvania, to look at this lovely plant. Here is _Indigofera tinctoria_ the most important plant to make the dye colored indigo — a color that meant beauty to some, but misery to many others. Indigo is one of
This extraordinary scene from a 348-long muslin painting called “Panorama of the Monumental Grandeur of the Mississippi Valley” was done by an American artist named John J. Egan in 1850. Looking carefully at the details, you can see that white Americans are using their black slaves to open up an American Indian burial mound. The

This place looks bucolic and peaceful, no? Hard to believe it’s in a place called hell. This warrants an explanation. What you see here is a photo of part of the Valley of Hinnom, which is located outside of modern Jerusalem. Translated into the Aramaic language, that reads “Gehenna,” which does in fact refer
In 1980 nearly 200 square miles of subarctic meadow, forest, peat bogs, and mountains were set aside to form the Carpathian National Nature Park. Home for many plants and animals in its Alpine climate, the Carpathian National Nature Park is located in Western Ukraine. The park’s great beauty includes glacial lakes and waterfalls, trees like

This painting, from Ukrainian artist “AveOko”, is called “Mofar (3)”, and is a modern rendition of a figure from the Hutsul culture. The Hutsuls, a mountain- and- forest- dwelling people in Western Ukraine, consider mofars to be a type of shamen, using herbalism and folk magic. Mofars are considered neither evil nor good per se,

I adore Medieval flora and fauna mistakes! When they got things wrong, they were so extra about it. So here’s an example of a made-up species that Medieval people thought existed, called the “Barnacle Goose,” or “Branta leucopsis”. Much like the “Lamb of Tartary,” which I did a different post about, the Barnacle Geese
This is a drawing of the prehistoric species Plesiosaurus, discovered by the paleontologist Mary Anning in 1823. Anning was a working-class, uneducated person who became one of England’s premier fossil scholars, but struggled her whole life — financially and professionally — because of her gender and class. Anning grew up on the southern coast

This lovely creature was a Dinogorgon, one of many types of animals known as “Gorgonopsia,” the apex predators in the Permian Period. When I learned about how boss these creatures were, the nine-year-old paleontologist in me felt cheated because of all the front stage play that dinosaurs get. But these animals were amazing and thrived
This is a colorized photograph of an unusual geographic formation that no longer exists — but for hundreds of years, it marked a major river system in the southern part of the U.S.. Known as “the Great Raft”, it was a terrific log jam, made up of season upon season of washed-away trees. Cedar, cottonwood,
Today is April 20, aka 4/20, which has been associated in the US since the 1970s with marijuana. Here, we are in a transition phase regarding weed’s medical and recreational legalization, with some states allowing and others forbidding. But in the Middle Ages no regulation or moral questioning of the plant existed. Medieval Europeans
In the Khentii Mountains of Mongolia, the almost 8,000 ft-peak Burkhan Khaldun lies: it is the legendary burial place of Genghis Khan, one of Eurasia’s most ambitious and brutal rulers. From a distance of 800 years, it is easy to allow awe rather than horror to surface as the primary estimation of the Mongolian warlord.

Everyone knows that the Medieval aristocracy was famed for the way they promoted the military prowess of knights on horseback. Gargantuan sums of money were spent selecting, breeding, and caring for war horses that could show off the status of their aristocratic riders. There is, therefore, a certain amount of glee to be taken by

So much of the preserved natural beauty of the U.S. can be traced back to the FDR Depression-era Civilian Conservation Corps, and this remote jewel of state park is another example.
