The Astronomer's Mirror
John Dee, the polymath and advisor to Elizabeth I, bridged the gap between science and magic. In the late 16th century, he travelled in the circles of astronomy and chemistry as well as occult and alchemical philosophy, helping to define the field of science at the earliest stages of its emergence.
The British Museum, which owns several items of Dee's collection, has completed a study on a peculiar relic, the obsidian spirit mirror. Later in life, Dee was obsessed with speaking with otherworldly forces; this mirror was said to have the divination power to allow communication with fantastical beings. This item is quite similar to Aztec glass found an ocean away, which was thought to be used to speak to the dead.
With the use of X-ray technology, the museum determined that the chemical make up of the obsidian in Dee's glass actually matches obsidian found in Mexico, confirming this connection isn't coincidence. It's likely that Dee, who's interest in the Americas is well known, wished to collect and study this item for himself, fascinated with the cultures of the New World. We can't help but see a bit of ourselves in Dee, as a fellow scientist and collector. You can read more about Dee and his mirror in this great article from the Smithsonian!

Vader’s Lightsaber Becomes the Most Expensive Star Wars Collectible!
Last Thursday, an auction set a new record for Star Wars memorabilia, when a screen-used prop of Darth Vader’s lightsaber sold for over $3.6 million.
Learn About the Tiny Aircraft That Turn Sunlight Into Flight!
Of the five layers of Earth’s atmosphere, the mesosphere (the third layer from Earth’s surface) is a height at which traditional aircraft have, thus far, been unable to reach on their own power. Generally beginning about 154,000 feet above sea level, even the world record for highest aircraft altitude falls about 20,000 feet short. However, a newly developing technology may change this reality, and it involves aircraft that punch high above their weight.
Learn About The Newly Discovered Species of Early Humans!
In studying early human ancestors, known as “hominids,” anthropologists have historically found much wider variations from specimen to specimen than expected, particularly among other paleontological fields. A recent study argues that certain groups of hominid fossils previously thought to be an already discovered species constitute a new one entirely.
