One of history's leading 16th-century astronomers, Tycho Brahe, was also an alchemist who kept the secrets of that pursuit under wraps. AdvertisementAfter his death, Brahe's elaborate laboratory and observatory was destroyed, taking many of its secrets with it. Rasmussen and colleagues recently analyzed the shards for evidence of 31 trace elements to determine which Brahe may have used in his laboratory. In addition to medical experiments, Brahe could have been trying to uncover the secrets of other minerals. The endless search for better medicineTycho Brahe's laboratory was destroyed after his death.

Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. Thousands of years ago, our ancestors produced the first maps of the stars and practiced alchemy, the precursor to chemistry. But ancient alchemists actually developed technology and discovered chemical elements that are still widely used today. Now, a new discovery links both astronomy and alchemy in one intriguing figure who lived during the Renaissance. Once the Starliner mission concludes, SpaceX will ferry a quartet of astronauts for NASA’s Crew-9 mission to the space station.

The covert nature of Brahe’s work was common among alchemists of the Renaissance, who kept their knowledge close to the vest. “Tungsten had not even been described at that time, so what should we infer from its presence on a shard from Tycho Brahe’s alchemy workshop?” Rasmussen said. In addition to serving as Brahe's home, Uraniborg functioned as a scientific center where students across Europe came to live and work. And Brahe himself wrote that the king was eager to support the scientist’s work in both astronomy and alchemy. Given the amount of gold found in Brahe’s remains, he may have also taken medicine containing potable, or drinkable, gold.
