Scientists report that they may have found the earliest written record of a solar storm in ancient Assyrian tablets. Recent analyses have found evidence of an extreme solar storm that left energetic particles in tree rings and ice cores across the world sometime around 660 BCE. With this in mind, a research team in Japan and the United Kingdom wondered if they'd be able to find evidence of this storm in ancient astrological records — and they may have found something in Assyrian tablets. Back in the 19th century, archaeologists uncovered thousands of tablets dating back to the Assyrian empire in Mesopotamia, which documented treaties, stories, including the now-famous epic of Gilgamesh, and astrological reports.
