The precious paper was a letter penned by Italian scientist Galileo Galilei, which included sketches of Jupiter’s moons.The library acquired the letter in 1938 and considered it a prized possession because it was evidence of Galileo’s thought process as he worked toward his understanding that the planets revolved around the sun.But a historical detective sensed it was a fake and one of many manuscripts or documents tha ...read more

The woolly rhinoceros, which roamed northern Eurasia for millions of years, is one of the most iconic extinct megafauna. The formidable thick-skinned, long-furred beast occupied the mammoth steppe, a cold-dry grassland biome that existed during the Last Glacial Maximum (LGM). However, roughly 10,000 years ago the woolly rhinoceros vanished. Scientists have been able to identify mummified carcasses of these animals, along with bone fragments, and several human cave paintings in Europe and Asia fe ...read more

Jupiter’s Great Red Spot is one of the most famous and spectacular sights in the Solar Systems. Wider than the diameter of the Earth, the spot is a giant vortex of winds up to 400 kilometers per hour. Its reddish color probably comes from complex organic molecules that form in its upper atmosphere, although nobody is quite sure.The Spot may have first been seen by the Italian astronomer Giovanni Cassini in 1665 and then observed throughout his life until his death in 1712. But after that somet ...read more
