The Tsar witnessed a cross-shaped celestial sign on the Red Porch, interpreting it as a forewarning of his impending demise.
Reports indicate that Ivan the Terrible gazed at the comet for an extended period, a common observation practice for such astronomical phenomena.
Leading researcher Nathan Eysmont from the Institute of Space Research of the Russian Academy of Sciences revealed that the comet either disintegrated as it neared the Sun or traveled far into the depths of space.
