Braids of shimmering dust, painting the ancestral tapestry of the sky.
Until the 16th century, comets were deemed a celestial omen prophesizing disaster. Today, we know that a comet is simply a frozen lump of ice and dust wandering the vastness of the universe. However, as soon as a comet approaches a star, two shining tails emerge along its path. The intense heat of the star strips away its icy exterior, transforming it into a tail of gas that points away from the star. The largest particles torn away from the comet’s surface get left behind, forming a second tail along the trajectory.
This cosmic wanderer is beautiful, but it can also be merciless: the impact of a mountain-sized comet can turn any planet into an inferno and eradicate all its inhabitants. They might even see it coming, but how can they survive the impact?
