This handout picture provided by NASA on January 31, 2025 shows asteroid 2024 YR4 as observed by the Magdalena Ridge 2.4m telescope at the New Mexico Institute of Technology on January 27, 2025. A colossal explosion in the sky, unleashing energy thousands of times greater than the Hiroshima bomb. A blinding flash that momentarily outshines the Sun. A shockwave powerful enough to flatten everything for miles. There's a small but real chance this apocalyptic scenario could unfold in eight years -- if a newly detected asteroid, nearly the size of a football field, collides with Earth. While there's no immediate cause for alarm, scientists are watching closely.
