NASA Unveils Decades-Long Video of Exploding Star's Expansion

• NASA released a remarkable time-lapse video of Kepler’s Supernova Remnant, observed for over 25 years using Chandra X-ray images from 2000-2025.
• The video shows hot debris expanding outward from a Type Ia supernova, revealing complex structures and varying expansion speeds due to interstellar material.
• First recorded in 1604 by Johannes Kepler, this supernova scattered elements crucial for forming new stars and planets across space.
• Decades of Chandra observations allow scientists to study the remnant's real-time evolution, understanding cosmic explosions and element mixing.
• The footage inspires wonder, transforming centuries-old cosmic events into a visually stunning and comprehensible story of the universe.
