- NASA recently shared video capturing aurora lights across Mars planet at night.
- The images showed how magical aurora lights covered the red planet with purple hue.
- These images were captured by NASA's MAVEN (Mars Atmosphere and Volatile Evolution) orbiter.
- Auroras are colourful lights which are visible when energy particles emanating from solar storms travel down the magnetic field lines of a planet.
- Mars lost its internally generated magnetic field in the ancient past, so there’s no protection from the barrage of energetic particles.
- When charged particles hit the Martian atmosphere, it results in auroras that engulf the entire planet.
