In this important Geography + Space Science session, Prince Sir explains the complete concept of Aurora Light—its formation, causes, types, locations, colors, and exam-oriented facts.
Auroras are a frequently asked topic in BPSC TRE 4, BPSC Prelims, SSC, BSSC, Railway, and all environment–geography-based exams.

📚 What You Will Learn
🔸 1. What Are Auroras? (ऑरोरा क्या होते हैं?)

✔ Natural light display in Earth’s sky
✔ Occur near polar regions
✔ Caused by charged particles from the Sun
✔ Solar wind + Earth’s magnetic field interaction

🔸 2. Types of Aurora
✔ Aurora Borealis (Northern Lights)

– Location: North Pole
– Countries: Norway, Iceland, Canada, Alaska, Russia

✔ Aurora Australis (Southern Lights)

– Location: South Pole
– Countries: Antarctica, Australia, New Zealand, Chile

🔸 3. How Are Auroras Formed?

✔ Solar wind releases electrons & protons
✔ These particles hit Earth’s magnetic field
✔ Energy released as colorful light
✔ Happens in ionosphere (80–300 km altitude)

🔸 4. Colors & Their Scientific Reason

✔ Green → Oxygen
✔ Red → High-altitude oxygen
✔ Blue / Purple → Nitrogen
✔ Pink → Oxygen + nitrogen mix

🔸 5. Why Auroras Occur Only at Poles?

✔ Magnetic field strongest at poles
✔ Charged particles get directed towards polar atmosphere

🔸 6. Most Expected MCQs (BPSC TRE / Prelims)

✔ Aurora Borealis is seen in which region?
✔ Aurora occurs due to interaction of what?
✔ Aurora Australis is found where?
