While sticking your tongue out is considered rude in many cultures, in Tibet, it is a long-standing sign of respect and a friendly welcome.

The Historical Origin:

• 👑 It dates back to the 9th century, starting with an unpopular King named Lang Darma, who was said to have a black tongue
• 👺 Buddhists began sticking out their tongues to show that they weren't the reincarnation of the cruel King, proving they didn't have black tongues

A Sign of Peace:

• 🤝 Today, this gesture is used to demonstrate that the person has no evil thoughts or bad intentions toward the guest
• 🏔️ It is often accompanied by placing the palms together in front of the chest as a complete sign of courtesy

The Aurora Borealis (North) and Aurora Australis (South) are breathtaking light displays created by the sun's interaction with Earth's atmosphere.

The Process:

• ☀️ The sun sends out a stream of charged particles known as "solar wind."
• 🌍 When these particles hit Earth’s magnetic field, they are channeled toward the poles and collide with gases like oxygen and nitrogen.

The Colors:

• 💚 Green is the most common color, produced by oxygen molecules about 60 miles up.
• ❤️ Rare red auroras are produced by oxygen at much higher altitudes, while nitrogen produces blue or purplish-red lights.
