Space & Universe

Exploring the Cosmos

Learn words about planets, stars, galaxies, and India’s space program!

📖 Let’s Learn Space & Universe!

Space — the final frontier! The universe is unimaginably vast, filled with planets, stars, galaxies, and mysteries. Learning space vocabulary connects your English to Science and helps you understand news about ISRO, NASA, and space exploration!

India’s space program ISRO has achieved amazing things — sending missions to the Moon (Chandrayaan) and Mars (Mangalyaan)! Understanding space vocabulary helps you appreciate these incredible achievements.

💡 The Rule

Space vocabulary includes: Objects (planet, star, moon, asteroid), Systems (solar system, galaxy, universe), Movements (orbit, rotation, revolution), and Exploration (astronaut, satellite, rocket, space station).

🎯 Key Concept

🌍 Planet = large body orbiting a star (Earth, Mars, Jupiter)
Star = ball of hot gas that shines (Sun is our nearest star)
🌌 Galaxy = billions of stars grouped together (Milky Way)
🛰️ Satellite = object orbiting a planet (Moon, or man-made)

📋 Space Categories
