🌟 What is the James Webb Space Telescope?

The James Webb Space Telescope (short name: JWST) is the most powerful space telescope ever built.

It helps scientists see very far into space and learn about:

• Stars ⭐
• Planets 🪐
• Galaxies 🌌
• The early universe

---

🚀 When was it launched?

• Launched on December 25, 2021 🎄
• Sent into space by a rocket
• It does not orbit Earth like Hubble

---

📍 Where is JWST?

• It stays very far from Earth at a place called Lagrange Point 2 (L2)
• This place keeps it:
  • Cold ❄️
  • Stable
  • Away from Earth’s heat and light

---

👀 How is it different from Hubble?

Hubble	James Webb
Sees visible light	Sees infrared light
Smaller mirror	Huge mirror (6.5 m)
Orbits Earth	Stays far in space

🧠 Infrared light helps Webb see through dust and very old objects.

🪞 Big golden mirror

• Webb has 18 golden mirrors
• They work together like one giant mirror
• Gold helps reflect infrared light very well

---

🌌 What can JWST discover?

• First galaxies after the Big Bang
• How stars and planets are born
• Gases in planet atmospheres
• Possible signs of life on distant planets 👽

---

❄️ Why does it need a sunshield?

• Webb has a giant sunshield (like a tennis court!)
• It blocks heat from:
  • The Sun ☀️
  • Earth 🌍
  • The Moon 🌙
• Keeps the telescope super cold so it can see better

---

🧠 Easy to remember

James Webb is a time machine that looks into the past

⭐ Fun facts for kids

• It can see light from 13+ billion years ago
• Its mirror had to unfold in space!
• It helps answer big questions like:
