πŸ“š Quick Study Guide

    πŸ”­
  • Nebulae are vast clouds of gas and dust in space.
  • 🌟
  • Star formation occurs when gravity causes dense regions within a nebula to collapse.
  • πŸͺ
  • Protoplanetary disks, swirling disks of gas and dust, form around young stars and are where planets are born.
  • 🌌
  • Emission nebulae glow due to ionized gas, often hydrogen, energized by nearby stars.
  • ✨
  • Reflection nebulae shine by reflecting the light of nearby stars.
  • πŸŒ‘
  • Dark nebulae block light from objects behind them.
