Exploring Saturn: A Look at Its Rings, Atmosphere, and Internal Structure

DESCRIPTION

Discover the wonders of Saturn, the second-largest planet in our Solar System. With its stunning rings spanning 200,000 km yet just 0.2 km thick, Saturn showcases icy particles and intriguing features like gaps and shepherding satellites. Despite receiving only 25% of the sunlight that Jupiter does, Saturn emits more heat, likely due to gravitational contraction and unique atmospheric processes. Delve into Saturn’s magnetic field, dynamic yellowish-tan clouds, and similarities to Jupiter, as we explore this magnificent "Ring World."

Presentation Transcript

  1. Saturn from HST

  2. Saturn from Voyager

  3. Oblateness of Saturn

  4. Saturn Highlights • Magnetic field about 2/3 of Earth’s • Atmosphere and interior structure similar to Jupiter • Yellowish-tan clouds and fewer dynamic storms • Rings are splendoriforous!

  5. Saturn’s Magnetosphere

  6. Multi-Wavelength Saturn

  7. Saturnian Atmosphere

  8. Interior of Saturn

  9. Sat. receives on 25% as much sunlight as Jup. Yet, Sat. emits 50% more than what it absorbs! Similar to Jup., but for same reason? No! Heat from gravitational contraction should now be gone, since Sat. is smaller Instead, He may be draining thru metallic H mantle to the core, thereby liberating heat In hotter Jup., He remains dissolved – no draining Consequence: He depleted in Sat. atm. – explains why He/H = 1/4 for Jup. but 1/7 for Sat. Internal Heat of Saturn

  10. Artsy “Ring World”

  11. The Rings of Saturn • Rings are 200,000 km across, but less than 0.2 km thick! • Consist mostly of icy particles, ranging in size from 1 cm to 10 m • Rings reside inside the Roche Limit • Main features: • Gaps • Sharp edges • Spokes • Shepherding satellites

  12. Saturn’s Rings

  13. Enceladus Above the Rings

  14. Spokes on the Rings

  15. Rings of the Gas Giants
