What an idea.........

  1. 1. 11/15/99 Norm Herr (sample file)
  2. 2. 11/15/99 Norm Herr (sample file) LIFE ON JUPITER
  3. 3. SOLAR SYSTEM <ul><li>The Sun </li></ul>11/15/99 Norm Herr (sample file) <ul><li>Nine Planets </li></ul><ul><li>Sixty-one satellites of the planets </li></ul><ul><li>Many Comets and asteroids </li></ul>
  4. 5. SUN <ul><li>75% hydrogen and 25% helium by mass </li></ul><ul><li>Sun converts hydrogen to helium in its core </li></ul><ul><li>Differential rotation </li></ul><ul><ul><li>equator the surface rotates once every 25.4 days </li></ul></ul><ul><ul><li>near the poles it's as much as 36 days </li></ul></ul><ul><li>Core conditions </li></ul><ul><ul><li>temperature is 15.6 million Kelvin </li></ul></ul><ul><ul><li>pressure is 250 billion atmospheres </li></ul></ul>11/15/99 Norm Herr (sample file)
  5. 6. EARTH <ul><li>3rd from the Sun </li></ul><ul><li>Moon is 1/6 mass of earth </li></ul><ul><li>period of rotation: 24 hours </li></ul><ul><li>period of orbit 365.25 days </li></ul>11/15/99 Norm Herr (sample file)
  6. 7. Jovian planets <ul><li>There are four jovian planets. </li></ul><ul><li>- Massive, lower in density, composed mostly of H, He and H compounds (water, methane, ammonia) </li></ul><ul><li>Outer layers contain clouds of gaseous H, He and H compounds. Deeper the pressure increases and H and He are in liquid form </li></ul><ul><li>They have cores of rocks, metals and H compounds in very different phases from those we know. </li></ul>
  7. 8. JUPITER <ul><li>Jupiter contains over 70% of the mass in the solar system outside the Sun. </li></ul><ul><li>It is about 11 times the radius and 330 times the mass of the earth. </li></ul><ul><li>It is the first representative of the outer solar system. </li></ul><ul><li>Unlike the inner planets, Jupiter is not a solid body, but instead is a ball of gas and liquid (mostly hydrogen and helium). </li></ul>11/15/99 Norm Herr (sample file)
  8. 9. Jupiter Storms and lightning on Jupiter = energy for life?
  9. 10. POSSIBILITY OF LIFE: JUPITER In 1953, the Miller–Urey experiment demonstrated that a combination of lightning and the chemical compounds that existed in the atmosphere of a primordial Earth could form organic compounds (including amino acids ) that could serve as the building blocks of life. The simulated atmosphere included water, methane, ammonia and molecular hydrogen; all molecules still found in the atmosphere of Jupiter. However, the atmosphere of Jupiter has a strong vertical air circulation, which would carry these compounds down into the lower regions. 11/15/99 Norm Herr (sample file)
  10. 11. The Miller-Urey experiment Miller and Urey                                     -Miller-Urey tested the conditions for creating life in which there was an   - Atmosphere above warmed sea water that contained H 2 O, H 2 , CH 4 , and NH 3 and   - Electrodes that simulated lightning.   - From this setup, they obtained organic compounds such as amino acids that were collected in cooled water.  
  11. 12. THE END THANK YOU 11/15/99 Norm Herr (sample file)
