Presentation Transcript

  1. Life in the Solar System 4 December 2018

  2. Solar system formation

  3. Protoplanets form in the protoplanetary disk

  4. Density waves

  5. Stellar wind blows away the gas and dust: Life arises on Earth soon after

  6. Insight Mars lander

  7. The Instrument Deployment Camera (IDC), located on the robotic arm of NASA's InSight lander, took this picture of the Martian surface on Nov. 26, 2018, the same day the spacecraft touched down on the Red Planet. The camera's transparent dust cover is still on in this image, to prevent particulates kicked up during landing from settling on the camera's lens. This image was relayed from InSight to Earth via NASA's Odyssey spacecraft, currently orbiting Mars. Image Credit: NASA/JPL-Caltech

  8. Insight’s Sandbox

  9. Summary • Life arose early on Earth • Mars meteorite shows biology might have moved between planets • If we found life elsewhere, it might not be like life as we know it • Best candidates: Mars, Europa, Enceladus, Titan • Find the right place to search, look for present and fossil life, bring back smples, compare to Earth life
