Mars: Periglacial morphology and ice stability

This talk focuses on studies of University Valley as a Mars analog for periglacial morphology and ice stability. Dr. Heldmann discusses observations revealing a unique trend as the depth to ice-cemented ground varies linearly from near zero at the head of the valley to over 80 cm deep 1.5 km away at the valley mouth.

  • We often hear fantastic scientific claims that would change everything if true. We examine news stories that seem too sensational to be valid, yet just might be, such as whether a killer asteroid has Earth’s name on it. Plus, a journalist investigates why people hold on to beliefs even when the evidence is stacked hard against them – from skepticism about climate change to Holocaust denial.

  • Elisa Quintana discusses the methods of combining ground-based observations with transit modeling to confirm the Kepler-186f system, and presents her team's theoretical studies on the formation and habitability of this planet. They also present updates on several promising multi-planet systems that have Earth-sized, and possibly sub-Earth-sized, candidates in the habitable zones of cool low-mass stars in the Kepler field-of-view.

  • There is an ongoing drama in the Saturnian ring system that causes small moons to be born and then destroyed on time scales that are but an eyeblink in the history of the solar system. SETI Institute scientists Robert French and Mark Showalter have examined photos made by NASA’s Cassini spacecraft of Saturn’s F ring, and compared them to 30 year-old pictures made by the Voyager mission. They think they understand why the photos seem so different: There is a never-ending process that both produces and destroys small moons.

  • The discovery of the Higgs boson at the CERN Large Hadron Collider poses new challenges to our understanding of basic quantum physics. We appear to live in a universe that is slightly unstable and will eventually decay catastrophically.

  • Hard though it may be to believe, SETI Institute scientist Adrian Brown has worked out a scheme for finding particles ten times smaller than the width of a human hair, even at many light-years distance. They can do this by observing a blue tint in the light from far-off objects.

Communicate New Worlds of Discovery

What we know about our universe is changing all the time. New discoveries are happening more now than at any time in our history as humans. 

We know that you want to see the inner workings of the research that's done at our facilites and our scientists want to share their work with you as it happens. For as little as $20 per month, you'll get more access to the SETI Institute and The Carl Sagan center than ever before. Plus right now, as a donor you'll get some of the great perks with our Communicate campaign - Like T-Shirts and window clings to show your friends that you care about discovery and exploration.

Benefits of membership include:

  • Membership card and SETI Institute lapel pin
  • Explorer magazine (digital version)
  • Invitations to special events
  • Join now and we'll send you the exclusive "Communicate" window cling.
