March 27 - April 5, 2025
Speaker: Dr. Dana Backman, SETI Institute Astronomy Activation Ambassadors Program

Topics:

• Astrophysics & Planetary Science in Antarctica
  How does Antarctica relate to space? From collecting Moon and Mars meteorites on the ice surface to making sensitive measurements of cosmological background radiation, hear some of the incredible astronomical discoveries made on the seventh continent.
• Snowball Earth
  There is evidence that at least three times in the distant past, Earth went through “snowball” episodes in which miles-thick ice extended from the poles to the equator, aka “Ice Ages on steroids”. We’ll look at the evidence for, and possible causes of, those episodes.
• Good planets gone bad
  Available evidence indicates that surface conditions on Venus, Earth, and Mars were once quite similar, including the presence of liquid water on all three planets. What happened? Explore the effects of global climate changes extending over billions of years on these sibling worlds.
