Join us in Chaco Canyon to think about what we can learn from watching shadows.
The sun holds an honored place in the lives of Southwestern Native Americans. Hear insights into the importance of the sun from Dr. Shelly Valdez, educator at Laguna Pueblo; Dr. Isabel Hawkins, solar researcher at UC Berkeley; and Andrew Garcia Sr., coordinator of Tewa dancers. Time-lapse footage of light moving across a pictograph at Wijiji 931. Watch as the square of light moves across the wall and niches at Rinconada.
See the movement of shadow on the North/South wall. Astronomers in many parts of the world watched as Venus moved across the disk of the Sun, one of the rarest planetary alignments. The Exploratorium webcast this historic event from Greece. Astronomers in many parts of the world watched as Venus moved across the disk of the Sun, one of the rarest planetary alignments. The Exploratorium webcast this historic event from Greece. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity from a special Valentine's Day secret ingredient. Chris McKay, Planetary Scientist at the NASA Ames Research Center, has traveled the world seeking Mars-like environments. In the Dry Valleys of Antarctica—his favorite Mars analog on Earth—Dr. McKay discovered a kind of algae living inside rocks porous to light and water. He’ll show us some of these rocks and talk about the physical conditions required for life. Jonathan Trent, Astrobiologist, NASA Ames Research Center studies "thermophiles," heat-loving microbes inhabiting places once thought too hostile for life, but analogous to environments that might be found on other planets. He discovered that some of these microbes make a protein that appears to stabilize their cell membranes (and may have applications for nanotechnology).
