  • Chris McKay: Tracking Down Aliens
    Chris McKay, a planetary scientist at the Ames Research Center, has long been investigating the coldest and driest places on Earth. These harsh environments - and the ability of life to adapt there - could point the way to finding life on Mars. McKay presented this lecture, entitled "Drilling in Permafrost on Mars to Search for a Second Genesis of Life," at a NASA Astrobiology Institute Director's Seminar on November 29, 2004.

  • Jack Farmer: Deciphering Mars
    Dr. Jack Farmer of Arizona State University is an astrobiologist whose attention is often focused on Mars. Farmer is a longtime member of a community of scientists working to understand both the geologic history of Mars and the planet's potential to support life. At the recent Earth System Processes II conference, Farmer gave a talk on the current state of understanding about Mars: what we know and what we'd like to know.

  • Jaymie Matthews: The Humble Space Telescope
    By combining results from the Hubble Telescope in visible light and the Chandra Telescope in x-rays, astronomers have plotted the evolution of galaxies. From 13.7 billion years ago, a decided birth rate boom and bust cycle is observable. The model is called 'bottom-up': smaller galaxies and cluster collide and merge to make bigger ones.
