It has been 20 years since we learned the expansion of the universe is accelerating due to the mysterious force called dark energy. Saul Perlmutter shared the Nobel Prize in Physics because of his contributions. Now he shares his thoughts with us. Also at this year’s COSPAR Assembly in Pasadena was the Director General of China’s National Space Science Center, Wang Chi. Have you played with Eyes on the Solar System? JPL’s Kevin Hussey conceived of the NASA's Eyes app that will take you across the solar system and beyond. And you’ll hear Planetary Society co-founder Carl Sagan’s message to the Martians in our future. That’s right after this week’s What’s Up.

Simulation of the distribution of galaxies
This simulation of the distribution of galaxies across a section of the expanding universe also represents the distribution of dark matter, but reveals little about the nature of dark energy.
