Caltech, JPL, Northrop Grumman to Celebrate 50 Years of Space Exploration

Jill Perry
Before October 1957, space flight was a thing of fantasy. Today we are experienced space explorers with unlimited voyages to undertake. Where is space flight's next horizon? What constitutes sensible space investment? How did the space pioneers accomplish their goals? These topics will be addressed at "50 Years in Space: An International Aerospace Conference Celebrating 50 Years of Space Technology," which will take place from September 19 to 21 at the California Institute of Technology.

Some Earth-like Worlds May Have Foliage of Colors Other Than Green, Researchers Say

Robert Tindol
In the next decade, when scientists are able to study Earth-sized worlds around other stars, they may find that foliage on some of the planets is predominantly yellow—or orange, or red. It all depends on the color of the star the planet orbits and the stuff that makes up the planet's atmosphere.

Caltech's Planet Hunter Mike Brown Wins Annual Feynman Prize for Teaching

Robert Tindol

On a campus where scientific research can be pretty challenging for the uninitiated, Mike Brown's search for new bodies in the outer solar system is as refreshingly straightforward as, well, the brightly colored marble spheres that sit on his shelf. Each sphere represents a Kuiper-belt object he has found in the last few years, including Eris, which led to the demotion of Pluto to the status of "dwarf planet."
