Elevation - A shaded relief map, generated with data from the Mars Orbiter Laser Altimeter (MOLA) on NASA's Mars Global Surveyor spacecraft. This map is color-coded by altitude, so you can use the color key at the lower left to estimate elevations.
Visible - A mosaic of images taken by the Mars Orbiter Camera (MOC) on NASA's Mars Global Surveyor spacecraft. MOC is like the digital camera you have at home. Basically, this is what your eyes would see if you were in orbit around Mars.
 

Each week, millions of users around the world search for health information online. As you might expect, there are more flu-related searches during flu season, more allergy-related searches during allergy season, and more sunburn-related searches during the summer. You can explore all of these phenomena using Google Insights for Search. But can search query trends provide the basis for an accurate, reliable model of real-world phenomena?

We have found a close relationship between how many people search for flu-related topics and how many people actually have flu symptoms. Our results have been published in the journal Nature.
 

Traveling to the stars has never been easier.  Using Google Maps this tool provides an exciting way to browse and explore the universe. You can find the positions of the planets and constellations on the sky and even watching the birth of distant galaxies as seen by the Hubble Space Telescope. We are particularly excited about the ability to view the universe at different wavelengths, to see how it would look if our eyes worked in the x-rays or infrared. As you explore these new layers, play with the transparency to blend between the different wavelengths and see how different parts of the universe light up at different wavelengths
If you are interested in what's happening on the sky tonight or over the next few months then check out the podcasts from Earth and Sky or search for the position of your favorite planet.
