PHOTOS: Satellites take artistic views of Earth

The accompanying images were taken by NASA satellites and a joint NASA/U.S. Geological Survey satellite, which orbits about 440 miles above Earth collecting data that are used to study changes in land cover, forest growth, water resources and the atmosphere.

Irrigation systems near Garden City, Kansas: Light colors are harvested fields; red are still growing.

The satellites' instruments can take in a much broader range of light than is visible to the human eye; some of the images were made using infrared, red and blue wavelengths that bring out details in the terrain.

Rare rock and ice are bright red in this image of eastern Russia's dormant Anyuyskiy volcano.

The Empty Quarter, in the southern part of the Arabian Peninsula, is a huge sand desert.

Lake Disappointment, amid sand dunes in western Australia, has salty deposits that look white.

Seventy-five of the images — which span the globe and cover a wide range of terrain — are collected in "Earth As Art," (NASA, $44); they are also available free as an iPad app or an ebook.

  • Cats outsmart the researchers

    I knew a lot had been written about dogs, and I assumed there must be at least a handful of studies on cats. But after weeks of scouring the scientific world for someone - anyone - who studied how cats think, all I was left with was this statement, laughed over the phone to me by one of the world's top animal cognition experts, a Hungarian scientist named Ádám Miklósi.

Now researchers from the University of Colorado Boulder have added another option to the list: genetics.

  • Smartphone kill switches are coming

    Smartphones need kill switches. It's a relatively easy solution to the pricey (and irritating) problem of smartphone theft. But who would have thought that the big carriers would team up with Apple, Google, Microsoft, Nokia, Samsung and lots of other manufacturers to voluntarily begin adding the technology by July 2015? The cooperative spirit! It makes so much sense!
