Despite any political differences between the United States and Russia, the space agencies of the two countries continue their cooperative work in Earth's orbit, aboard the International Space Station. Apart from the research being done in microgravity, ISS crew members continue to send back amazing images of our home world, photographed from low Earth orbit. Gathered here are recent images of Earth from aboard the ISS, and from a handful of other NASA satellites.

It's that time of year again when dogs with unusually large heads, hairless bodies and other oddities compete to be the World's Ugliest Dog. This year's winner? A 2-year-old mutt named Peanut, whose wild white and brown hair, bulging eyes and protruding teeth belie his sweet, energetic personality. Peanut's owner, Holly Chandler of Greenville, North Carolina, says he was seriously burned as a puppy and she wants to use her pet to raise awareness about animal abuse. She plans to use the $1,500 prize to pay for other animals' veterinary bills. The contest, held at the Sonoma-Marin Fairgrounds in Petaluma, California, is in its 26 year. The dogs are scored by a three-judge panel in several categories, including special or unusual attributes, personality and natural ugliness.
