In what is an important addition to the Cute Animals Watching Television canon, a video of a pair of kittens transfixed by a women's tennis match has made its way to YouTube.

The kittens, hanging out on a scratching post, appear to be hanging on every stroke in the match, punctuated by what sounds like No. 1-ranked Victoria Azarenka's signature shrieks.

Unlike some of her opponents, the kittens seem to be unfazed by the noise.

Because the camera is fixed on the felines, it's unclear which match they are watching—setting the video apart from other pet-channel-surfing clips. In the video below, for example, a 3-month-old golden retriever is videotaped while watching "Air Buddies," a 2006 film about five golden retriever pups that set out to rescue their kidnapped parents.

That video has been viewed more than 4.5 million times on YouTube:

Someone alert Ziggy Stardust, there appear to be spiders on Mars.

Strange black objects seen from 200 miles above the surface of Mars are generating interest and speculation that the unidentified objects could be anything from geysers to sunbathing colonies of microorganisms.

NPR presents several photos of the objects, including one taken by the Mars Reconnaissance Orbiter on Jan. 27, 2010, that appears to show "little black flecks dotting the ridges, mostly on the sunny side, like sunbathing spiders sitting in rows."

The objects were first spotted in 1998. Interestingly, they appear when the surface of Mars begins to warm, showing up in the same location most of the time. And then when the Martian winter approaches, they disappear with the same precise regularity. The images have been brought into greater detail by Michael Benson in his book "Planetfall: New Solar System Visions."

Most scientists, including teams from the U.S. Geological Survey, Hungary and the European Space Agency,
