Science Deniers Are Freaking Out About “Cosmos”

Chris Mooney writers at Mother Jones:

Denying evolution: Sunday’s episode of Cosmos was all about evolution. It closely followed the rhetorical strategy of Charles Darwin’s world-changing 1859 book, On the Origin of Species, beginning with an example of “artificial selection” by breeders (Darwin used pigeons, Cosmos used domestic dogs) to get us ready to appreciate the far vaster power of natural selection. It employed Darwin’s favorite metaphor: the “tree of life,” an analogy that helps us see how all organisms are living on different branches of the same hereditary tree. In the episode, Tyson also refuted one of the creationist’s favorite canards: the idea that complex organs, like the eye, could not have been produced through evolution.

Curiosity Rover Watches Mars’ Two Moons Pass Each Other in the Night Sky

Adam Mann writes at Wired:

Unlike our nice round moon, Mars has two lumpy potato-shaped satellites, named for twin Greek gods who personified fear (Phobos) and terror (Deimos). Phobos is the larger and closer moon to Mars, with an average radius of 11 kilometers. Its companion, Deimos, is seven times less massive and three times farther away from Mars, which is why it appears so much smaller. Both bodies are quite tiny as far as moons go — each is about twice the size of Mount Everest. In fact, Phobos and Deimos are so small and have such weak gravity that going more than 25 mph on their surfaces could launch you into space.
