If we aren’t alone in the universe, how would we treat our intergalactic neighbors?

The new movie District 9 considers this question by envisioning a present-day Earth where humans and extraterrestrials coexist, albeit uneasily.

Two decades after a colossal spacecraft has stalled over Johannesburg, South Africa, its passengers—millions of confused, malnourished aliens called “prawns” by disparaging humans—have been ghettoized into a grimy, apartheid-echoing militarized zone known as District 9. Then an evil corporation called Multi-National United decides to relocate them to an even more bantustan-like tent city. The subsequent eviction process touches on a host of legal and ethical issues like: What would earthlings do to ET visitors? Kill them? Conduct medical experiments? Attempt to extract valuable weaponry? All of the above?

To aid in our speculation, Pop Omnivore talked to Seth Shostak, senior astronomer at the nonprofit SETI Institute (Search for Extraterrestrial Intelligence) and author of the new book Confessions of an Alien Hunter: A Scientist’s Search for Extraterrestrial Intelligence.

The new movie Moon is a sci-fi throwback—a simple, hermetic story of isolation, identity, and (in)sanity.

In a matter of minutes, the 2001-indebted scene is set: It’s the near future, and a guy named Sam Bell (played by Sam Rockwell) is toiling alone in a mining station on the moon, where he harvests a clean-energy substance called Helium-3 to power a depleted Earth. His only company is a HAL-like robot called GERTY (voiced by Kevin Spacey). His only goal is to play out the last two weeks of his three-year contract.

Even though the film is set in the future, some things about the space station look familiar to children of the television age. When Sam gets a haircut, GERTY uses a gadget that looks a lot like a Flowbee.

In zero gravity, astronauts crave earthly comforts. That’s why they strap their heads to foam “pillows” at night. Alas, liquids pool or slosh and must be ingested from a pouch via straw. “You feel like an insect sucking juices out of another insect,” says astronaut Don Pettit. So, on a mission last November, he made a cup from a plastic sheet sealed with tape.
