Interstellar travel is the ability to travel between stars in the exploration of space. In science fiction, interstellar travel is often depicted as faster-than-light, such as warp drive on "Star Trek" or light speed in "Star Wars," but research is underway to build robotic probes for Alpha Centauri (as in the Breakthrough Starshot project), and to develop hibernation systems, generation ships and other long-duration space technology needed to one day send astronauts to other stars.

Christopher Nolan's space epic 'Interstellar' is still a month away from theaters, but the third and final trailer is out now.
The first teaser poster for Christopher Nolan's space epic "Interstellar" launched online Tuesday (May 6), with the clock ticking down toward the film's November 7 premiere.
An interstellar spacecraft could conceivably be powered by the radiation emitted by a tiny, manmade black hole. Here's a look at what it would take to turn this ambitious idea into reality.
Humanity should start thinking about how to interact with alien species long before coming into contact with extraterrestrial life, experts say.
Large payloads are costly come launchtime, but one company is exploring how to throw them into space with technology based on the classical slingshot.
A large enough sail would provide thrust from the pressure of sunlight and, perhaps, laser light beamed from afar, allowing a probe to cover vast distances with no need for fuel.
Experts and space scientists from around the world will descend on Dallas, Tex. tomorrow (Aug. 15) for a summit focused on understanding humanity's ability to travel to distant stars.
Space illustrator Adrian Mann created these concept images of futuristic nuclear-powered interstellar starships.
