Yuri Milner and astrophysicist Stephen Hawking announced Breakthrough Starshot, a new space exploration initiative, on April 12, 2016, in New York City.
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.

Is time travel possible? Are the past and future set or can they be changed? Sci-fi books and films have long explored these ideas.
Matt Damon, star of the new movie "The Martian," has appeared in two other major science fiction movies in the last two years. Could the Hollywood A-lister keep up his science fiction streak?
Blasting tiny, waferlike sailing spacecraft with powerful lasers could slash interstellar flight times from thousands of years to mere decades, one researcher says.
To broaden support for space exploration, advocates should consider approaching religious groups – especially in settings that are familiar to that religion, a new study suggests.
Borg-like assimilation may not be an interstellar reality, but having a resilient software system is essential to ensure your starship can cope with any scenario in the depths of space.
Astrophysicist Kip Thorne's book on black holes was a revelation for me in college, both for its science content and Thorne's willingness to engage the public.
The two big space movies of 2014 — "The Theory of Everything" and "Interstellar" — have both been nominated for five Academy Awards.
