Space.com's editors present a reading list for space and sci-fi lovers, as well as children who are interested in astronomy and spaceflight.
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. Learn more about interstellar travel and technology.
Launching an interstellar probe sounds exceedingly lofty, ambitious, and tough to do. But there's no need to wait for new technology, say advocates.
The community ponders about the most important questions in space exploration and interrogates dark matter.
Space is big — really big. And if you want to successfully navigate the interstellar depths of our galaxy, you're going to need some sort of reliable system.
The first people to colonize a world in another star system may have trouble describing their new home to the folks back on Earth, a recent study suggests.
Sending scientific instruments to the edge of the heliosphere, or the sun's region of influence, is like going to the edge of the fish bowl.
'Oumuamua is long gone, but it's still leaving scientists guessing. A new explanation proposes that the strange object was a "monstrous fluffy dust aggregate" produced by a busted-up comet.
The proposed "Interstellar Probe" mission would aim to reach 90 billion miles (145 billion kilometers) from the sun, pushing the limits of engineering know-how and space technology.
A search for radio signals coming from 'Oumuamua, the mysterious visitor from afar that zoomed through the inner solar system last fall, came up empty, a new study reports.
Going, going — nope, it's still just going, NASA says of its Voyager 2 probe, which the agency realized was approaching the edge of the solar system back in early October.
Ever since astronomers first spotted their first-ever object from beyond our solar system, it has offered more questions than answers — what is it? Where did it come from? Why is it so darn weird?
Another interstellar asteroid has been spotted in our solar system — and this one is not a visitor but a long-term resident, a new study reports.
A pair of astronomers has mapped the 3D structure of an interstellar cloud in a surprising way: They watched it "sing" with magnetic vibrations.
