The truth is that interstellar travel and exploration is technically possible. There's no law of physics that outright forbids it. But that doesn't necessarily make it easy, and it certainly doesn ...
Interstellar Travel Could Be Possible Even Without Spaceships
The author of a new research article in the International Journal of Astrobiology says that ETCs may not need starships to escape existential threats and travel to another star system. They could instead use free-floating planets, also known as rogue planets. The article is "Migrating extraterrestrial civilizations and interstellar colonization ...
Interstellar travel
Interstellar travel is the hypothetical travel of spacecraft from one star system, solitary star, or planetary system to another. Interstellar travel is expected to prove much more difficult than interplanetary spaceflight due to the vast difference in the scale of the involved distances. Whereas the distance between any two planets in the Solar System is less than 55 astronomical units (AU ...
NASA Technologist Talks What's Needed For Interstellar Travel
It's possible that the big new idea that brings interstellar travel closer to reality has already been envisioned by someone, somewhere in the world, says Johnson. But to meet the challenges of ...
Interstellar: Crossing the Cosmic Void
Movies like "Interstellar" and "Passengers" imagine a time when human beings can travel deep into space, but how close are we? ... And it paints one of the most detailed pictures yet of a possible interstellar probe using present-day technology. An annotated illustration of the interstellar medium. The solar gravity lens marks the point where a ...
A new interstellar probe could take NASA deeper into space than ever
Now a team of scientists is hoping to take the next interstellar mission even farther. NASA's twin Voyager spacecraft, launched in 1977, have been traveling for so long that they've left our solar ...
Is Interstellar Travel Really Possible?
NASA's new James Webb Space Telescope (JWST) was recently hit by a micrometeoroid. One of the 18 golden mirror segments on the telescope was hit, causing some minor damage. Discovery.com and astrophysicist Paul M. Sutter tell you everything you need to know about the possibility of interstellar travel.
The Voyage to Interstellar Space
The Voyage to Interstellar Space. By all means, Voyager 1 and Voyager 2 shouldn't even be here. Now in interstellar space, they are pushing the limits of spacecraft and exploration, journeying through the cosmic neighborhood, giving us our first direct look into the space beyond our star. But when they launched in 1977, Voyager 1 and Voyager ...
Interstellar Mission
At the time, it was at a distance of about 122 AU, or about 11 billion miles (18 billion kilometers) from the sun. This kind of interstellar exploration is the ultimate goal of the Voyager Interstellar Mission. Voyager 2, which is traveling in a different direction from Voyager 1, crossed the heliopause into interstellar space on November 5, 2018.
Interstellar travel: From science fiction to reality
"While we know these are physically possible, the technology level needed for interstellar travel seems very far away - perhaps 100 to 200 years in the future." While scientists dream of antimatter propulsion, which could enable space travel at 70 per cent of the speed of light, nuclear fusion propulsion appears much closer to reality.
These New Technologies Could Make Interstellar Travel Real
John Brophy, a flight engineer at JPL, is developing a novel engine that could accelerate space travel by another factor of 10. Leon Alkalai, a JPL mission architect, is plotting a distant journey that would begin with an improbable, Icarus-esque plunge toward the sun. ... The interstellar medium remains poorly understood because we can't get ...
10 Things: Going Interstellar
Here are 10 things we've learned about going interstellar. 1. The Space Between. Interstellar space is often called the space between the stars, but more specifically, it's the region between our Sun's heliosphere and the astrospheres of other stars. Our heliosphere is a vast bubble of plasma - a gas of charged particles - that spews ...
Take an interstellar tour: what would you see if you could travel
As we exit the solar system and enter interstellar space, we will stop initially alongside Pioneer 11, one of the first probes to leave our planetary neighbourhood. There is no "you are leaving ...
Could We Achieve Interstellar Travel Using Only Known Physics?
Although this concept has never led to a successful rocket, it could be the future of interstellar space travel. ECF (Experimental Engine Cold Flow) experimental nuclear rocket engine, NASA, 1967 1.)
Inside the Quest for a Real 'Star Trek' Warp Drive
Still, various teams have proposed ways to at least reach a fraction of light speed and hasten our exploration of interstellar space. Back in 1958, researchers at San Diego-based defense ...
Intergalactic travel
Intergalactic travel is the hypothetical crewed or uncrewed travel between galaxies.Due to the enormous distances between the Milky Way and even its closest neighbors—tens of thousands to millions of light-years—any such venture would be far more technologically and financially demanding than even interstellar travel.Intergalactic distances are roughly a hundred-thousandfold (five orders ...

Interstellar travel: the technology we need to go long-distance
Unfortunately, these may just be pipedreams, which would mean that long-distance interstellar travel is not possible. ... If the speed of light limits how fast you can travel through space, then ...
Voyager 1 was in crisis in interstellar space. NASA wouldn't give up
Far beyond the orbit of Pluto, it is riding point for all humanity as it hurtles through interstellar space. But on Nov. 14, Voyager 1 suddenly stopped sending any data back to Earth.
PDF Is Interstellar Space Travel Possible
light. In principle, interstellar travel may thus appear possible. However, energies involved in such an endeavour would make it next to impossible. In a space ship the fuel needed for the later parts of the journey has to be carried aboard and thus also needs to be accelerated till it is utilized. Therefore the initial mass at the start of
Scientists Just Made a Breakthrough For Light Speed Tech
Warp drive technology is at the stage of 1882 car technology, he says: when automobile travel was possible, but it still looked like a hard, hard problem. The Applied Physics team believes future ...
Wild Discovery Suggests a Warp Drive Is Possible Within ...
And then there's the warp drive, or Alcubierre drive, a hypothetical engine that can create warps in space-time that circumvent the speed limit.It would work by squeezing space in the fore and expanding it aft, like toothpaste in a tube, thus shrinking the amount of space to be traveled and allowing some hypothetical craft to traverse the distance faster than if space-time had been left alone.
NASA is trying to fix Voyager 1, but the old spacecraft's days are
Voyager 1 has been traveling through space since 1977, and some scientists hoped it could keep sending back science data for 50 years. But a serious glitch has put that milestone in jeopardy.
