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

https://en.wikipedia.org/wiki/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

In fact, the Voyager 1 probe has already ventured beyond the borders of the solar system, reaching interstellar space in August 2012. Nonetheless, even travelling fast enough to reach Jupiter two years after its launch in 1977, it would still take some 80,000 years to reach the nearest star beyond the Sun, if it were on a direct course.

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

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.

Humanity's great leap into the space between the stars has, in a sense, already begun. NASA's Voyager 1 probe broke through the sun's magnetic bubble to touch the interstellar wind. Voyager 2 isn't far behind. New Horizons shot past Pluto on its way to encounters with more distant dwarf worlds, the rubble at the solar system's edge.

On the Sun Spot, we have been exploring the various instruments on Voyager 2 one at a time, and analyzing how scientists read the individual sets of data sent to Earth from the far-reaching spacecraft.But one instrument we have not yet talked about is Voyager 2's Magnetometer, or MAG for short. During the Voyagers' first planetary mission, the MAG was designed to investigate the

The Voyager interstellar mission extends the exploration of the solar system beyond the neighborhood of the outer planets to the outer limits of the Sun's sphere of influence, and possibly beyond. ...

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

It took about 400 days for such solar outbursts to reach interstellar space, leading to an estimated distance of 117 to 177 AU (117 to 177 times the distance from the sun to the Earth) to the heliopause. They knew, though, that they would be able to observe plasma oscillations directly once Voyager 1 was surrounded by interstellar plasma.

We measure distances in interstellar space in light years, the distance that light travels in one year—about 9.46 trillion kilometres. Even our closest stellar neighbour, Proxima Centauri, is 4.24 light years away. Current propulsion technology would take thousands of years to cover these vast distances.

To accelerate the spacecraft to the speed required for interstellar travel, an Earth-based phased array of lasers (a light beamer) can be used. The output of the light beamer would need to be around 100 gigawatts to reach sufficiently fast speeds of 0.2-0.3c [2]. Lasers with petawatt-level outputs have already been created, so creating a 100

This conceptual spacecraft would be parked in near interstellar space to use our sun as a gigantic lens, allowing zoomed-in close-ups of planets orbiting other stars. A space telescope would be lofted to a position far beyond Pluto, some 550 times the distance from Earth to the sun, or farther.
