Will we ever reach another galaxy?

Intergalactic distances are roughly a hundred-thousandfold (five orders of magnitude) greater than their interstellar counterparts. The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction.

How long would it take to reach another galaxy?

Travel Time

To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager's speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!

Will humans survive Andromeda collision?

Q. Will humans survive the Andromeda collision? A: There is a 1 in 400,000 chance that humans will survive the Andromeda collision.

How long would it take Voyager 1 to reach Andromeda?

... and even if we ignored that - it would need 3.3 billion years for the journey at the current distance. And that's just 3,299,999,980 years after the power supply ran out.

How many years would it take to get out of the galaxy?

Even traveling at the speed of light, it would take nearly a hundred thousand years!

Will We Ever Visit Other Stars?

Have we ever left our galaxy?

No spacecraft has gone farther than NASA's Voyager 1. Launched in 1977 to fly by Jupiter and Saturn, Voyager 1 crossed into interstellar space in August 2012 and continues to collect data.

Will humans ever leave the solar system?

So, while Earth will eventually leave the solar system one way or another, it's not something we will have to worry about for a few billion years yet.

How has Voyager 1 not hit anything?

The asteroid belt between Mars and Jupiter contains millions of asteroids, but a space probe has never had to worry about hitting into one on its way to the outer planets. The reason for this is because space is so big and so empty when it comes to macroscopic objects such as planets and asteroids.

What is the lifespan of Voyager 1?

The original life expectancy of both spacecraft was five years. Within that time, both had encountered Jupiter and Saturn, returning stunning findings of active volcanoes and lightning beyond Earth, new moons around Jupiter and Saturn, a thick atmosphere on the moon Titan, and more.

Can life exist in Andromeda galaxy?

Can the Andromeda Galaxy support life? Since we can't yet say for certain whether there are any other stars in our own galaxy that host life, it is even harder to say whether there might be life, or at least the conditions for life, in another galaxy.

How long will humans last?

Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.

Is there something huge lurking behind the Milky Way?

Astronomers have detected an enormous extragalactic structure hiding in an uncharted region of space far beyond the Milky Way's center. This phantom region, known as the zone of avoidance, is a blank spot on our map of the universe, comprising somewhere between 10% and 20% of the night sky.

What is the next habitable planet?

Proxima Centauri b (or Proxima b), sometimes referred to as Alpha Centauri Cb, is an exoplanet orbiting within the habitable zone of the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of the larger triple star system Alpha Centauri.

Will humans ever travel at the speed of light?

Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.

Can we leave the Milky Way?

So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre. We'd need to go much further to escape the 'halo' of diffuse gas, old stars and globular clusters that surrounds the Milky Way's stellar disk.

Will Voyager 1 eventually stop?

The two Voyager spacecraft could remain in the range of the Deep Space Network through about 2036, depending on how much power the spacecraft still have to transmit a signal back to Earth.

Can we still talk to Voyager 2?

Because of Voyager 2's trajectory relative to Earth, it can talk to only one station and one antenna in the network: Canberra's 70 meter dish, also known as DSS 43. And that dish will need to be improved for the new Mars missions, prompting a shutdown and temporary dismantlement.

Why did NASA shut down Voyager 1?

NASA is shutting down systems of the Voyager probes to save dwindling power. The probes are flagging after 45 years — the move is a way of keeping them going up until 2030. Voyager 1 and 2, launched in 1977, have made it farther than any other object made by humans.

Why did Voyager 1 stop taking pictures?

Not in the Plan

In fact, the Voyager team turned down several requests to take the images because of limited engineering resources and potential danger to the cameras from pointing them close to the Sun.

How long would humans survive without the Sun?

Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after. Within two months, the ocean's surface would freeze over, but it would take another thousand years for our seas to freeze solid.

Can a human travel a light year?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no.
