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 we ever be able to travel to another galaxy?
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. However, theoretically speaking,
there is nothing to conclusively indicate that intergalactic travel is impossible
.
How long does it take to get to the galaxy from Earth?
Travel Time
If Voyager were to travel to the center of our Galaxy, it would take
more than 450,000,000 years
to travel the 8 kpc. If it could travel at the speed of light, an impossibility due to Special Relativity, it would still take over 26,000 years to arrive!
How many years does it take to travel around the galaxy?
Bottom line: The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about
225-250 million years
to revolve once around the galaxy's center. This length of time is called a cosmic year.
How long would it take to get to the moon at the speed of light?
On average, there is about 238,855 miles (384,400 kilometers) of distance between our planet and its large natural satellite. This means all moonlight we see is 1.255 seconds old, and a round-trip between the Earth and moon at light speed takes about
2.51 seconds
.
Will Voyager 1 leave the Milky Way?
How far can we go in space?
That
~18 billion light-year
figure is the limit of the reachable Universe, set by the expansion of the Universe and the effects of dark energy.
Is intergalactic space empty?
The space between stars is known as interstellar space, and so the space between galaxies is called intergalactic space. These are the
vast empty spaces that sit between galaxies
.
Did star Trek ever leave the galaxy?
For all the boldly going where no one has gone before, leaving the galaxy is pretty uncommon within the various narratives of Trek. And yet,
in the second TOS pilot, “Where No Man Has Gone Before,” the Enterprise left the galaxy.
How long until the universe ends?
22 billion years
in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.
How far is the nearest black hole from Earth?
In 2020, a team of astronomers with the European Southern Observatory (ESO) discovered the closest black hole to Earth in the HR 6819 system, just
1,000 light-years
away, only to have other scientists dispute the findings.
How close is Earth to the edge of the galaxy?
The Solar System (and Earth) is located about 25,000 light-years to the galactic center and 25,000 light-years away from the rim. So basically, if you were to think of the Milky Way as a big record, we would be the spot that's
roughly halfway between the center and the edge
.
How far away is the oldest galaxy we've ever discovered?
Up until the discovery of HD1 in 2022, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, having a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately
32 billion light-years
(9.8 billion parsecs).
How long does it take to get to Mars from Earth?
The total journey time from Earth to Mars takes between
150-300 days
depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target. It really just depends on how much fuel you're willing to burn to get there. More fuel, shorter travel time.
How far is the edge of the universe?
The comoving distance from Earth to the edge of the observable universe is about
14.26 gigaparsecs
(46.5 billion light-years or 4.40×10
26
m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×10
26
m).
How long does light take to reach the Earth from the Sun?
Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes
499.0 seconds
for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.
How fast did Saitama jump from the Moon?
It took Saitama
19 seconds
to reach the earth from the moon (used a stopwatch). As a comparison, it takes light 1.3 seconds. So basically Saitama was travelling at 14.82% the speed of light or 44.46×10^6 m/s.
How long does light from the Moon take to get to Earth?
Light travels at 300,000 kilometres per second, so it takes about
1.3 seconds
for light to travel from the Moon back to the Earth. In other words, the Moon is 1.3 light-seconds away from the Earth.
How far will Voyager 1 be in a billion years?
The Voyagers have enough electrical power and thruster fuel to keep its current suite of science instruments on until at least 2025. By that time, Voyager 1 will be about
13.8 billion miles
(22.1 billion kilometers) from the Sun and Voyager 2 will be 11.4 billion miles (18.4 billion kilometers) away.
How long will it take Voyager to reach Alpha Centauri?
It will take
20,000 years
for our earliest probes to reach Alpha Centauri. Some of the earliest explorations of the universe beyond our solar system were made by four probes launched by NASA in the 1970s — Pioneer 10 and 11 and Voyager 1 and 2.
How much fuel does Voyager 1 have left?
NASA estimates that the Voyagers' fuel efficiency is
upwards of 30,000 miles per gallon of hydrazine
. Voyager 1 has enough hydrazine to keep going until 2040, while Voyager 2's juice can keep it hurtling along until 2034.
How long is 1 hour in space?
One hour on Earth is
0.0026 seconds
in space.
Is the flag still in the moon?
Images taken by a Nasa spacecraft show that
the American flags planted in the Moon's soil by Apollo astronauts are mostly still standing
. The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows – except the one planted during the Apollo 11 mission.
What's the farthest man has Travelled in space?
The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were
400,171 kilometers (248,655 miles)
away from Earth on April 14, 1970. This record has stood untouched for over 50 years!
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that,
at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit)
.
Are there black holes in intergalactic space?
Bubbles of gas released by black holes spread across vast distances of the intergalactic space
, affecting star formation thousands of lightyears away from their source, a new study shows. Astronomers knew that black holes draw in matter from their surroundings due to their powerful gravitational pull.
Are there stars that aren't in galaxies?
Although
stars cannot form in the voids between galaxies
(since the density of matter is far too low), there are in fact large numbers of ‘intergalactic stars'. It has been estimated, for example, that 10 per cent of the mass of the Virgo galaxy cluster is in the form of these stellar interlopers.
