Could we see a galaxy that is 25 billion light-years away?
-No, because a galaxy could not possibly be that far away. No, because it would be beyond the bounds of our observable universe. -three-fourths of the age of the universe. -two billion years less than the age of the universe.
How long would it take to travel from one end of the Milky Way to the other?
The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.
How many light-years does it take to cross the Milky Way?
Past studies have suggested the Milky Way is between 100,000 light-years and 160,000 light-years across. (One light-year is the distance light travels in a year, about 6 trillion miles or 10 trillion kilometers.)
Could we see a galaxy that is 20 billion light-years away?
Average distances between galaxies are increasing with time. Could we see a galaxy that is 20 billion light-years away? (Assume that we mean a “lookback time” of 20 billion years.) No, because it would be beyond the bounds of our observable universe.
How far is Earth in light-years?
approximately 6 trillion miles
A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers).
How long would it take to travel 93 billion light-years?
How many years it takes light to travel x distance. It would take light 93 billion years to go 93 billion light years. But the universe will expand more during that time. The visible part of the universe is 93 ly in diameter.
How long would it take to travel 25000 light years?
The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world.
How long would it take to go 500 light years?
500 light years is equal to 3,162,053,8 astronomical units and needs to fly 8,783,483 years. Depends on the restrictions … Voyager 1 is managing 17-odd kmps, that’s pretty fast for an extra-solar-system vehicle. At that speed the trek 500ly would be 8750000years.
How long would it take to travel 13.3 billion light years?
To travel 13.3 billion light years from Earth, Voyager 1 would then take 228,900 years to do so.
How long would it take to travel 93 billion light years?
How many light years away is the Andromeda Galaxy?
With the advent of modern telescopes and science, the Andromeda Galaxy is now known to be some 2.5 million light years from us. Think of that for just a moment – the light that you see from this massive galaxy left the stars of Andromeda 2.5 million years ago and got here in October of 2020.
Do you know where we live in the Milky Way galaxy?
By now I am sure that you know that we live in an amazing galaxy known as the Milky Way. Some 105,000 light years from side to side, with well over 200 billion stars. We are located only 27,000 light years from the galactic center and go around the center once in some 225 million years – quite amazing stuff!
How many light-years across is the Milky Way?
Past studies have suggested the Milky Way is between 100,000 light-years and 160,000 light-years across. (One light-year is the distance light travels in a year, about 6 trillion miles or 10 trillion kilometers.) To put the find in perspective with the location of our own sun,…
How far away is our Solar System from the Earth?
Our Solar System is about 25,000 light years away from the center of our galaxy – we live in the suburbs of our galaxy. Just as the Earth goes around the Sun, the Sun goes around the center of the Milky Way.
