The Milky Way

The Milky Way

A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. When you look up at stars in the night sky, you're seeing other stars in the Milky Way.

What Is a Galaxy? | NASA Space Place – NASA Science for Kids

is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.

How long is 1 light-year in Earth years?

Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles.

How long would it take to travel 10,000 light-years?

Ten thousand times 6E12 equals 6E16. So the distance is 60,000 trillion miles. If a human runs at a speed of six miles per hour, it will take him/her 10,000 trillion hours to complete the journey. This span of time is equal to 1.142 trillion years.

How far away is 1 lightyear in miles?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

How long would it take to travel 1500 light-years?

4. It takes light 1500 years to travel from earth to the star, but the astronaut makes the trip in 15 years.

Light seconds, light years, light centuries: How to measure extreme distances - Yuan-Sen Ting

Will humans ever travel 1 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.

How long would it take to travel 500 light years?

The light travels at the speed of 1 light year. Therefore, if we assume light to be travelling, then it will travel 500 light years in 500 years.

How long would it take to travel 1,000 light years?

To do so, you will need a speed of almost the speed of light, so in the reference frame of Earth, you will have spent just a tad more that 1000 yr to travel 1000 ly. i.e. 1000 years, 4 hours, and 23 minutes in Earth's reference frame.

How many light years is the Milky Way?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across.

How long would it take us to travel 4 light years?

Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations. Indeed, most of the humans involved would never see Earth or its exoplanet counterpart.

How long would it take to travel 100 trillion light years?

Some galaxies will have fallen over the cosmic horizon, where no amount of time would ever let you reach them. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years.

How far back in time can we see?

We can see light from 13.8 billion years ago, although it is not star light – there were no stars then. The furthest light we can see is the cosmic microwave background (CMB), which is the light left over from the Big Bang, forming at just 380,000 years after our cosmic birth.

Do you age in light years?

Re: How would you age at the speed of light

The simple answer is, anything moving through space at c, equal to the speed of light in a vacuum, experiences zero time flow. If you were to travel at the speed of light, you would experience no time.

How long would it take us to travel a light-year?

Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.

How many light years can we go?

The light that travels the longest gets stretched by the greatest amount, and the object that emitted that light is now at a greater distance because the universe is expanding. We can see objects up to 46.1 billion light-years away precisely because of the expanding universe.

How far can we see in space?

So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do.

Can we travel 600 light years?

Since one light year is the equivalent nearly six trillion miles, it would take 22 million years to travel 600 light years on a space shuttle and visit Kepler 22-b with our current technology.

Will we ever travel the speed of light?

In 1947 humans first surpassed the (much slower) speed of sound, paving the way for the commercial Concorde jet and other supersonic aircraft. 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.

How long will it take to exit the Milky Way?

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

Can we travel faster than light-years?

Within conventional physics, in accordance with Albert Einstein's theories of relativity, there's no real way to reach or exceed the speed of light, which is something we'd need for any journey measured in light-years.

How many light-years away is the farthest?

Earendel is extremely far away from earth – 28 billion light-years away, to be exact. To see Earendel, scientists needed to rely on a magnifying glass of sorts, known as gravitational lensing.

How far is the black hole from Earth?

An international group of astronomers recently announced the discovery of the black hole, which sits about 1,600 light years from Earth. A light year is the distance light travels in one year. In space, light moves about 9.4 trillion kilometers each year. The researchers named the black hole Gaia BH1.

How fast is a light-year in mph?

Light travels at a constant speed of 670,616,629 mph which means that light covers a speed of 670 million miles in an hour. Light travels a distance of 5.88 trillion miles in one Earth year, according to NASA.

How fast speed of light is?

Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).
