247 = 247*60 light second = 14 820 *299,792,458meters = 4.44292423 × 1012 meters
It means it has taken light 130 years to travel the distance. Light travels 5,878,630,000,000 miles in 1 year, so something 130 light years away, is a LONG way away.
An object that is 8,000 light years away from Earth will take 8,000 years to reach us if it travels at the speed of light. Since nothing can travel faster than light according to our current understanding of physics, this distance would require that same amount of time, 8,000 years, for light (or anything traveling at that speed) to cover the distance to Earth.
That depends on how far away the star is. If the exploding star is 1,000 light years away we would see the supernova 1,000 years later. If it is 2,000 light years away we would see it 2,000 years later.
It doesn't make much sense to talk about something being 52 light-years away from a galaxy: A typical galaxy has a diameter of about 100,000 light-years, and doesn't have a clearly-defined border. Distances between galaxies are hundreds of thousands, or millions, of light-years.It doesn't make much sense to talk about something being 52 light-years away from a galaxy: A typical galaxy has a diameter of about 100,000 light-years, and doesn't have a clearly-defined border.

If you had a telescope on a planet 3000 light years away and zoomed in on Earth, you would see the Earth as it was 3000 years ago. Due to the time it takes for light to travel, you would not be seeing Earth in real-time, but rather how it appeared 3000 years in the past.
No, 'years' is a measure of time and 'light years' is a measure of distance.
A light year - is the distance a pulse of light would travel in an earth 'year'. This equates to a distance of5,869,713,600,000 mile in a single year. Something 10,000 light years from earth would be at a distance of58,697,136,000,000,000 miles - or roughly 58,697 BILLION miles away!
Well the answer is in the question. A light year is the distance it takes light to travel in one year. If something is a 100 light years away, then it will take light ..........
It means it has taken light 130 years to travel the distance. Light travels 5,878,630,000,000 miles in 1 year, so something 130 light years away, is a LONG way away.
Depends on what "something" is. If the "something" was light or an electromagnetic pulse, then it would travel at the speed of light. It the object had mass, then it would not travel at the speed of light. This was a major error in the film 2012 Supernova, where they had time to react to a supernova explosion. In reality, news of the event would occur at the same time the devastation occurred.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 light-years away from Earth.
An object that is 8,000 light years away from Earth will take 8,000 years to reach us if it travels at the speed of light. Since nothing can travel faster than light according to our current understanding of physics, this distance would require that same amount of time, 8,000 years, for light (or anything traveling at that speed) to cover the distance to Earth.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
That depends on how far away the star is. If the exploding star is 1,000 light years away we would see the supernova 1,000 years later. If it is 2,000 light years away we would see it 2,000 years later.

The duration of Light Years Away is 1.75 hours.
