The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.

Some stars are so far away will these sources of the light that reaches us will be the same?
Invariably not. Even our own Sun is about 8.3 minutes older than the light we see. So if the Sun suddenly exploded, we would not know for 8.3 minutes. Likewise with the stars. Alpha Centauri A is 4.3 years older than the light we see, whereas Betelgeuse is 640 years older than the light we see. In fact Betelgeuse may have exploded 500 years ago, but we will have to wait another 140 year before we find out. Some stars are so far away, that in all probability, they are no longer there, but we still see the light that they emitted eons ago.
How long does it takes the sunlight to reach the Earth?
It takes light around 8 minutes and 19 seconds to reach the earth from the sun.
How long does it take a beam of light to reach planet earth from your nearest star?
It takes approx. 8 and half minutes to reach earth
Is a star going supernova in the Orion?
It's quite possible that we MAY see Betelgeuse go supernova. It may have already happened but as the star is over 600 light years away, the light will take a while to reach us.
What time light takes from Sun to reach Earth is?
8 minutes.
How long does it take light to reach earth from Betelgeuse?
Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it. But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!
How does it take for light to reach earth?
If you mean light from the Sun, then it takes eight minutes for the light to reach the Earth.
Does most of suns energy reach earth in light energy?
it does reach the earth in light energy.
How does sunlight reach earth?
the light speed are very fast so light easily reach on earth
How long it takes the suns light to reach earth?
It takes approximately 8 minutes for the Sun's light to reach Earth.
What is the length of time it takes for light from stars to reach the earth?
Light travels at (approximately) 300,000 kilometers per second or 186,000 miles per second. The time it takes starlight to reach Earth depends entirely on the distance. The nearest Star (other than the Sun) is the red dwarf Proxima Centauri, at a distance of 4.2 light-years, where one light-year is the distance that light travels in one year. The red giant star Betelgeuse, the red star at the shoulder of the constellation Orion, is about 800 light-years away. The Milky Way galaxy is about 100,000 light-years across.
Does the light of the sun beetlejuice travel faster than earth's sun?
Well, the answer to the question that you asked is yes. Any light will travel faster than the sun travels.But if the question that you meant to ask is "Does the light of the star Betelgeuse travel faster than The Sun's light?" then no.All light travels at the same speed in a vacuum. (about 3*108 m/s) The sun's light takes about 8 minutes to reach us, so when you see the sun, you are actually seeing how it was 8 minutes ago. When you see the star Betelgeuse, you see it how it was 641.8 years ago, because it is 641.8 light years away.
How does the light from the moon reach the earth?
The moon does not emit light, rather it reflects it. The light from the sun shines on the moon, and it is reflected to earth.
How long will it take the get the suns heat to earth?
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
How long will it take earth to get to the sun?
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
How long would it take to get to betelgeuse in a spaceship?
That depends on the speed of the spaceship. If it were traveling at the speed of light, which is the maximum speed that any object can reach, it would take 640 years to get there.
