How long has it taken light to reach us from these distant galaxies?

Light can take tens of thousands of years or more to reach us from distant parts of our galaxy, which is roughly 100,000 light years wide.

How far is the most distant galaxy?

13.4 billion light-years
“From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years, or 134 nonillion kilometers (that’s 134 followed by 30 zeros),” Kashikawa said in a statement. “But measuring and verifying such a distance is not an easy task.”

How far can the Hubble Space Telescope See?

The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.

How long does it take light to travel 14 billion miles?

NASA’s extraordinarily long-lived Voyager 1 probe this week passed 14 billion miles from Earth. It takes light nearly 21 hours to reach the spacecraft, making commanding the thing increasingly tricky.

How can the Universe be 46 billion light-years?

You might think, in a Universe limited by the speed of light, that would be 13.8 billion light years: the age of the Universe multiplied by the speed of light. In actuality, we can see for 46 billion light years in all directions, for a total diameter of 92 billion light years.

How old was the universe when light from a distant galaxy?

It is true that the universe was only about 500 million years old when the light from this distant galaxy left, given that the light traveled for 13.3 billion years and that the universe is approximately 13.8 billion years old.

Is the distance from us to this galaxy 13 billion light years?

However, it is not true that the distance from us to this galaxy is 13.3 billion light-years — either now or as measured long ago when the light left. To understand why, note that the universe expands even while the light travels toward us.

How long did it take for the light to reach Hubble?

The object’s light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years.

How far back in time can we see the universe?

Therefore, the longer we wait, the farther we can see, as light travels in a straight line at the speed of light. So after 13.8 billion years, you’d expect to be able to see back almost 13.8 billion light years, subtracting only how long it took stars and galaxies to form after the Big Bang.
