An international team of astronomers has detected a galaxy that is 30 billion light years away.
The galaxy was found using the Hubble Space Telescope and then later confirmed through the Keck Observatory in Hawaii. At 13. 1 billion years old the galaxy\'s distance in light years is much greater than its age due to the expansion of the universe.

It's quite far away then!!
If light travels at the speed of light then how does a telescope see something that far away when the light takes 30 billion years to get to the lense?
Could someone explain it (in layman's terms) because I'm finding it difficult to take in....

What is the velocity of the expansion of the universe, and has the center of the universe been located using red/blue shift measurements?
The entire universe is expanding. There is no center.
In fact, the idea of a center would be counter to the concept of relativity in that it would give us a reference point that was immobile and thus we would be able to measure all velocities against it - allowing the existence of absolute velocity.
If such a concept were true, then relativity experiments would not reveal what they have revealed.
Regarding the expansion velocity, there is none.
There is a rate of expansion. How "fast" an object appears to recede from us depends on how much expanding space exists between that object and ourselves.
People are thinking about this wrong. The AGE of the universe is 13.798 ± 0.037 billion years. This is not the same as the diameter of the observable universe (what we can see from earth) due to the expansion of space, which we now know is accelerating.
The diameter of the observable universe is estimated at 93 billion light years, making it roughly 46-47 billion years in each direction that we look.

Perhaps this Galaxy is where the "Gods" reside. There are bound to be Earth Like Planets Google of years old and in that time frame a Civilization should of developed and traveled here if they don't blow them selves up first like we eventually will.
