Since the image displays the galaxy as it existed 13.3 billion years ago, it provides an unprecedented view into the beginnings of our universe as the big bang is theorized to have happened about 13.7 billion years ago. The image of MACS0647-JD represents an environment when the universe was just 420 million years old.
NASA said that it used the Hubble and Spitzer telescopes as well as "natural zoom lenses" to acquire the image.
The organization noted that 8 billion years after MACS0647-JD light had begun its journey, "it took a detour along multiple paths around the massive galaxy cluster MACS J0647+7015." The cluster served as magnification source for the light source:
"Because of gravitational lensing, the […] research team was able to observe three magnified images of MACS0647-JD with the Hubble telescope," NASA said. "The cluster's gravity boosted the light from the faraway galaxy, making the images appear about eight, seven, and two times brighter than they otherwise would that enabled astronomers to detect the galaxy more efficiently and with greater confidence."
NASA estimates that MACS0647-JD is less than 600 light years wide, which compares to 150,000 light years of the Milky Way.
MACS0647-JD WAS just a fraction of the size of the Milky Way and is believed to have beenbe 13.3 billion light years away.
Fixed! By the time the light reached us this galaxy was already long gone - as was reported in the rest of the article.
I am sure you know better than all the scientists in the world based on some very rough guess work and five seconds of googling.
The reason why you are not right is because the "edge" of the universe, if there is one, is not like the surface of a sphere in which we reside. We are also NOT at the center of the universe. The universe expands about every point uniformly, so while it appears that everything is moving away from us, it looks like that from every other part of the universe as well. See this picture (http://en.wikipedia.org/wiki/File:Expansion_of_Space_%28Galaxies%29.png) and the corresponding wiki page for some clarification.
Albeit I have hardly touched on some ideas that your questions purport to explain, you can be well assured that thousands of cosmologists, astronomers, and other physicists haven't just made a simple arithmetic error (as you've suggested) when talking about the expansion of the universe.
So how exactly NASA took a picture from a time where there were no cameras in existence,
when it is still hard to take a still picture from a moving object today.
Even out own suns light takes about 8 minutes to reach the earth.
