Astronomer's may have found the first stars created after the "Big Bang"

I read this news article and way amazed with the technology behind the discovery of what some scientists are postulating may be the first stars created after the "big bang". Here is a quote from the news item, Distant light puzzles scientists:

Fresh evidence of the first objects to emerge after the Big Bang has left scientists debating what they could be.

Researchers say the cosmic glow could be the first stars or quasars, but are not sure which.

Dr. Alexander Kashlinsky and colleagues at the NASA Goddard Space Flight Center will report their findings in the January issue of The Astrophysical Journal.

Using NASA's Spitzer Space Telescope, the researchers analyzed infrared radiation from deep space.

They first removed the bright signal of recent galaxies in the foreground to detect the ancient background glow.

The researchers saw clumps in this infrared background radiation they believe come from the first objects to emerge from the Big Bang.

The way I understand the how this telescope works is through the use an analogy. If you have ever used a high end computer graphics program such as GIMP or Photoshop you will be familiar with the term layers. A photogragh can be built up using several layers. If I want to take two or more photographs containing family members not in both photos I could cut out family members from one photo and insert them into the other. The family members are inserted into the photo using layers. By using layers it is possible to make it appear as if the photo was originally taken with all the family members present. Each family member is added to the photograph using a seperate layer.

Some time later, if the photo is saved in the native format of GIMP or Photoshop, any of the family members not original to the photo can be removed by deleting its layer and thus return the photo to its original state.

I don't understand all the technology behind this very complex telescope. Astronomers have learned how to slice up the telescope's image into "layers" with the ability to be turned off at will. By turning off selected layers allows other elements in the image to become visible. This is an amazing technology.

My eye was drawn to this news item because I have always had a fascination with time travel. I enjoy movies and TV shows using time travel. This news story is a story about astronomers looking back in time. It has taken millions of meleniums for the light to travel the distance from the events of the big bang to us. By the time By the time the light reaches the earth the events have been over for a vey long time. These very faint photons of light we view through the telescope are a windon into the past. In this case they are a window into the bignnings of our universe.
