Simple, does not our own star ( the sun ) shine all the time? Those Stars
where shining for many many millions of years. So while we are looking at a
star that's maybe 12 billion lightyears away, we are most likly seeing the
light that it released anytime during it's long lift span.

Can someone help me understand this ?

The powerful telescopes are supposed to see in the past.
OK, I get thet. If you look at a distant star, you catch the light it
emitted one year ago if it is at one light-year distance.
But you cannot see the light it emitted 2 years ago, for that light has
already travelled past you.
Correct ?
Now, some say they can watch light coming from stars created just after
the big bang.
This I cannot understand, because that light should have travelled past
us already, from the original point.

Please explain ...
