To anticipate a question that might follow closely from this, there is no way to get around this delay and see what's there "now". The reasons go far beyond this question, but in short, due to relativistic time dilation and length contraction, there's actually no way to define a universal "now", and any mechanism for transmitting information faster than light would also allow for transmitting information backwards in time.

As we know light has a *definite speed* i.e. $c=299792458$ m/s so it takes some **big** time to travel from distant galaxies, right? So I always wonder about the big telescopes and big space companies captured the photos of very distant galaxies. Are they as they were many generations ago or they are fresh (means we see what happened at the time of capture)

When I look at my clock (which is 3 metres from my chair) I see how it was about 10 nanoseconds ago. I don't see the clock "now", but always a little time in the past.

When you look at the sun, you see how it looked 8½ minutes ago.

When you look at GN-z11 you see how it looked 13.4 billion years ago.

That is a fundamental fact about our universe. You can never see anything as they are "now" you can only see how they were at some point in the past. The picture depicts an older time. This is true of every single picture ever taken! But with galaxies, this is very useful. We can see how the typical galaxy has changed over the history of the universe.

(Kashikawa-san is wrong in a couple of ways. It has taken light 13.4 billion years to travel from GN-z11 to Earth.
