One of the most interesting topic,I came across.
The universe is still under construction.Mass present in universe is utilized and takes forms and shapes of stars,planets etc.The images we received are ''old images'' of stars.
For example, if NASA receives image of juvenile star,it means that star is no longer in that condition,might be in dying phase..and the reason behind which our satellites are capturing old images,means that photons emitted by juvenile star have traveled long distance and it has finally interacted with satellite cameras.Meanwhile on the other hand,that juvenile star has crossed such phase.Also note that times passes slowly in universe,yet still we attain old images.
More investigation is needed in this regard,who knows that at far away distances,might be somewhere in the universe,new environment for species have been established,already?
