asked:


How does the photography in space works? I understand the concept of light speed, that it takes time for the image to arrive? But does that mean the image travels in the light? For instance, in 1995 the Hubble telescope took a photo of the part of the Eagle Nebula but that part of it was destroyed 6000 before! Can someone specify then the process?
Does the image that reaches the Hubble telescope that takes a photo of it, actually travels within the light itself? And THATS whats causing the delay? Because the light itself takes time to reach?

I’m an astronomy teacher looking to create a evening observation session component for my class. However I don’t have many ideas on what kind of things I can do with telescopes. Perhaps someone took a course in telescopes or know of a place where I can find info about this.

Summer time asked:


When they say “They are so far away that the VLT sees them just 750 million to a billion years after the Big Bang.”

Are they talking about the telescopes ability to see billions of km’s into the space or are they talking about the light surrounding the star and it’s ability to travel? Or something else? Explain to me in a very simple way … I’m finding it tough to make a mental picture of this whole idea.
