Question:
What is the farthest space object from the Earth?



Replies:
The farthest objects that we can see are some very bright galaxies that are shining at us almost from the beginning of the universe. These are called "quasars" because they look like very small objects (quasi-stellar) even though they are so bright. Depending on how old the universe is, these galaxies are around 10 billion light-years away. We also have signals almost from the beginning of the universe. The problem with space is the distances are so huge that the most distant things were there a very long time ago - it is impossible for us to be able to see instantaneously what is out there at 10 billion light-years, but light takes 10 billion years to get there!
