I can't seem to leave some news stories alone...
How Far Can You See?
The answer to that question often asked by children seems to be about 2.5-million light years.
That's about 14,686,504,184,000,000,000 miles. Just so you understand, from the Earth to the moon is about 250,000 miles. From the Earth to the sun is about 92,955,807 miles.
So, you can see a long way.
But remember that the faint light you are seeing from M31 is actually the total light output of an entire galaxy. That's a lot of energy.
It takes that much to make the trip to us as something we can see with the naked eye.
