Not sure what happened to the last thread about this...Anyways!
Here's NASA's astronomy picture of the day...
It's an image of the Soul nebula which is an active region of star formation in in the constellation Cassiopeia. It's about 7500lys away and spans just over 100ly from end to end. Just to put that in perspective that's over 588 trillion miles! The fastest spacecraft (New Horizon) we have ever launched exceeded speeds of 36,300mph (without gravitational assistance). Therefor to travel from the left side of this image to the right in the fastest vehicle we have today under its own power, it would take over 16 billion years!
We are merely a speck amongst the cosmos.
