Hi, Could you solve a puzzle for me? If the speed of light is 299,792.488km per second. Why is that when I look through a telescope and I can see another galaxies within a very short time as it is 25,000 light years away.

Hi Richard,
If you’re looking at something 25,000 light years ago, the light that’s hitting your telescope must be 25,000 years old. As long as the stars were shining back then, you should be able to see them.
Some astronomers think that the ‘Pillars of Creation’ gas cloud was destroyed 6000 years by a nearby exploding star. But since the Pillars are 7000 light years away, we can still see them!
