Lightbulb 8 minutes for light to reach us from the SUN

so if a God covered it with a big screen we would not notice for 8 mins after

Light takes 2 hours 50 mins to get to us from Uranus

The light travel time between Melbourne and London is only 0.05 seconds

The nearest large galaxy to the Milky Way is the Andromeda Galaxy. it ies about 2 1/2 million light years from Earth. The light we see from it tonight left it more than 2 million years ago.


GN-z11 is a high-redshift galaxy found in the constellation Ursa Major. light from this galaxy takes 13.4 BILLION years to get to us



Having a galaxy with a billion stars present just 400 million years after the Big Bang is astonishing.

So we are actually seeing this galaxy as it was 400 million years after the big bang. To see how it looks now we would have to wait 13.4 billion years.
