The light, or in this case actually ultraviolet radiation, has nothing substantial in between us and the target galaxy to block or absorb the radiation that was emitted, so basically that radiation traveled for 4 billion years from there to here and we simply 'see' it, the same as the light you see from the stars in the sky.

The light from the Sun we 'see' in the same manner, but its emissions only take minutes to get here.

To: All

Whenever life gets you down Mrs. Brown
And things seem hard or tough
And people are stupid, obnoxious or daft
And you feel that you've had quite enough...

Just, remember that you're standing on a planet that’s evolving
And revolving at nine hundred miles an hour
It’s orbiting at nineteen miles a second, so it’s reckoned
A sun that is the source of all our power

The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm at forty thousand miles an hour
Of the galaxy we call the Milky Way

Our galaxy itself, contains a hundred billion stars
It’s a hundred thousand light years side-to-side
It bulges in the middle, sixteen thousand light years thick
But out by us it just three thousand light years wide

We're thirty thousand light years from galactic central point
We go round every two hundred million years
And our galaxy is only one of millions of billions in this amazing and
expanding universe

The universe itself keeps on expanding and expanding
In all of the directions it can whiz
As fast as it can go, the speed of light you know
Twelve million miles a minute and that’s the fastest speed there is
So remember when you’re feeling very small and insecure
How amazingly unlikely is your birth
And pray that there’s intelligent life somewhere up in space
Cause there’s bugger-all down here on Earth
