You know, stars burn hydrogen by smashing atoms together and releasing the energy. Light particles called photons are emitted and they shoot off in all directions. That's the only reason we can see stars: those photons reach us and our eyes and our telescopes detect them.
That means that whenever I look at a star, the photons entering my eyes have travelled billions and billions of miles to be with me. For thousands of years those light particles have zipped across the universe to end their journey by being absorbed by me, processed into a signal and triggering my brain into appreciating a twinkling image of their origin.
As you know, I often go on about being an astronomer who longs to be an astronaut, so stars have a special place with me. And this lovely connection between me and a distant dream inspired some poetry...
Starlit Lullaby
Through polished glass
And copper bright
He watches on the velvet night
Where tiny points
Of distant light
Come streaming from above
In frozen air
With cloudy eye
He scans across the starry sky
Where planets spin
And comets fly,
His heart to find its love:
Beyond the clouds
Behind the sun
One star is bright and free
And I am chosen by the one
Who lit that star for me
Then floating through
The galaxies
Came all the usual memories
A name he whispered on the breeze
One summer long ago
She'd fallen fast
She'd fallen fair
With silver cheek and gold-spun hair
And love had fallen
To their care
As he alone would know
With polished glass
And copper bright
He stands there almost every night
And in his heart the firelight
Still flickers as he burns
In frozen air
With cloudy eye
He searches out the diamond sky
To sing her starlit lullaby
And hope like stars will twinkle by
Until his love returns
Beyond the clouds
Behind the sun
One star is bright and free
And I am chosen by the one
Who lit that star for me
