Once upon a time in space,
There were particles that filled every place,
Protons were one of them, tiny and small,
But with a mighty force, they held atoms in thrall.

Relativity was a theory that made them all think,
About time and space, and how they could link,
To understand the universe, so vast and wide,
And the mysteries it held deep inside.

Redshift showed us that galaxies move away,
From each other, in a grand cosmic display,
Pulsars spin with a rhythm so true,
And their light shines bright, like a beacon through.

Photometry measures the light that we see,
And helps us learn about stars and their energy,
A singularity is a point of infinite mass,
Where gravity is strong, and time slows as if in a pass.

Radius is the distance from center to edge,
And it tells us how big a star is, like a measuring wedge,
Parallax helps us measure the distance to stars,
And how far they are from us, even if they're far.

Photons are particles of light that we can't see,
But they travel through space, endlessly and free,
Quasars are like beacons, far away and bright,
And they help us understand the universe's light.

Radian is a unit we use to measure angles,
And it helps us study the universe's tangles,
With all these words and concepts so grand,
We can explore space and what's out there in the land.

Reflections

1. What is your favorite scientific concept or term that you learned about in the story?
2. Can you name a celestial object that was mentioned in the story and explain what makes it unique?
3. What are some ways that scientists study the universe and gather information about its properties?
4. If you could travel to any place in space, where would you go and why?
5. How do you think learning about space and its mysteries can help us better understand our own planet and life on Earth?
