The Astro Alphabet
By Ethan Siege

A is for Aurora, the Earth’s polar lights,
as the Sun’s hot electrons help color our nights.

B is for Black Hole, a star’s collapsed heart,
if you cross its horizon, you’ll never depart.

C is for Comet, with tails, ice, and dust,
a trip near the Sun makes skywatching a must!

D is for Dark Matter, the great cosmic glue
that holds clusters together, but not me and you!

E is for Eclipse, where the Moon, Earth and Sun
cast light-blocking shadows that can’t be outrun.

F is for Fusion, that powers the stars,
as nuclei join, their released light is ours!

G is for Galaxies, in groups and alone,
house billions of planets with lifeforms unknown.

H is for Hubble, for whom Earth’s no place;
a telescope like this belongs up in space.

I is for Ions, making nebulae glow;
as they find electrons, we capture the show.

J is for Jets, from a galaxy’s core,
if you feed them right, they’ll be active once more!

K is for Kepler, whose great laws of motion
keep planets on course in the great cosmic ocean.

L is for Libration, which makes our Moon rock,
it’s a trick of the orbit; it’s tidally locked!

M is for Meteors, which come in a shower,
if skies are just right, you’ll see hundreds an hour!

N is for Nebula, what forms when stars die,
this recycled fuel makes cosmic apple pie.

O is for Opaque, why the Milky Way’s dark,
these cosmic dust lanes make starlight appear stark!

P is for Pulsar, a spinning neutron star,
as the orbits tick by, we know just when we are.

Q is for Quasar, a great radio source,
accelerating matter with little remorse.

R is for Rings, all gas giants possess them,
even one found in another sun’s system!

S is for Spacetime, which curves due to matter,
this Universe-fabric can bend but won’t shatter!

T is for Tides, caused by gravity’s tune,
our oceans bulge out from the Sun and the Moon.

U is the Universe, our goal’s understanding,
with billions of galaxies, as spacetime’s expanding!

V is for Virgo, our nearest great cluster,
with thousands of galaxies, it’s a gut-buster!

W is for Wavelength, the energies of light,
that tell us what atoms are in stars just from sight!

X is for X-rays, high-energy light,
where bursts of new stars show an ionized might.

Y is the Year, where we orbit our Sun,
each planet’s is different; the Earth’s is just one.

Z is for Zenith, so gaze up at the sky!
The Universe is here; let’s learn what, how and why.

WE NEED TO TALK ABOUT THIS SCENE

OK, so this scene wasn’t originally scripted. RTD added it into the script based on Bernard Cribbins’ experience of the war.

Bernard Cribbins fought in World War Two

Bernard Cribbins never killed a man

And Bernard Cribbins is incredibly proud of that. 

AND IN THAT MOMENT I LOVED WILFRED MOTT’S CHARACTER EVEN MORE

NASA finds most Earth-like planet yet

Using the Kepler space telescope, NASA astronomers have found the first planet that they believe to be made of rock, roughly equivalent in size to Earth and potentially capable of supporting life.

The planet, Kepler-186f, orbits the star Kepler-186 some 490 light years away in the constellation Cygnus. It has a diameter of 8,700 miles, making it larger than Earth, and its orbit lies within the “Goldilocks zone” where temperatures could allow for liquid water to flow on its surface. Kepler-186f likely even boasts similar gravity. It’s the first such planet to ever be discovered outside of our solar system.

Luke, you’re all I’ve really got. Everything else, it’s all meaningless, all of it.
Makes no sense without you.
