My First aglow with borrowed light,
My Second is a ship’s dimension,
My Whole, as seen to dance by night
Au clair de lune, defies detention.
The more moisture there is in the sky, the more the light from the sun, moon, and stars is dimmed or reddened. A very clear sky permits more starlight to penetrate, thus the stars appear brighter. Moisture tends to hold in the day’s heat like a blanket. The less moisture there is in the air at night, the more the temperature tends to fall. Thus, the brighter the stars appear, the cooler is the night.
The halo that sometimes surrounds the moon is a beautiful sight. The halo is caused by light that is refracted as it passes through ice crystals of high-level clouds.While these high-level clouds themselves don’t carry any precipitation, they often foretell an advancing system of low pressure, which tends to bring undesirable weather conditions. While rain or snow may not always follow, the appearance of a halo provides a higher probability of wet weather.

The harvest moon has come,
Booming softly through heaven, like a bassoon.
And the earth replies all night, like a deep drum.
Our star the sun is a big ball of gas
and it’s 99 percent of our solar’s systems mass
It’s an average star in our Milky Way
Warming the Earth every day.
What powers our Sun and makes it so bright?
Come on and tell me, what makes all that light?
Hans Bethe long ago reached the conclusion
it changes Hydrogen to Helium by nuclear fusion.
When fusion takes place
Light is created and it makes its way out (although rather belated)
through the Photosphere, that’s the part that we see,
The light comes out and shines on you and me. Oooohhh.
About a million Earths could fit in the sun,
but if you were there you wouldn’t have much fun.
It’s six thousand degrees at the photosphere
and much hotter inside the solar atmosphere.
There are a few places where
it’s not so hot, like at the center of a big sunspot.
But heat is relative, it’s still pretty warm
sitting on a sun spot would do you great harm.
Galileo discovered sunspots.
What are those things, those funny dots?
They’re cooler parts, scientists feel,
caused by a stronger magnetic field.
The spots move around the
the face of the Sun, proving to all…… solar rotation!
A strange kind of movement, to do a full roll,
25 days in the middle, 36 at the poles.
What about flares?
I’ve hard of them here.
They’re like giant explosions in the Chromosphere.
The magnetic fields above those sunspots, reconnecting
again after being in knots.
Above the Chromosphere the Corona is placed,
it’s millions of degrees and reaches way into space.
It’s very thin, but read my lips,
that’s the part that you see in a solar eclipse.
That’s the end of our song about Mr. Sun.
We hope that you find that learning is fun,
but never look at the Sun you could go blind,
just keep on enjoying that warm sunshine.
There was a young lady named Bright,
Who traveled much faster than light.
She started one day
In the relative way,
And returned on the previous night
