When the Sun Goes Dark

When the Sun Goes Dark

by Andrew Fraknoi and Dennis Schatz

This richly illustrated book is a fun way to help young astronomers understand all the excitement during a solar eclipse. The book tells how two curious children and their grandparents re-create eclipses in their living room using a lamp, a tennis ball, two Hula Hoops, and table tennis balls. Later, in the backyard and around the house, the family explores safe ways to view a solar eclipse and ponder phenomena from sunspots to phases of the Moon. Written by the authors of NSTA’s award-winning book Solar Science, When the Sun Goes Dark gives children and adults hands-on techniques for learning the science behind eclipses of the Sun and Moon.

The Farthest

The Farthest – Voyager in Space

THE FARTHEST tells the captivating tales of the people and events behind one of humanity’s greatest achievements in exploration: NASA’s Voyager mission, which celebrates its 40th anniversary this August. The twin spacecraft—each with less computing power than a cell phone—used slingshot trajectories to visit Jupiter, Saturn, Uranus and Neptune. They sent back unprecedented images and data that revolutionized our understanding of the spectacular outer planets and their many peculiar moons.

Still going strong four decades after launch, each spacecraft carries an iconic golden record with greetings, music and images from Earth—a gift for any aliens that might one day find it. Voyager 1, which left our solar system and ushered humanity into the interstellar age in 2012, is the farthest-flung object humans have ever created. A billion years from now, when our sun has flamed out and burned Earth to a cinder, the Voyagers and their golden records will still be sailing on—perhaps the only remaining evidence that humanity ever existed.

The Sun Song

by The Chromatics and NASA

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.

Mărţişor

This is a legend of the Romanian Mărţişor (little March)
And here is a slightly modified version with my kindercat’s illustration: pdf

Once upon a time, the Sun used to take the shape of a young man and descend on Earth to dance among folk people.

A dragon found out about this and followed the Sun on Earth, captured him and confined him in a dungeon in his castle. Suddenly the birds stopped singing and the children could not laugh anymore, but no one dared to confront the dragon.

One day a brave young man set out to find the dungeon and free the Sun. Many people joined in and gave him strength and courage to challenge the mighty dragon.

The journey was long and lasted three seasons: summer, autumn and winter.

At the end of the third season the brave young man could finally reach the castle of the dragon where the Sun was imprisoned. The fight lasted several days until the dragon was defeated. Weakened by his wounds the brave young man however managed to set the Sun free to the joy of those who believed in him.

Nature was alive again, people got back their smile, but the brave young man could not make it through spring. His warm blood was draining from his wounds in the snow. With the snow melting, the snowdrops, harbingers of spring, sprouted from the thawing soil. When the last drop of the brave young man’s blood fell on the pure white snow he died with pride that his life served a noble purpose.

Since then people braid two tassels: one white and one red. Every 1st of March men offer this amulet called Mărţişor to the women they love or friends. The red color symbolizes love for all that is beautiful and also the blood of the brave young man, while white represents purity, good health and the snowdrop, the first flower of spring.
