Red Giant

We learned last time that our sun is a Yellow Dwarf
and that it will burn for 10 billion years!

But what happens after that 10 billion years?
Well that's a long long way in the future, but once a Yellow Dwarf star burns up
it grows larger and becomes a Red Giant.

The closest Red Giant star to us is Gamma Crucis, it is 88 light years away.
Let's look at it's star measurements:
stellar classification: M3.5 (red)
luminosity class: III (giant)

So we can call it M3.5 III, or a red giant.

Red giants can be 4,000 degrees and 100 times larger than our Sun!
They usually last about 1 billion years.

Diode

We've now learned about Doping Semiconductors, and how mixing some chemicals into
a semiconductor can turn it into a conductor.

Doped semiconductors can be used to make something called a diode.

A diode is something that you can put electricity through, but it only goes in one direction.
Kind of like pouring water down hill, it can't flow back up.

If you look on a circuit board you will see all sorts of diodes.
They are a very important part of how things like computers work!

Duck Billed Platypus

We just learned a little about Squirrels.

When scientists first discovered the platypus and tried to tell
other people about it, everyone thought they were joking!

No one thought there could really be an animal with fur and a tail like a beaver's tail,
and also a bill, webbed feet and lays eggs like a duck!

Another interesting thing about the platypus is that they have a small claw (also called a spur)
on their back foot that is poisonous!

Gluteus maximus

Let's keep learning about the muscles in the human body!

Last time we learned about the rectus abdominis

Next up is the gluteal muscles.
The muscles on your back side (or your butt) are called your gluteal muscles.
There are three muscles there, the gluteus minimus, gluteus medius and gluteus maximus.

Sometimes people call those muscles glutes or just talk about the gluteus maximus
since it's the biggest of the three muscles.

You use those muscles when you lift your leg up and down,
or bend your body backwards.

Ukraine

We just learned about the Netherlands.

Let's keep learning about the countries in Europe!

The largest country in Europe by size is the Ukraine.

A popular type of food in the Ukraine is Borscht!

Other Prophets

We just learned about Shadrach, Meshach and Abednego.

God called on many people to be prophets for him through the years.

We've learned about the ones who wrote some of the big books of the bible,
Daniel, Ezekiel, Jeremiah and Isaiah.

They are called the major prophets because they wrote the longest books of prophecy.

There are 12 other prophets called minor prophets not because they weren't important,
but because the books they wrote just weren't as long.

Hosea, Joel, Amos, Obadiah, Jonah, Micah,
Nahum, Habakkuk, Zephaniah, Haggai, Zechariah and Malachi
all delivered prophecies from God to his people.

Some of them warned of the coming exile, some cautioned people to listen to God after the exile,
and some told about the future when Jesus would come along.
