5-day Vacation: August 27, 2011, 2nd Day (part 2)

Today I'll write about the lecture that I have heard. It's not the exact words because I only jot down words that for me is important.
Do you know the movie "horton hears a who?"
We are like the people that lived on that tiny speck.


I will mention 4 stars:
1. Sun
The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. It has a diameter of about 1,392,000 km, about 109 times that of Earth, and its mass (about 2×10³⁰ kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System. Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. Less than 2% consists of heavier elements, including oxygen, carbon, neon, iron, and others.

If the sun has a size of a beach ball, the moon would have a size of a golfball and the earth will have a size of a dot.


2. Betelgeuse

Classified as a red supergiant, Betelgeuse is one of the largest and most luminous stars known. If it were at the center of our Solar System, its surface would extend past the asteroid belt possibly to the orbit of Jupiter and beyond, wholly engulfing Mercury, Venus, Earth and Mars. However, with distance estimates in the last century that have ranged anywhere from 180 to 1,300 light years from Earth, calculating its diameter, luminosity and mass have proven difficult. Betelgeuse is currently thought to lie around 640 light years away, yielding a mean absolute magnitude of about −6.05.

If the Earth has the size of a golf ball, Betelgeuse would have a size of 2 Golden Gate Bridges (end to end) or 4 San Juanico Bridges (end to end).


3. Mu Cephei
Mu Cephei (μ Cep, μ Cephei), also known as Herschel's Garnet Star, is a red supergiant star in the constellation Cepheus. It is one of the largest and most luminous stars known in the Milky Way. It appears garnet red and is given the spectral class of M2Ia.

If the earth has the size of a golfball, Mu Cephei would have a size of 6 Empire state building.


4. Canis Majoris
VY Canis Majoris (VY CMa) is currently the largest known star and also one of the most luminous. Located in the constellation Canis Major, it is a red hypergiant, between 1800 and 2100 solar radii, 8.4–9.8 astronomical units in radius, 3.063 billion km or 1.7 billion miles in diameter, and about 1.5 kiloparsecs (4,900 light years, 4.6×10¹⁶ km or 2.9×10¹⁶ mi) distant from Earth. Unlike most hypergiant stars, which occur in either binary or multiple star systems, VY CMa is a single star.

If the earth has the size of a golfball, Canis Majoris would have a size of Mt. Everest.

You'll find these interesting...
Whirlpool Galaxy
Astronomers loved to study this because its visible (through a telescope syempre)
And you know what else is interesting?
Astronomers found a black hole in it and the black hole has a cross in it.

Do you know what is laminin?
laminin is used to hold things.
A molecular biologist found out that our cells has a laminin that is shape like a cross for it to hold on to.

Colossians 1:17

King James Version (KJV)

 ¹⁷And he is before all things, and by him all things consist.


⁶But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man that thou visitest him?

Romans 11:36

King James Version (KJV)

 ³⁶For of him, and through him, and to him, are all things: to whom be glory for ever. Amen
