"Amazing fact on Big bang''
*Scientists believe that because
both space and time began
with the Big Bang
There may possibly
be no time
before it occurred.

A star is a ball of gas
so hot that it burns and
glows. The temperature of
stars range from 3,812^o F
to about 90,012^o F.

The Solar System is made up of the Sun
the nine planets and their 135 known moons
asteroids comets dust and gas. The planets asteroids and comets travel around the sun the center of our Solar System.
The sun is the Earth's nearest
star about 93.2 million mi away. It is a medium sized star and belongs to a group of star types that astronomers call main sequence stars. Most of these including the sun will burn for about ten billion years before expanding and cooling to become red giants ultimately using up all their fuel. In addition, The sun is about halfway through its lifetime.
As the tilts on its axis and
spins around the Sun the
Sun warms different parts of the
Earth is the third planet out from the
Sun an average 93 (ninety-three) million mi away.
On January 3 at the nearest point of its orbit collect the perihelion the Earth is
91,402,335 (ninety-one thousand four hundred two thousand three hundred thirty-five) Mi away
from the sun. On July 4th at its furthest the ophelion it is 94,509,440 (ninety-four thousand five hundred nine thousand four hundred forty) mi away.
Astronomers viewing the Sun through special filters can detect dark spots, which is called sunspots on the sun's surface. The sunspots are caused by changes to the magnetic field surrounding the Sun. As the Sun spins round the magnetic field become tangled. Sunspots develop in places where the magnetic force has become up to 3,000 (three thousand) times stranger than so the sunspots appear darker than the surrounding surface.
The Moon is 238,885 (two hundred thirty-eighty thousand eight hundred eighty-five) mi from the Earth and about 25 (twenty-five) percent of Earth's size. In addition, the moon orbits the Earth once every month and each orbit takes 27.3 days It spins once on its oxis every 720 (seven hundred twenty) hours. The Moon is the brightest object in the night sky. But it does not give out any light itself it shines only because its light colored surface reflects sunlight. Only the side the Moon lit by the Sun is bright enough to see. And because we see more of this side each then less again. The moon seems to change shape. During the first half of each monthly cycle the Moon waxes grows from a crescent shaped New Moon its a full moon. During the second half it crescent shaped old moon. The moon may have formed when a smaller newly planet callidad with the Earth early on in the formation of the Solar System.
the Moon part 2
A lunor month is the time between
one Full Moon and the next. This is
slighty longer than the time the moon
takes to orbit the Earth because the
Earth is also moving.
The Moon has no atmophere and its
surface is simply gray dust pitted with
crators created by meteories smoshing
into it early in its history.
On the Moon's surface one large
dark patches called seas because that
is what people once believed they were
They are in fact Java flows from
ancient valconoes.
One side of the Moon is always
turned away from us and is called its
dark sides this is because the moon
spins around on its axis at exactly the
same speed that it orbits the Earth.
The moon is relatively close to the
Earth and therefore seem much
larger than the stars.
The moon's gravity is
17 percent of the Earth's
so astronouts in space suits
can jump 13 ft high.
The changes from New to Full
Moon and back again are called
the phases of the Moon. The full cycle
from New to Full and takes one month.

Blue Sky
The sky looks blue because light from the Sun
is scattered by tiny particles of dust and moisture in the air. This breaks up the tiny sunlight into its rainbow colors. The blue rays scatter most so we see blue more and the sky looks like blue.
