SPACE STUDIES
These studies are made to show things like the planets the galaxy and the
life and death of a star.

Usually a star is formed by a substance called nebula. Nebula is a gas that forms a star and makes it shine.
But one of the main things we have to talk about is a supernova . A supernova is a massive explosion of
gas coming from a star that dies.
This is a supernova
Yes we all knew this was coming what's space without the solar system. You might think its just a row of
planet's but there is much more to it than meets the eye. You might not know but mars once had water on
it. Pluto is not a planet but a freezing cold star. The sun does not actually shine directly towards earth the
moon reflects sun rays from the sun to our home planet earth.
Black holes
Black holes are not just holes that are black in space they are much more dangerous. Some
people believe a black hole is a portal to another universe or an alternate dimension. some
people belive that a black hole is a portal
that stretches between time and space itself. But nobody knows because they never lived to tell
the tale apparently the pressure of the black hole rips your spine apart.
NASA are a company that keep track of activity in space. If
it wasn't for NASA’s space technology and scientists we
would not have all our information about space as we have
today. Most of the rocket launches are ordered by NASA.
NASA stands for
Comets
Comets are big balls of rock and ice that travel at light
speed. There is a very special comet called Halies comet
apparently only comes round every 100 years because it is
caught in the suns gravitational field.
The sun
In Greek mythology the sun was called Sol. Sol was the sun god and also the
leader of all gods. The sun actually is not a planet it is a gigantic star. The sun is
the biggest thing in our Solar System. The reason Mercury is so hot is because it
is the closest planet to the sun.
Mercury
Mercury is the closest planet to the sun making it the hottest
planet in the solar system . Seen from earth it appears to
move around its orbit in about 116 days which is much faster
than any other planet. This rapid motion may have led to it
being named after the roman diety Mercury. The fast flying
messenger to the gods. Because it has no atmosphere to
retain heat Mercury's surfaces experience the greatest
temperature variation
Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.[11] It has no natural satellite. It
is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in
the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows.[12] Because Venus
is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a
maximum of 47.8°. Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, for
which reason it has been referred to by ancient cultures as the Morning Star or Evening Star.
Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size,
gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to
Earth). However, it has also been shown to be very different from Earth in other respects. It has the densest
atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric
pressure at the planet's surface is 92 times that of Earth's. With a mean surface temperature of 735 K (462
°C; 863 °F), Venus is by far the hottest planet in the Solar System. It has no carbon cycle to lock carbon
back into rocks and surface features, nor does it seem to have any organic life to absorb it in biomass.
Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from
being seen from space in visible light. Venus may have possessed oceans in the past,[13][14] but these
would have vaporized as the temperature rose due to a runaway greenhouse effect.[15] The water has
most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen
has been swept into interplanetary space by the solar wind.[16] Venus's surface is a dry desertscape
interspersed with slab-like rocks and periodically refreshed by volcanism.
Earth, also known as the world,[26] Terra,[28] or Gaia,[30] is the third
planet from the Sun, the densest planet in the Solar System, the
largest of the Solar System's four terrestrial planets, and the only
celestial body known to accommodate life. It is home to about 8.74
million species.[31][32] There are billions of humans[33] who depend
upon its biosphere and minerals. The Earth's human population is
divided among about two hundred independent states that interact
through diplomacy, conflict, travel, trade, and media.
Solar Eclipse
A solar eclipse is caused when the moon gets in the way of the of the
Sun causing the sun’s rays to be blocked off making them unable to
reach Earth. A solar eclipse however can only last a few minutes.
As seen from the Earth, a solar eclipse is a type of eclipse that
occurs when the Moon passes between the Sun and Earth, and the
Moon fully or partially blocks ("occults") the Sun. This can happen
only at new moon, when the Sun and the Moon are in conjunction as
seen from Earth in an alignment referred to as syzygy. In a total
eclipse, the disk of the Sun is fully obscured by the Moon. In partial
and annular eclipses only part of the Sun is obscured.
Lunar Eclipse
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can
occur only when the Sun, Earth, and Moon are aligned (in "syzygy") exactly, or very closely so, with the
Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. The type and length of
an eclipse depend upon the Moon's location relative to its orbital nodes.
Unlike a solar eclipse, which can only be viewed
from a certain relatively small area of the world, a
lunar eclipse may be viewed from anywhere on the
night side of the Earth. A lunar eclipse lasts for a few
hours, whereas a total solar eclipse lasts for only a
few minutes at any given place, due to the smaller
size of the moon's shadow. Also unlike solar
eclipses, lunar eclipses are safe to view without any
eye protection or special precautions, as they are
dimmer than the full moon. The next lunar eclipse
will occur in 8th of October 2014
