Hi!
This time I wanna post about SCIENCE. *smile*
Especially about solar system.
We ignore my poems, the beverages, the foods, my life secrets, my peculiar moments, just for while.
So, let's enjoy our journey crossing our space, Milky Way.
Solar system are cluster of planets, moon, and pieces of
space that orbitted on sun’s surrounding. Solar system is made probably from
gas super clouds and interstellar dust that become one part because of that own
gravity about five billion years ago (Lippincott, 2007:36).
There are the planets that walk around the sun on
Milky Way:
"MERCURY"
Mercury is the nearest planet to the sun. Usually it is too
close to the sun to be seen at all with the unaided eye. When it is visible, it’s
low above the western horizon just after sunset or the eastern horizon just
before sunrise. Thus, Mercury is always viewed in either morning or evening
twilight. The brief and and widely separated intervals of time when the planet
can be seen confused the Greek astronomers, who thought that Mercury was two
separate objects. The Greek called the planet “Hermes” when it appeared in the
evening sky and “Apollo” when it appeared in the morning sky (Fix, 2006:208).
I think Mercury's surface dry enough, like no water in it. And the temperature is too hot. Maybe we can be melted easily if we live there.
Mercury has no satellite (Lippincott, 2007:45).

"VENUS"
Like Mercury, Venus is most often seen in the western
sky in the evening or in the eastern sky in the morning. The ancient Greeks
thought that these were different objects, so they called it “Phosporus” when
it appeared in the morning sky and “Hesperus” when it appeared in the evening
sky. Venus is so bright that it sometimes can be seen in the daytime if the sky
is very clear and if an observer knows where to look. Venus has a nearly
uniform yellowish appearance with none of the variations in brightness and
color that can be seen for Mars, Jupiter, and Saturn. The only, features that
can be detected from the Earth are vague, dark blotches that show up in
photographs made using a blue or ultraviolet filter. The Earth’s orbital
distance is closer to that of Venus than any other planet. Despite their
apparent similarity, however, Venus and the Earth are strikingly different in
many important ways. Their atmospheres, for example, have little in common.
Venus’s atmosphere is much hotter and denser than Earth’s and has an entirely
different chemical composition. The types of surface features on the two
planets are quite different as well. The similarity of the Earth and Venus in
mass, radius, and distance from the Sun makes their great differences in
atmosphere and surface features surprising and important. It seems likely that
the Earth and Venus formed and began to evolve along similar paths. However,
relatively small early differences, particularly distance from the Sun, soon
led those paths to diverge drastically. By comparing the Earth and Venus, we
can see how early differences affect the evolution of Earthlike planets (Fix,
2006: 215-216).
Why Venus called the most beautiful planet in the world due to its surface?
Venus has no satellite (Lippincott, 2007:46).

"EARTH"
Earth is the one planet in solar system that can
support the life. Combination of water liquid, atmosphere consists of oxygen
and nitrogen, and dinamic weather pattern giving basic element to various life
distribution of plants and animals. During more than million years, land and
ocean form have changed, the mountains get bigger or slide, and the continent
crosses the Earth. Some scientist see the balance of harmony threatened by
population density. Deforestation and combustion of fossil fuel mean that
carbon dioxide filled atmosphere faster than regenerative cycle plant to
produce oxygen. Because carbon dioxide snares the heat below Earth’s atmosphere
and doesn’t let it out again, Earth temperature can be rise. Earth has a
satellite called Moon (Lippincott: 2007:42).
Yeah, we live in this planet. We should aware to our place, the one and only our place. Actually the Earth is beautiful and cool enough if it's observed from the space, right?
But, why in this planet happened some crime things, like murder?
Or black magic?
And it just makes everything bad. Everyone wanna own everything-greedy.
Pfffttt, yaaa sudah laaaahhh. Ups, back into English.
I think we have to keep the peacefulness anywhere and anytime. *simple*

"MARS"
Whereas Venus excited people's imagination because they could see so little of its surface, Mars was exciting because its surface shown so much. Many of Mars' features seemed to have counterparts on Earth. Clouds can often be seen in Mars' atmosphere, and pattern of dark markings on the surface come and go with the seasons, much like the patterns of changing vegetation on the Earth (Fix, 2006:233).As the twentieth century progressed, the idea of Mars as a habitable planet was gradually discarded. New
observations showed that Mars’s atmosphere is far thinner than that of the
Earth, that carbon dioxide is the principal gas, and that oxygen and water
vapor are essentially absent. Any notion of Mars as an “abode of life” was
shattered when the first Mars probe, Mariner
4, flew past Mars in July 1965. The 22 images it returned showed a heavily
cratered surface, much like that of our Moon. Several hundred images radioed
back to the Earth from the Mariner 6
and 7 fybys in 1969 confirmed the new
picture of Mars as a dead planet. They showed that the atmospheric pressure of
Mars is less than 1% that of the Earth at sea level and that the polar caps are
primarily frozen carbon dioxide (dry ice) rather than water. Mariner 4, 6, and 7 returned pictures of only a small percentage of the total surface
in Mars. In 1971 Mariner 9 went into
orbit around Mars with the mission of imaging the entire surface of the planet.
When Marriner 9 arrived, a dust storm
covered the entire planet. The only visible feature was a cluster of dark
spots. As the dust settled, the spots proved to be immense volcanos with peaks
so high they poked above the surrounding dust. Other pictures showed canyon
systems that dwarfed our Grand Canyon, and widespread channels that looked like
dry riverbeds. Like the earlier Mariner 4
pictures, those from Mariner 9
changed astronomer’s views about Mars. The picture showed that Mars must have a
very interesting, complicated history. Even better pictures of Mars were
returned by the two Viking orbiters
that arrived at Mars in 1976. Each Viking
orbiter was accompanied by a lander that safely touched down on Mars’s surface
and, for several years, returned images of its surroundings, meteorological
data, and seismic measurements. Each lander also carried equipment to examine
the soil of Mars for microbial life. After a gap of almost 20 years, Mars
exploration resumed again in 1997. In July 1997, Pathfinder landed on Mars. Two days after landing, Pathfinder releases Sojourner, a small six-wheeled rover that explored the Martian
surface in the immediate vicinity of Pathfinder.
Sojourner carried a spectrometer to
measure the chemical composition of the soils and rocks around the landing
site. In September 1997, Mars Global
Surveyor went in orbit around Mars with the mission of mapping Mars with
much better resolusion than ever before. Mars
Global Surveyor is able to resolve features on Mars as small as 1.4 m,
about the size of a bicycle. In 2003-2004, a number of missions reached Mars,
including the Spirit and Opportunity rovers (Fix, 2006: 235-236). Mars has two satellites, there are Phobos and Deimos (Lippincott: 2007:49).
We know that Mars called "The Red Planet" because of its color. Red means brave and ill tempered. Is that true? Ahhh, I wish Mars doesn't have this character like on the emoticon below:

"JUPITER"
Jupiter is the most massive planet. In fact, it makes up 70% of all the
planetary matter in the solar system. It is also the largest planet; its
diameter is approximately 11 times as large as the Earth’s and 1/10 as large as
the Sun’s (Fix, 2006: 267). Although the outer layers of Jupiter (and the other
giant planets) consist almost entirely of transparent gas, clouds of liquid and
solid droplets produce a wealth of colored features. Notice that there are
alternating dark belts and light zones lying parallel to its equator. In
addition, numerous bright and dark spots are visible. The largest and most
famous of these is the Great Red Spot,
an immense rotating cloud pattern that has been present at least since its
discovery by Giovanni Cassini in 1665. The colors of Jupiter range from
reddish-pink to blue-gray. Although Jupiter is certainly colorful, its colors
are much more subdued than those of the Earth. Jupiter’s red isn’t as vivid as
an apple and its blue isn’t as bright as a mountain sky (Fix, 2006: 268). Jupiter has 16 satellites, there are Metis, Andraster,
Almathea, Thebe, Io, Europa, Ganymede, Calisto, Leda, Himalia, Lysithea, Elara,
Aananke, Carme, Pasiphea, and Sinopea.
If I see Jupiter, I wanna eat some cakes.

"SATURN"
Saturn was the most distant planet known to the ancients.
When Galileo pointed his new telescope at Saturn, he was perplexed because
Saturn seemed to have ears. Two years later he found that the ears were gone.
He couldn’t explain their disappearance, but guessed that they would soon
return, which they did. What Galileo had seen were the spectacular rings of
Saturn. The rings are very thin and were viewed edge-on at the time Galileo
thought they had vanished. Saturn’s rings give the planet a unique appearance
and a special beauty (Fix, 2006: 267). Saturn is twice as far from the Sun as Jupiter is and
receives only 25% as much solar energy. This makes the temperature of Saturn
atmosphere cooler than Jupiter’s. Saturn has layers of ammonia, ammonium
hydrosulfide, and water clouds. These cloud layers are widely separated in
height, with relatively clear regions in between each layer. The layers of
clouds exist at about the same temperatures as the clouds on Jupiter, but they
lie deeper in Saturn’s atmosphere, so they are beneath much more gas. It is
difficult to explain the more subtle, uniform colors of Saturn. One possibility
is that the greater depth of the cloud layers on Saturn protects them from the
ultraviolet radiation that can produce chemical reactions resulting in colored
molecules. Another possibility is that updrafts, which might bring colored
molecules up from great depths, are more gentle and uniform for Saturn than for
Jupiter. Still another possibility is that the colored molecules are produced
by lightning, which may be less common for Saturn than for Jupiter (Fix, 2006:
277). Saturn has 17 satellites, there are Titan, Rhea, Iapetus,
Diane, Tethys, Mimas, Enceladus, Hyperion, Phoebe, Janus, Epimetheus, Atlas,
Prometheus, Pandora, Telestro, Calypso, and Helena.
I loved this planet because of its ring. So pretty.

"URANUS"
William Herschel’s discovery of Uranus in March 1781 is
usually described as an accident. This is a little misleading. It is true that
Herschel didn’t set out to find a new planet. However, the discovery is best
described as serendipitous rather than accidental or lucky. William Herschel
(1738-1822) was a professional musician who began a new career as an astronomer
at the age of 30. He discovered Uranus in March 1781 while he was working on a
project to measure the brightness and positions of all the naked-eye stars and
the brighter stars that can be seen through a small telescope. Because Herschel
was extremely thorough and because Uranus was bright enough to fall within the
range of brightness he set out to study, it was inevitable that he would
observe it during the course of his observations. Herschel is acknowledged as
the discoverer of Uranus even though it must have been observed by many people
from prehistoric time onward. uranus is bright enough to be seen with the
unaided eye but had always been mistaken for a faint star. In fact, it was
recorded on at least two dozen maps of the sky made before Herschel began his
work. Herschel was the first person to notice the motion of Uranus and realize
that it wasn’t just another faint star. Herschel named the new planet “Georgium
Sidus” or “George’s Star”, after the ruling monarch of Britain, but this name
soon faded from use. The name Uranus, originally proposed by the German
astronomer Johann Bode, eventually became accepted. Bode proposed the name
because, in Roman mythology, Uranus was the father of Saturn just as Saturn was
the father of Jupiter. The discovery of Uranus made Herschel famous. King
George III granted him an annual stipend that made it possible for him to give
up his musical career and become a full-time astronomer. He built a number of
large telescopes. With them he carried out important studies of double stars,
the Milky Way, and nebulae (Fix, 2006: 292-293). Uranus has 15 satellites, there are Ariel, Umbriel,
Titania, Oberon, Miranda, Cordelia, Ophelia, Bianca, Cressida, Desdemona,
Juliet, Portia, Rolsalind, Belinda, and Puck.
It looks like full of liquid, wew. All of the surface looks like contained of water, blub blub blub. How if we take "spa" just for a while in there? Heheheee :D

"NEPTUNE"
The discovery of Neptune is often cited as a triumph
of celestial mechanics. In reality, though, it required some luck, too. Urban
Leverrier, a young French astronomer, assume that the unknown planet had an
orbit twice as large as that of Uranus, just as Uranus’s orbit was twice as
large as the orbit of Saturn. Given the data and the methods used by Leverrier,
there are many possible orbits that could account for the perturbations on the
orbit of Uranus. Leverrier found an orbit that coincidentally put the
calculated planet near enough to the actual planet that Neptune was discovered
(Fix, 2006: 293-294). Neptune has eight satellites, there are Triton, Nereid,
Proteus, Larissa, Despoina, Galatea, Thalassa, and Naiad.
It seems too cold and frozen...
