A powerpoint presentation I made for our physics class. It was actually a group thing but I had to edit and start all over again but this looks not that good for me because this is a result of "cramming"! If you were part of my physics class, I swear, God bless!

1. THE TWIN
ICE
GIANTS

7. Blue-Green
Giant
Uranus is the seventh planet
from the sun in our solar
system. This giant ball of gas
and liquid is about four times as
large as Earth, and it's covered
by methane clouds. It is
believed that Uranus is covered
in ammonia and water oceans
surrounding a rocky core
believed to be the size of Earth.
In 1986, Voyager 2 passed by
the planet, illuminating the
blue-green gas giant as never
before.

8. Uranus in
Color
Uranus is in some ways most like its
neighbor Neptune, but in others it is
fantastically different. While Neptune
was the first planet to be discovered by
mathematical prediction, Uranus was the
first planet to be discovered by
telescope. It was first revealed in March
1781 by English astronomer Sir William
Herschel. Here the top picture shows
Uranus as the human eye sees it. The
bottom picture shows Uranus through
ultraviolet, violet and orange filters to
illustrate the contrast of gases.

9. High-level haze on
Uranus
This computer-enhanced photo taken
by Voyager 2 shows the high levels of
haze in Uranus' upper atmosphere.
While the planet closely resembles
Neptune in composition,
Uranus emits less colorful
wavelengths, making it a somewhat
bland planet in comparison. NASA
believes this is because the planet's
internal heat is lower than the other
gas giants. Because Neptune is at
such an extreme axial tilt, the planet
experiences different and sometimes
violent seasons.

10. Hubble finds many bright clouds on Uranus
This image was taken in 2007 by
the Hubble Space Telescope. It
shows the cloud bands, rings and
moons of the planet. These are
theplanet's four major rings and 10
of its many known satellites.
The five main satellites of Uranus
are called
Miranda, Ariel, Umbriel, Titania
and Oberon. Uranus also has the
most unique positioning among all
the planets, as it tilts almost
completely on its side. Where most
planets have its
equator, Uranus has its north and

11. Miranda as seen by Voyager 2
The moon Miranda is named for the
daughter of Prospero in "The Tempest."
It is seen here in a photo taken from
Voyager 2 in 1986. It is the smallest of
Uranus' largest satellites, but it is
considered perhaps one of the most
intriguing moons in the solar system.
Made of ice and rock, Miranda's surface
is made up of ancient and newer
surfaces, a rarity in planetary geology.
Some experts believe this combination
of surfaces was caused by partly melted
ice upwells forced new surfaces into
existence while other experts think that
Miranda may have literally shattered
and reformed itself over the centuries.

12. Crescent Uranus
This photo, taken by Voyager 2, shows
a color composite of three
photographs taken through
blue, green and orange
filters. Voyager 2, launched in
1977, photographed Jupiter in
1979, Saturn in 1981, Uranus in 1986
and Neptune in 1989. What it did not
clarify was the pronunciation of
Uranus, which can cause some
giggles. Some astronomers stress the
first syllable of the word: in other
words, yoor-uh-nuhs. However, it is
acceptable to pronounce the name of
the planet with an emphasis on the
second syllable as well.

13. A rare eclipse on Uranus
In 2006, the Hubble Space
Telescope caught a rare view of an
eclipse on Uranus. Uranus has an
extremely strong magnetosphere.
Its atmosphere is comprised
mostly of hydrogen and smaller
amounts of helium and methane.
Further, it averages
around 2,870,972,200 kilometers
(1,783,939,400 miles) from the
Sun. And while its atmosphere is
extremely cold, experts estimate
that the oceans can reach a
temperature as high as 4,200
degrees F (2,300 degrees C).

14. Voyager 2's final
image of Uranus
This photo, taken in 1986, was the
final image released by NASA of
Uranus before the spacecraft began
its journey to Neptune. Uranus also
has the distinction of being the only
planet named after a god from Greek
mythology, as opposed to Roman. In
the 18th century, German
astronomer Johann Bode suggested
that the planet be named for the
father of Saturn, as Saturn is named
for the father of Jupiter. In 1850, the
name Uranus became the universal
tag for the planet.

21. 2011:
•Neptune completes its first 165-year orbit of the
sun since its discovery in 1846.
2003:
•Using improved observing techniques,
astronomers discover five new moons orbiting
Neptune.
2005:
•Scientists using the Keck Observatory image the
outer rings and find that some of the ring arcs have
deteriorated.

23. The blue
planet
The beautiful blue orb of
Neptune, named for the Roman god of
the sea, is the eighth and farthest
planet in our solar system from the sun.
This honor used to reside with Pluto
until it was demoted from planet
status by the International
Astronomical Union. Neptune's equator
is four times as long as Earth's. It is 17
times as heavy, though not as dense.
We have one moon, while Neptune has
13. And now, thanks to the Voyager 2
spacecraft and the Hubble Space
Telescope, we can see Neptune as

24. Hubble captures dynamic
atmosphere
Neptune is one of two planets not
visible to Earth by the naked eye. This
is perhaps the main reason why it was
the first planet to be discovered by
mathematical prediction. It was
separately discovered in the mid-19th
century by English astronomer John C.
Adams and French mathematician
Urbain Le Verrier. The planet is
covered by thick clouds that move
rapidly. NASA reports that Neptune's
winds move at speeds up to 700 mph.
This color-enhanced photo taken by
the Hubble telescope in 2005 shows
Neptune as never seen before.

25. Hurricanes
Here two great hurricanes can be
seen spinning on Neptune's
surface. This photo was taken in
August 1989 by Voyager 2, the only
spacecraft to travel to Neptune. The
Great Dark Spot is seen to the
north, while Great Spot 2, with its
white center, is more to the south.
The white clouds in between were
nicknamed "The Scooter" by NASA.
The storms were thought to be
swirling masses of gases similar to
hurricanes on Earth. But when
Hubble turned its telescope on
Neptune in 1994, the storms had
disappeared.

26. On Triton's horizon
Voyager 2 generated this computer
image of Neptune as seen from its
moon, Triton. Triton is Neptune's
largest satellite and is the only
moon in the solar system to orbit
opposite of its planet. Experts
believe that Triton may have been a
large comet that orbited the sun but
got caught in Neptune's
gravitational pull. Triton boasts the
coldest known temperatures in the
solar system, at minus 390 degrees F
(that's minus 235 degrees C). NASA
has discovered evidence of
ammonia and water volcanoes on
Triton.

27. Crescents of Triton
and Neptune
When Voyager 2 took this
image, it "was plunging
southward at an angle of 48
degrees to the plane of the
ecliptic," according to NASA.
Besides its 11 satellites, Neptune
also boasts a planetary ring
system. The three main rings are
named for Neptune's first
researchers, the Adams ring, the
La Verrier ring and the Galle
ring. But recent evidence shows
that the rings are unstable and
may be deteriorating in spots.

28. Great Dark Spot
Voyager 2 took this photo
of Neptune's gigantic anti-
cyclonic storm in 1989.
Considered to be much like
Jupiter's Red Spot, the
storm was thought to span
8,000 by 4,100 miles. It was
believed to have a vortex
structure. When Hubble
turned its lens on Neptune
in 1994, the Great Dark
Spot was found to have
vanished. A new storm just
like it was found roaming
the northern hemisphere of
the planet.

29. Mosaic of Triton
This global color mosaic
of Triton was taken by
Voyager 2 in 1989. Like
Earth, Triton is thought
to have a nitrogen-rich
atmosphere, and it is
the only satellite in the
solar system that has a
nitrogen ice surface.
The blue-green band
across Triton is thought
to be nitrogen
frost, while the pink is
thought to
be methane ice.

30. Clouds
Voyager 2 took this image of
Neptune in 1989, two hours
before it made its closest
approach to the planet.
Neptune's surface is not like
Earth's. While these thick
clouds cover the surface, the
interior of the planet is made
up of heavy, compressed
gases. Its core is composed of
rock and ice. What does the
future hold for Neptune and
its moons? In 2005, a team of
researchers backed by NASA
came up with a plan to land a
team of explorers on Triton.
