Earth
The Moon
Uranus
The surface of Mercury consists of cratered grounds, smooth
plains and many deep craters similar to those on the moon. The
craters formed when meteors or small comets crashed into the
planet.
Like the first four planets from the Sun (Venus, Earth and
Mars) Mercury is made mostly of rock and metal. Mercury's
surface appears to be much the surface of the Moon.
Venus
Venus is the brightest object in the sky besides our Sun and
the Moon. It is also known as the morning star because at
sunrise it appears in the east and it is also called the evening
star as it appears at sunset when it is in the west but it can’t
be seen in the middle of the night.
A Venusian day is 243 Earth days and is longer than its year of
225 days. Oddly, Venus rotates from east to west instead of
west to east like all the other planets! If you were on Venus,
the Sun would rise in the west and set in the east.
Earth is a rocky world that is
still very much alive and
active. Volcanic activity
continually creates new land
and Earthquakes often
reshape the landscape.
Earth's surface is constantly
changing. The crust is divided up
into several "plates" (like a cracked
eggshell) that float on a sea of
rock. Where these plates collide, the
land is pushed upwards to create
enormous mountains. The tallest of
these mountains, Mt. Everest, rises
29,028 feet (8850 m) above sea
level. In some places, one plate sinks
underneath another, forming deep
valleys and trenches.
Jupiter
Saturn
In astronomy mythology, Saturn was the god of
agriculture, he was called Cronus by the
Greeks. He is the son of Uranus, and father of
Jupiter. Saturn over threw his father to
become king of the gods, but was then over
thrown himself by his son Jupiter.
Uranus
In astronomy mythology, Uranus was the lord of the skies
and husband of Earth. He was also the king of the gods
until his son Saturn overthrew him.
It would take you many years to fly a rocket to Uranus.
When you arrived you would weigh more because Uranus
is bigger than the Earth . If you weigh 70 pounds on the
Earth you would weigh 82 pounds on Uranus.
Neptune
In astronomy mythology, Neptune was originally only the
god of water, but was later extended to the ocean when
he became associated with the Greek god Poseidon.
The planet Neptune was discovered by John Couch Adams,
Urbain Jean Laverrie, and Johann Gale in 1846. With the
discovery of Uranus in 1781 scientists had a difficult mystery to
solve. The planet Uranus did not obey Newton's laws of
motion. Its observed orbit did not follow the path that it
should have.
1991, in La Paz, Baja California, in Mexico. The Moon's shadow on the Earth traced out a narrow
Eclipse
Watching a total solar eclipse through special darkened lenses or with
the Sun projected on a screen can be a marvellous experience.
During a total solar eclipse astronomers can study the outer layers of
the Sun’s atmosphere. These layers, called the chromosphere and
ending of a corona, become easy to observe when the bright disc of the Sun,
known as the photosphere, is covered. Usually they are lost in its
glare. Astronomers often pack equipment into an aeroplane and fly
along the path of totality, to spend as much time as possible
studying the Sun. For many years, this was the only time they could
study the corona. Now they have instruments and telescopes in
space to make observations at other times.
We do not usually look directly at the Sun because of the brightness of
its glare. During an eclipse, it is very tempting to do just that. You
should never look directly at the Sun with the naked eye, or with a
telescope or binoculars. It could damage or even destroy your sight.
Galaxy's
The Virgo Cluster is a group of galaxies some 50
million light years from us. It is the nearest
galaxy cluster to the Local Group of galaxies, in
which our own Milky Way galaxy is located. The
Virgo Cluster is moving away from the Local
Group at several hundred kilometres per second.
The two largest galaxies in this image of the
centre of the Virgo Cluster are the bright
elliptical galaxies.
The surface of the sun is shown here in false
colours. Sunspots appear yellow, although
they would normally appear as dark spots.
Sunspots are often larger than 30,000 km
(20,000 mi) and appear in cycles of 11 years.
Solar activity, including the development of
sunspots, is associated with the sun’s
changing magnetic fields.
