Earth-Like Planet Discovered 50 Light Years Away European astronomers have discovered a planet less than 50 light years away. This planet has come to be known as a sort of super Earth. It takes only ten Earth days to orbit its sun (much like our own) and the surface of the planet is scorc...

Voyage to the Planets The solar system holds many scientific mysteries. It is a universe full of wonder. What exactly is it? How was it created? When? Why? These are just a few of the many questions we ask ourselves all the time. In the following, the mysteries of this solar system, how...

The Solar System consists of the Sun, the nine planets and their satellites; the comets, asteroids, meteoroids, and interplanetary dust and gas. It is composed of two systems, the inner solar system and the outer solar system. The inner solar system contains the Sun, Mercury, Venus, Earth and Ma...

Nicholas Copernicus was never supposed to be a revolutionary in the field of revolutions. This Polish merchant's son, groomed to be a church canon, was not the sort of man to be running around changing the world; he was not even published until near his death, in 1543. Copernicus had been pre...

The Renaissance was a time for reform. Renaissance, French for rebirth, describes the intellectual and economic changes that occurred in Europe from the fourteenth through the sixteenth centuries. During this time, Europe emerged from the economic decline of the Middle Ages and experienced a ti...

Saturn Saturn is the sixth planet in our solar system and is the second largest planet. The only planet larger then Saturn is Jupiter. Saturn is commonly noted for its phenomenal system of rings surrounding this gaseous planet. It is also one of the outer planets. Saturn's pe...

The human conceptualization of the solar system dates back to the beginning of time. The early Egyptians worshipped the sun as a source of life and then the area called space was becoming a curiosity to humans. Throughout history, our knowledge of the solar system has increased and there is stil...

Jupiter And It's Moons Jupiter, the largest of the Jovian planets, reigns supreme throughout the solar system. Named after the Roman god Jove, the ruler of Olympus; "Jupiter is the fifth planet from the sun and is also the largest planet in the Earth's solar system. It is ...

?Jupiter is the largest planet in the solar system that named after kings of gods in Roman mythology. Also, ancient Greeks called the Jupiter- Zeus, whom is the king of the Greek pantheon. ("Jupiter, Largest") In early days of 1610, the father of the modern astronomy Galileo, who made it ...

Space Rock . Eros Eros is an asteroid but can be called a minor planet. It orbits the sun that sometimes causes it to closely pass as 14,000,000 miles next to Earth. Scientists believe that Eros comes this close to Earth every 31 years. The last time Eros came close to Earth was back in 19...

Eight Scientist Research Since the dawn of time, man has yearned to know the origin of existence, how life was started, and the source of creation. Many scientists, from ancient Greece to modern civilization, began the search for answers by first studying our solar system, mapping the s...

THE BEGINNING OF ASTRONOMY Early races believed that the earth was flat and stationary, with the sky rotating round it once a day. The early races also believed things that sound weird to us today like the Vedic priests of India believed that the earth was supported upon 12 massive pillars and duri...

Towards the end of our solar system lies the smallest of all the nine planets, Pluto. In 1905, Percival Lowell, an American astronomer, found the force of gravity of some unknown planet to be affecting the orbits of Neptune and Uranus. In 1915, he predicted the location of a new planet, and began se...

Synchronous Orbits of Communication Satellites The orbits of communication satellites vary for the type of satellite it is. The type of satellite it is depends on the work it is designed for. For example spy satellites (and most of the LEO satellites) need to be close to earth to take clearer pi...

Venus is one of the brightest objects in the sky, so it is clearly visible to the naked eye. It can be tricky to see because it is always near the Sun. So it rises and sets with the Sun each day. Venus rotates "backwards," so the Sun rises in the west and sets in the east. Ancient ci...

In the late 1400's to the mid 1500's, people believed that the earth was the center of the universe. Ptolemy stated that the Earth was stationary and that the sun, moon, planets, and stars revolved around imaginary points, which in turn revolved around the Earth. Copernicus knew that natu...

Can the Earth be the only place in the Universe that harbors life? Most astronomers don't believe this is true. Certain statistics in the Universe provide evidence that living beings may be common place through out the universe, on planets of other stars besides the sun. In this paper I plan to dis...

Throughout the history of astronomical theory, there have been two main theories on the setup and placement of the heavenly bodies within our observed universe. The two theories are the geocentric model, our earliest theory, wherein the earth is at the center of everything, and everything rotates ar...
