Interesting Facts - The Universe

[- Venus Transit -]
Venus Transit Transits of Venus across the disk of the Sun are among the rarest of planetary alignments. Only six such events have occurred since the invention of the telescope (1631, 1639, 1761, 1769, 1874 and 1882). The next two transits of Venus will occur on 2004 June 08 and 2012 June 06.

The latest Venus transit occcured in 1882, 122 years ago. So no human alive on Earth has ever witnessed a Venus transit! Venus takes more than six hours to track across the Sun.
[- Astronomy -]
Astronomers believe that the universe contains one atom for every 88 gallons of space.
[- Comets -]
A Comet's tail always points away from the sun.
[- Comets -]
Until the mid sixteenth century, Comets were believed to be not astronomical phenomena, but burning vapors that had arisen from distant swamps and were propelled across the sky by fire and light.
[- Debris -]
There are approximately 10,000 pieces of equipment revolving around the earth. About 3,000 of these pieces are satellites, the rest are odd bits of Debris.
[- Gold -]
According to scientists, Gold exists on Mars, Mercury, and Venus.
[- Gravity -]
A space vehicle must move at a rate of 7 miles per second to escape the earth's Gravitational pull. This is equivalent to going from New York to Philadelphia in about twenty seconds.
[- Gravity - Weight -]
A bucket filled with earth would Weigh about five times more than the same bucket filled with the substance of the sun. However, the force of Gravity is so much greater on the sun that a man Weighing 150 pounds on our planet would Weigh 2 tons on the sun.
[- Halley's Comet -]
In 1910, when it was announced that Halley's Comet would once again pass the earth, hysteria broke out in Europe, based on the belief that the arrival of this comet always heralded catastrophe. The war of 66 A.D. that brought about the fall of Jerusalem, the devastation of Rome by the Huns in 373, the Battle of Hastings in 1066 (it is Halley's Comet that can be seen in the famous Bayeux Tapestry, announcing the death of Harold), and many other tragic events did in fact coincide with the comet's appearance. Whether or not these occurrences actually had anything to do with the comet, anxiety spread throughout Europe as soon as its impending arrival was announced, and thousands of people fled to the mountains for safety. A group of French scientists published a paper claiming that the earth would be poisoned by fumes from the comet's tail. Reports of "comet insanity" and suicide attempts filled the newspapers, and "anticomet pills," guaranteeing protection from the comet's noxious fumes, were bought up eagerly. The comet, however, came and went without much incident though, it might be noted, World War I began four years later.
[- Mass -]
99% of our solar systems mass is concentrated in the sun.
[- Moon -]
The moon weighs 81 billion tons.
[- Proportions -]
More than 1 million earths would fit inside the sun.
[- Pulsar -]
A Pulsar is a small star made up of neutrons so densely packed together that if one the size of a silver dollar landed on earth, it would weigh approximately 100 million tons.
[- Quasar -]
A galaxy of typical size, about 100 billion suns produces less energy than a single Quasar.
[- Spanse -]
If the earth were the size of a quarter, the sun would be as large as a 9 foot ball and would be located a football field distance from the earth. If the entire solar system were the size of a quarter, the sun would be visible only under a microscope, and the nearest star would be 300 feet away If our whole galaxy were the size of a quarter, our solar system would be less than the size of a molecule. Other galaxies would be from a foot to 1,000 feet away.
[- Spanse -]
Scientists believe that hydrogen comprises approximately 90 to 99 percent of all matter in the Universe.
[- Spanse -]
Our galaxy has approximately 250 billion stars and it is estimated by astronomers that there are 100 billion other galaxies in the universe.
[- Stars -]
The Star Alpha Herculis is twenty five times larger than the circumference described by the earth's revolution around the sun. This means that twenty five diameters of our solar orbit would have to be placed end to end to equal the diameter of this Star.
[- Sun -]
The Sun provides our planet with 126,000,000,000,000 horsepower of energy every day. This means that 54,000 horsepower is delivered to every man, woman and child on earth in each twenty four hour period. This amount of energy equals only about two billionths of the total energy broadcast into our solar system by the Sun each day.
