What makes constellations?

Constellations are named after a Greek or Roman God. They were made to help sailors find their way. Now they are used to help more people find their way. In this world such help is very useful.

Planets, stars and Multi-verses

We live in a vast multi-verse. A multi-verse is multiple universes. As seen in the picture they are connected to eachother the Earth and Moon are in gravitational alignment.  Each one has a vast amount amount of Galexies within it.

Every star has planets that orbit it as seen on the Highlights magazine. So if every star has planets, there is a good possibility that life exists in other areas of space. Another thing the article mentioned is astronomers have recently witnessed two stars spiral together and explode. This was 10,000 times brighter than any seen before. It was the most powerful blast witnessed so far. A red Nova which this collision was is very rare.    Our galexy produces tons of Novae. Most of which are blue, a red novae appears when two stars become one. However most novea are blue. A white dwarf is the smallest and densest explosion of two stars.

We think the Universe is 13.8 thousand million years old. We made up a Cosmic Calender to help us put the events that happened in the universe in a simple understanding. In this calender every month is about a billion years and every day is 40 million years. It began with 200 million years of darkness. On January 10 Galexies heated clumps of gas until there was the first stars. On January 13 these stars galexies merged to form larger ones. March 15 Milky Way formed.
The Sun won't shine for another six billion years. The Sun birthday is August 3. Some life began September 21. The rest of it began November 9. According to this calender the first flower bloomed on December 28. At 11:59 on the 31 all recorded history in those few seconds.

The show went into detail about much more than a star. It made this Cosmic Calender as seen above.

Pluto Planet Or Not

Pluto was discovered in 1930s. In the 1990s astronomers found a lot of smaller objects beyond Neptune. The Kuiper Belt, also known as the Edgeworth-Kuiper Belt has many moons orbiting it which makes it a planet. In 2005, the discovery of Eris, an object in the belt, was slightly larger then Pluto. Should Eris be a planet? What happens when other big objects are found? Should they be planets as well? In 2006, Pluto was demoted by a vote of hundreds of astronomers, days later other astronomers signed a petition saying they would discount the vote. The arguement is far from over. In 2010 new sightings saw Eris smaller than Pluto. Possibly in 2015, we will discover if Eris is a planet and how many more there are.

What is a Supernova?


This is a vast explosion, destroys an entire star. Seen in distant galexies, they are hard to study. When they occur in nearby galexies studies can take place more readily.

The last huge Supernovea seen in our galexy, was seen by Kepler in 1604. Sinse then the brightest Supernovea in the southern sky was was 1987A. In the northern sky, the brightest was 1993J. They fell into two different groups.

Type 1 results from the tranfer of mass inside a binary (or two star system) which consists of a white dwarf star and a giant star. In general type two supernovea are a single massive star which end in a spectacular light show.

White Dwarf Star

This is a star, about the size of Earth, however it weighs as much as the Sun. It is prevented from shrinking. Electrons that are free can be packed so close together. In more massive stars the barrier can be broken when protons combine with their electron counterparts. The first white dwarf was the companion to Serius. They are in the same orbit. They are both equal to the Sun in size. They are hard to detect because they are so dim. This is the last phase of a medium mass star.

Pulsars

These were discovered in 1967 by Jocelyn Bell and Anthony Hewish at The Radio Astronomy Observatory, (now the Nuffield Radio Astronomy Observatory at Cambridge. Radio emissions are extremly distinctive. There regularity is so great observers can predict there arrival down to a millisecond.

Solar Fact Mania

Space is full of wonder, it has a lot of unreal and fasinating aspects within it. Its wonder has been in existance since the first human was in existence. The measurements of a unit is approximately 6371 kilometers.

Sun
The weight is 2707 units.  Its a yellow dwarf star. The distance from us is 149 kilometers. It will probably never become a supernova. It is 2707 units in weight. It has nine moons or planets.

Mercury
It's the first planet orbiting the sun.
The smallest planet, which daily freezes and burns because of its distance from the sun. It is named after Hermes, who is the messenger of the Greek God. Its weight is 37 units. The distance from the Sun varies from 77 kilometers to 138 kilometers. It has a day of 1416 hours, however its year is only 88 days. This planet has zero moons.

Venus
It is named after the Roman God of love and beauty. It is Earth's sister, one of the major difference is that Earth has an atmosphere. It is the first planetary body to rise and set on the Earths horizon so it is called the morning and evening star. It has a weight of 90 units. The distance from the sun is 108 million kilometers.  From Earth it has a distance of 38 million kilometers to 223 million kilometers due to its elongated orbit. It has a 5832 hour day with a year of 225 days. It has no moons.

Earth
The Earth weights a hundred units. Its Greek name is Gia and its Latin name is  Terra. It weighs 100 units and is 149 million kilometers from the sun. Its day is a mere 24 hours and has 365 days. It has one lonely moon.

Mars
This planet is colder and smaller but other than that it is like Earth. It is named after the Roman God of love. Its weight is only 37 units. It is 228 million kilometers from the sun and 4200 to 7500 kilometers from the Earth from its oval orbit. Its day is 153 hours long with a year of 90,410 days. It has 4 moons.

Jupiter
This is the first giant planet in our Solar System. Its eye is a 300 year old storm. It is named after Zues,King of the Greek Gods, after Chronos. Your weight on Jupiter would be 236 units greater then it is on Earth. Its day is only 10 hours, while its year is 4332 days. It has 64 moons, one of the most a planet has in our Solar System.

Saturn
It is named after the God of Time in Greek mythology. Saturday is named after it. Your weight on Saturn would be 106 units. The distance from the Sun is 1427 million kilometers. The distance from Earth is 1200 to 1670 million kilometers. Its day is only 11 hours, its year is 10753 days. It has 62 moons.

Uranus

It is named after the God of the Sky. It has a methane atmosphere. No one has been to its surface. The methane has an aquamarine color. Your weight would be 88 units. The distance from the Sun is 2871 million kilometers, while its distance from Earth is 2570 to 3150 million kilometers. It has a day of 17 hours and a 30660 days in a year. It has 27 moons.

Neptune
This planet is named after the Roman God of thr seas. Arguably it is the most common planet to watch. Your weight on this planet is 112 units. Its distance from the Sun is 4498 million kilometers and 4301 kilometers to 4553 million kilometers. With a day of 16 hours, its year is 60152 days. Neptune has 13 moons.

Pluto
It is still a dwarf planet. Your weight on Pluto is 6 units. The distance from the Sun is 5900 million kilometers.  The distance from Earth is 4200 to 7500 million kilometers. A day on Pluto is 153 hours while a year 90410 days. It has four moons.

Will Solar Winds take us to the Stars

"Astronomy is a humbling and character building experience." Carl Sagan

400 years ago Johannus Kepler predicted solar winds were in existence for the simple fact of comet tails being moved through space. He actually was not that far off. There isn't any wind, but there are positively charged ions, which create a wind like effect.

These Solar sails will sure help rocket carry more, because as of now most of what they carry is fuel. The Japanese have tested this out in 2010 and in 2015 the biggest load, an estimate of 13,000 square feet, will go up. The most important thing I believe is that these are recyclable.

There are three things that are needed: a continuous force from the Sun, some large thin mirrors and a launching mechanism.
