Of all the stars in our galaxy we find our Sun the most important.
For supports life on earth and keeps the planets in a certain
"line".Without the sun we could not survive.

History of the Sun

People have studied the stars since day one. Many cultures have
studied and worshiped the sun. This was the earliest form of studying the
moon. In 1611Galileo, using the telescope that he invented, discovered dark
spots on the moon. Galileo blazed the way for study of the sun. His
observations helped to lead the sun being viewed as an evolving body. Soon
its properties and variations were understood scientifically. After
Galileo the next major discovery of the sun came in 1814. A German
physicist by the name of Joseph von Fraunhofer developed the spectroscope.
This tool is used to beak down light in to wavelengths. Isac Newton had a
mild idea of this in his day, but nothing of this accuracy or detail. The
German Scientist paved the road for theoretical explanations of the star.
Some of the most recent tools that have been invented to help study the sun
are the coronagraph, the spectroheliograph, the magnetograph, and the
spectrograph. These tools have enabled us to better understand the
magnetic field of the sun and individual characteristics of the sun.

Composition of the Sun

The radiation that Earth receives from the sun is quite remarkable.
The radiation that we receive varies less than 1% over a period of twenty
four hours. However this less than one billionth of the radiation given
off by the sun. This energy comes from deep with in the sun. The
composition of the sun consists of 71percent hydrogen, 27 percent helium,
and 2 percent of other heavier elements. This makes the sun, like others,
very volatile
At the center of the sun we find the density of the sun to be more
than 150 times that of water. For this reason the center of the sun sits
at a scorching 29 million degrees Fahrenheit. At this heat hydrogen atoms
are under going nuclear fusion. Nuclear Fusion forces two hydrogen
molecules to bond together to make one helium nucleus. The energy that is
released is called gamma radiation.
Sun Spots

The magnetic field of the suns sunspots were discovered in 1908 by
an astronomer from America by the name of George E. Hale. A common sunspot
on the sun has a magnetic field strength of 2500 gauss. To put this in
relation the earth's magnetic field can be measured at less than 1 gauss.
These sunspots we tend to find in pairs throughout the sun. In these
paired sunspots we find the magnetic fields opposite directions, one into
the sun and one away from the sun. There is a changing cycle of the amount
of sunspots that can be observed every 11 years on the sun.
The phenomena of the sun spot is understood very well. One other
thing we do know about these spots are that they last, on average, no more
than a few months. This is a branch of astronomy that leaves much to be

Chesapeake Bay Pollution

The Chesapeake Bay is America's largest estuary and one of the world's most productive. The Bay is home to over 2,700 species. It draws water from over 150 rivers, streams, and creaks, receiving roughly 70,000 cubic feet of water every second. That water reflects the surrounding land use activities of the District of Columbia, parts of New York, Pe...

What Is Physics?

As I researched, I found many different definitions of Physics, some being very complex and others being simple and to the point. In defining physics, firstly, I would have to mention that the early history of physics is interrelated with that of other sciences, maths and concepts. As we know, the first areas of physics to receive close attention...

Lime Disease

Lyme disease is caused by Borrelia burgdorferi, which is a tick-borne spirochete. The dangers of this disease became more publicised in 1977, where a geographic grouping of children in Lyme, Conneticut were thought to have juvenile rheumatoid arthritis1. Soon after, it was discovered that lyme disease was an illness that mainly affects the skin,...
