See The Solar System Through A High Zoom Telescope

Scientists as well as hobbyists think of our galaxy as fascinating and extraordinary. The only way to view all of this astonishing creation is to view it using a telescope. This is the only one that allows for enough magnification to make planets and other things in space able to be viewed by the human eye. Some objects in space are so distant that they get classified as a distance in light years, or amount of years it takes for the seeing of this image at any given time on mother earth.

Telescopes, by design, take in light through a tube and then focused so it can be magnified. Therefore, because there are 3 methods in this, there are different telescopes that produce images in different ways. The main types of telescopes are:

* Refractor – This kind is a long tube-like telescope that contains a large lens on the end called an objective lens. This kind uses a series of lenses to refract the light as it comes into the telescope where it can be viewed by the eyepiece. The objective lens on the end can be made of two or more lenses combined in just the right way for strong magnification. These telescopes are simple to keep up with and are very reliable for seeing a slough of planetary objects, stars, and galaxies. The refractor though has its limitations; one cannot view distant galaxies because the refractor is limited in ability. And, the refractor type telescopes are typically more expensive than the others.

* Newtonian Reflector – This type of telescope is completely different than the former in that it takes light into the lens, send it to an opposite side mirror and the reflection is focused and then sent back to the eyepiece for magnification. This type is much stronger than the others and can make it possible to see other galaxies. But, this kind needs a lot of tuning and adjustments. The Newtonian reflector, though, is known to be a bit less expensive than refractors or Catadioptric telescopes.

* Catadioptric – This style includes an arrangement of mirrors and lenses to manipulate beams of light onto a primary mirror and then back to the viewing lens. There is no other telescope stronger than the catadioptric. This kind can magnify pretty much any space object, galaxy, or matter. They are perfect for picking up faraway galaxies, terrestrials, and are powerful enough for terrestrial viewing and photography. This type of telescope can carry a heavy cost and look very different than Newtonian reflectors and refractors.

These instruments are a fascinating piece of technology that makes it possible to see things not of this world. For centuries, people have been fascinated with space and other galaxies and universes. Telescopes make it possible for us to look up at the sky and imagine what it is like light years into the sky.

The Fascinating History Of Microscopes

The development of today’s microscope is a culmination of several attempts to find a way to magnify things with lenses and light. The microscope was just that tool that allowed scientists and other professionals to see objects through a lens to allow for humans to be able to see it. There were many inceptions of this tool that were conceived of during the time of the ancient Egyptians in 2600 B.C. Lots of other civilizations throughout the world took a try at developing this instrument and they all had their contribution to the modern day microscope. After the ancient times however, The French, English, and Germans all came out with stunning instruments that paved the way for the modern day microscope.

In the microscope’s early days, a father and son, Hans and Zacharias Janssen, created the first microscopic instrument which was simply a tube with a lens put on the end. This precursor to microscopes magnified matter from three to nine times the present size. It is debated whether it was Hans that actually invented this microscope for the son Zacharias was rather young at this time.

Robert Hooke, an inventor of England of the sixteen hundreds is well known for various discoveries and realizations in science and math. Hooke was a chemist, mathematician, man of physics, and inventor. In 1660, Hooke improved upon the design of the microscope that was able to magnify cells and tiny matter. As a matter of fact, he was the inventor of the word cells that described these microscopic organisms that he viewed underneath his crafted microscope. He was referred to as the gentleman whom lead to the birth of physics which Newton later expanded upon.

Anton van Leeuwenhoek, of the 1600’s was a brilliant and talented individual. Although the man was absent of a large fortune or source of funding for his research, he still developed many useful experiments which lead to the development of the microscope as we know it in today’s world. Leeuwenhoek however was the protege to Hooke for that he got most of is ideas from Hooke’s publications and journals. This fact though is often debated as to which one of these men were the most contributory. Since both men were experimenting around the same time, some say Hooke got his inventions from Leeuwenhoek while other individuals believe it to be the opposite.

Bettering of the design of this amazing tool in the 1700’s was slow going, then in the middle portion of the 19th century when Charles A. Spencer developed a microscope with the power we know of today. These powerful machines are strong enough to see things at thousands of times of magnification; making things that would be impossible to see, possible to see. Spencer is said to be the manufacturing of modern-day microscopes.

There were a slough of individuals who were known for their great contributions to microscopes. But, the aforementioned individuals are known as the pioneers and biggest contributors to the microscope we see today. Without the labor and dedication of these great men, we might still be searching. Or, even worse, this valuable tool might have been a thing of fiction.
