a magnifying glass for the unknown



   
    Who invented the telescope? Why is the telescope important to life as we know it? It is still unknown who invented the telescope, but the first person to apply for a patent for it was a Dutch eyeglass maker named Hans Lippershey (or Lipperhey), so he got the credit for it. One story goes that he got the idea of the telescope after watching two kids in his shop hold up two lenses that made a weather vane that was far away seem like it was closer. Others suspected, at the time, that he stole the design from another eyeglass maker named Zacharias Jansen.
Galileo had heard of the telescope and made one of his own with some improvements. He was the first person who decide to point it up at the sky to see what he could observe. It is thanks to these people that we have the technology we do today. Back then, before the telescope, we didn’t have solar panels, implantable heart monitors, water purification systems, and many more. It is simply the science of space that has improved our knowledge.

As technology evolved, scientists were able to see other stars. In the 19th century astronomers gathered information about the chemical composition and motions of celestial objects using a new instrument called a spectroscope. In the 1970’s people began to build what would later be known as the hubble telescope. On April 25th, 1990, the Telescope was launched into an orbit roughly 380 miles above the earth's surface.
Today we can use technology like this to observe other planets and moons, and other celestial objects. For me I don’t think life would be the same without the telescope. I would still think that there are only a few other planets. I would never be able to ask big questions, like what isn beyond the observable universe, how far can we travel, and most of all, is there other life somewhere out there? Without the invention of the telescope people like me would have never wondered about these questions because they thought they knew what was out there, but really they had no idea.

The Telescope


The Telescope


The first recorded and working telescope was made in 1608. This is relatively new technology, and has increased rapidly since then. The first telescope is credited to a man named Hans Lippershey, although there is some speculation about this. Hans Lippershey made a refracting telescope, one of the earlier kinds. A refracting telescope uses a lens as the objective to form the image. This was the first kind of practical telescope.

In 1609, Galileo came out with the next new kind of telescope. It was based off the one Lippershey had made, but had about 3x magnification. Galileo later went on to make a 30x one. This is sort of how science works, someone making an invention, and then someone else taking their idea and making it better. Johannes Kepler did just this, in 1611, when he made a telescope that used a convex lens, unlike Galileo’s concave one.
Into modern times, the Hubble telescope was launched in 1990. It has a 2.4 meter mirror, and can see in the near infrared, near ultraviolet, and visible spectrum. It is still in use today, capturing more and more images. The Hubble space telescope was named after Edwin Hubble.

The age old wanting is for knowledge. What’s out there? How far can we go into the universe? Curiosity has ebbed its way into how we think and perceive the world, and the telescope is helping us understand a few things. There is always more to be discovered, always more missions to send to space, and always more things to see.
