Stargazing On A Budget - Make Your Very Own Astronomy Telescope!
From the desk of: Alan Dodd
I set this website up because I absolutely love astronomy. I study everything from the smallest star to planets and eclipses. However, until recently, star gazing was out of my league. I couldn't afford a telescope. That's why I want to share this website with as many people as possible.
Since you've found this website I'm assuming you love star gazing as much as I do. The truth is, I'm always on the internet looking for astronomy information and telescope innovations. While doing some research, I stumbled upon a fantastic manuscript by Mr Allyn J Thompson.
Mr Thompson is one of the most accomplished and well-known telescope makers of all time.. I noticed that most of his work was available online with the exception of one of the most important pieces of work, 'Making Your Own Telescope'. Even though it was first published in 1947, this book has the best telescope making information I have ever seen.
In the 15 chapters, here's just a snippet of what is covered:
The story of the telescope - discover what was first used to view the stars, the moon and 5 other planets.
Full instructions on how to assemble each section step by step.
Insider information on how to 'grind the lens' and spherical surfaces on the glass. This is a very specialized technique.
Where to find all the materials and tools you'll need to build your telescope.
The pitch lap°™this can be a bit dangerous, so you'll be shown the correct and safe way to do it.
How to test, correct and polish°™at this stage you'll have to be very precise so as to get the mirrors just right.
How the 'Paraboloid' works and how to get the angles right. Discover how to get the curve to its correct 'sphere.'
If this is the kind of information that you have been looking for, here's the good news...
I have contacted the original copyright owners and gained permission to republish Mr Allyn J Thompson's complete work on this website. Although I had to pay to have the manuscript reformatted and published online, astronomy is my passion. Therefore, I want to share this book with as many people as possible for free.
The information is second to none and you'll soon be gazing at the stars through your very own telescope.
Jumping Jupiter! It's "Einstein's Planet"!
The search for planets in orbit around stars other than our own Sun has proven to be a long and difficult quest, and their ultimate discovery almost a generation ago is certainly one of humanity's greatest achievements. The first extrasolar planet orbiting a star like our own Sun was detected back in 1995 and, now, almost twenty years later, astronomers have succeeded in spotting many, many more planets dwelling beyond our own Solar System than the eight major planets circling within it. As technologies improved over the years, extrasolar planets were discovered by planet-hunters using a variety of new methods. In May 2013, astronomers announced that by using predictions of Albert Einstein's two Theories of Relativity, they had discovered an enormous alien planet circling a distant star--the new-found world was appropriately nicknamed "Einstein's Planet"!
How Did the Universe Originate?
I have been contemplating about how the universe came into being. I have put across my view and hypothesis as to how the universe must have been formed.
Two Sun-Like Stars Reveal Polluted Remains
Stars of all sizes are enormous balls of roiling, searing-hot, mostly hydrogen gas. When relatively small stars like our Sun have finished burning their necessary supply of hydrogen fuel, by way of the process of nuclear fusion, they toss their outer varicolored gaseous layers into the surrounding Space, leaving behind a very dense, collapsed, remnant core called a "White Dwarf." Typically, "White Dwarf" atmospheres are very "clean", because the heavy elements manufactured in the progenitor star's heart have clumped together in this relic, very dense core. However, using the venerable Hubble Space Telescope, astronomers made the announcement in May 2013, that they have discovered two "White Dwarfs", a mere 150 light-years from our planet, that have atmospheres that are "polluted" with the rocky debris that can give birth to bizarre, new planets.
Crashing Chunks From Space Bring Water Here, There - And Maybe Elsewhere!
Comets and asteroids are relic "planetesimals"--small chunks of rock, or ice, or both, that collided and merged together in the ancient Solar System to form full-grown planets. In May 2013, astronomers announced two exciting discoveries--the first is that water secreted deep inside of our planet and its bewitching large Moon, may have had the same origins in showering chunks of tumbling ancient carbonaceous chondrite meteorites, which are now observed dwelling in the Main Asteroid Belt between the planets Mars and Jupiter. The second announcement, also amazing, is the news that the stratosphere of the gas-giant planet, Jupiter--the largest planet in our Solar System--is still filled with water delivered to it by a cataclysmic comet crash that stunned the world back in 1994. But that's not all--in October 2012 astronomers announced that an alien comet cloud had been spotted around the distant Beta Pictoris stellar system, about 63 light-years from Earth--and these alien comets could very well be potential sources of water for remote worlds circling stars beyond our own Solar System!
What's The Matter With Dark Matter?
Our bewitching sky at night is blazing with fiery luminous objects, such as stars and galaxies. However, most of the matter in our Universe is "dark"--or more precisely invisible--and scientists are "in the dark" about its alluring and mysterious nature--hence its name "dark matter"! This bizarre substance is believed to be composed of exotic non-atomic particles that do not interact with light--which is why it is invisible. Although scientists are in the process of rapidly closing in on the elusive identity of this weird and abundant stuff, its nature is still an intriguing puzzle. Adding to the puzzle, astronomers recently found that the merging galaxy cluster, Abell 520, possesses a core of "dark matter" and searing-hot gas that should be pulling in, with its mighty gravitational grip, many more galaxies than it apparently is--and this discovery is challenging existing theories suggesting that the "dark matter" should be anchoring these galaxies like a gigantic wad of glue, preventing them from wandering away into Space!
