A great telescope for viewing the solar system and stars

View Comet 67P Churyumov with a Cometron 114AZ

The 2014 Cometron 114AZ is Celestron’s 114mm (4.49 inches) Newtonian telescope, with 10mm and 20mm Kellner eyepieces, offering stunning 22.5x and 45x views of the planets, Moon, and comets speeding through the solar system.

I distinctly remember counting the dollars saved until I could purchase my first telescope. Walking down to the local hobby store to pick it up was a pleasure I had been thinking about for months.

I still have this first scope. I recently discovered it sitting in a closet downstairs, forgotten about, but still usable. I was only twelve years old when I purchased it, from dollars I had saved from my paper route. A 2-inch reflector, I had first seen it sitting in the store window. It had an all white cylinder, with black trimming, and was about 20 inches in length. Mounting her was simple, but the locking clamp was crude, and the tripod unstable at times. There was no way to align the optics system of my first telescope. She was beautiful to me, my first reflector, but she didn’t offer unforgettable views of the solar system. Still, as a young boy exploring a world he had dreamed about, purchasing this first telescope was one of the best gifts I have ever bought myself.

The telescopes sold today to young people and adults deciding to experience astronomy and owning a telescope for the first time offer a far better view of the solar system and cosmos than my first reflector. Considering the recent news that the Rosetta spacecraft will near Comet 67P Churyumov during the coming days, and NASA’s future plans to drop a lander on this comet, lots of people will be desiring to take a look. Fortunately, Celestron is introducing two new Cometron telescopes for 2014 perfect for a beginner. The Cometron FirstScope and Cometron 114AZ. Two new telescopes offering beginners great views of the solar system at a reasonable price.

Ancient Astronomers Knew the Earth was Round

By the time old Christopher Columbus announces the world is round, this was old news to ancient astronomers

To ancient sky watchers, Christopher Columbus was old news

Ancient Astronomy – Humans have been looking upward at the stars in the night sky for tens of thousands of years, wondering where it all began. Prehistoric humans revered the earth and heavens above and used the stars as a guide. Thousands of years ago ancient astronomers in China and India spent whole lifetimes staring into the vastness of time and space, cataloging the patterns of stars in the night sky. By the time Christopher Columbus announced the world was round, it was old news to ancient sky watchers in many regions of the world.

Greek Astronomy and Astronomers

Around the fifth century BC, Pythagoras announces, "The world is a globe".

The earth is a globe (Pythagoras)

In the western world it’s believed the fifth century BC Greek philosopher and astronomer Pythagoras originated the idea of a spherical earth, but the possibility of this idea being borrowed from Egyptian or eastern sources exists. Two hundred years later another Greek, Aristarchus of Samos, affirmed the belief in the earth’s spherical shape. He also announced the earth spun on its axis and, like the other planets, revolved around the sun. It wasn’t until the third century BC that Eratosthenes, custodian of the library of Alexandria, used his knowledge of astronomy to measure with considerable accuracy the earth’s circumference and diameter.

Astronomers in India

Aryabhata (476–550 CE)was the first in the line of great mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy

Ancient writings show that ancient astronomers of India had ascertained the spherical shape of the earth by the fourth century BC. Verses from the Sanskrit sacred books called the Vedas written in 3000 BC refer to a sun-centered universe. A universe ruled by the sun, moon, earth, sky and dawn, all deities to ancient astronomers in India, with attributes to match their natural ability. By the first century BC, it’s clear ancient astronomers and many common people in India knew the earth was spherical in shape.

Chinese Astronomers

Chinese astronomy has roots at least 4000 years old and China is considered by most archaeoastronomers to be the oldest known star watching society on earth. Ancient Chinese pottery dated to 6,000 years ago shows scenes of the sun, moon and stars, even ancient Chinese records of the stars are depicted on bones and shells, but the oldest known evidence points back as far as 14,000 BC. Ancient Chinese astronomers were studying and cataloging the patterns of stars in the sky tens of thousands of years ago.

By the time Christopher Columbus announced to the western world the earth was round, this was old news to star watchers and astronomers in many of the most advanced regions of the world.

Collisions in Space

Space is a dangerous place
Something might have hit THEMIS-B

You could fly around forever and never hit a thing

Astronomy News – Considering the volume of bodies circling in the solar system one might think that collisions between bodies in the solar system is commonplace, but in fact collisions between bodies circling in the solar system are relatively uncommon. This is what makes a recent report by NASA of a possible collision of one of their spacecraft with a meteorite a highlight of sorts, or at least something relatively unusual. NASA reported a possible collision between a meteorite and part of the sensitive instrumentation on board their THEMIS-B spacecraft, which is one of the two ARTEMIS spacecraft, at 0605 UT on October 14. Apparently, the flight dynamics data collected on THEMIS-B indicated that it might have been struck by a meteorite, which likely means the meteorite made a slight change in the flight path of the spacecraft. According to NASA, everything is still a go with THEMIS-B’s insertion into Lissajous orbit, and up coming simultaneous measurements of particles and the electric and magnetic fields in two different locations, using both ARTEMIS spacecraft. This will provide astronomers with the first three-dimensional look at how energetic particle acceleration happens near the Moon’s orbit, in the solar wind, and in the distant magnetosphere.
