Observing with
a small telescope

By Alistair Thomson

My interest in astronomy started about three years ago. I began by buying the magazine Astronomy Now (UK magazine). The articles and features in here really got my interest going. I used the simple star chart provided each month to learn the constellations. Using binoculars (Zeiss 10 X 50ís) I began to pick out easy double stars like Mizar in Ursa Major, open clusters like M45 and nebula like M42. From time to time I would also scan the moon to see what I could pick out.

As I began to find my way around the sky a little easier I started to try and track down more Messier objects. It took a while but I eventually found three open clusters in Auriga, M35, M36 and M37. They were quite easy to see and showed up as irregular shaped grey patches or clouds. I couldnít resolve any stars. I found more and more Messier objects with the binoculars but the majority could be seen as nothing but grey cloudy patches.

X Prize

During the early part of the 20th Century hundreds of cash awards were offered by businesses and individuals in an effort to encourage the development of aeronautics. One of the most noteworthy was a $25,000 cash award put up by Raymond Orteig, which Charles Lindbergh won for his historic flight across the Atlantic in 1927. These cash prizes played an important role in developing the airline industry we have today. In the spirit of the early aeronautics awards, the St. Louis-based X PRIZE Foundation is offering $10 million to the first private company that safely launches and lands a vehicle capable of transporting three people on two consecutive suborbital flights to 100 kilometers altitude within two weeks. Seventeen teams from 5 countries have registered to compete and are currently developing vehicles in pursuit of the X PRIZE.

The X PRIZE Foundation was established in 1994 as an educational nonprofit organization dedicated to inspiring private, entrepreneurial advancements in space travel. The X PRIZE Foundation committee includes Buzz Aldrin, Astronaut on Apollo 11 and Gemini 12, and Chairman of the National Space Society. Astronaut Dr. Byron Lichtenberg serves on the Board of Trustees, as does Lindbergh's grandson, Erik Lindbergh.

First USA Bank is offering the X PRIZE platinum VISA card. Each purchase supports the X PRIZE and earns an entry in the Sweepstakes. The Sweepstakes grand prize is a sub-orbital space flight! Additional prizes include: zero-gravity flight, flight in a MiG 25 to the edge of space, and Astronaut training adventures. A teacher from Michigan (USA) won the first MiG flight and will travel to Russia this summer to experience the thrill of flying to Mach 2.7 (1,700 miles per hour) at an altitude of 80,000 feet. There is a new chance to win every three months. You can enter by e-mail or phone, just visit the X PRIZE website.

The Wonders of the Sun
by Aymen Ibrahem


On February 21st and October 21st every year, the rising Sun illuminates the sanctuary of the Great Temple of Abu Simbel, a phenomenon popularly known as the "Wonder of the Sun". The temple was built by King Ramesses the Great [Ramesses II (1279-1213 BC)].

There are no monuments or records explaining the special choice of the illumination days. It is clear that the Sun is on the same location of the celestial sphere on both days, this has led me to speculate that probably just one day is associated with the temple dedicated to the Sun (Re-Horakhty), and Ramesses himself.

To a people that worshipped the Sun and the Moon, eclipses represented very special cosmic events. In my paper "The Wonder of the Sun", using an eclipse prediction software, I scanned the eclipses that occurred during the reigns of Pharaoh Ramesses II and his father Pharaoh Seti I. I found that a total solar eclipse was visible in Egypt in 1223 BC and the Julian Day number of the eclipse's day was: J1 = 1274785.876389, (the corresponding calendar date was not available.) Checking the coordinates of the Sun on the sky globe on the eclipse's day and applying simple algebra showed that J1 corresponds to February 21, 1223 BC.

Measuring the Night Sky

Ever wonder why a circle is 360 degrees. Ancient Babylonian Astronomers noticed it took about 360 days for the sun to make a full cycle of the sky. A degree was defined as the distance the sun moved each day in relation to the background stars.

The sky that circles the earth is 360 degrees. From horizon to the opposite horizon is 180 degrees. If you stood in a field the spot in the sky directly overhead is called the zenith. From the horizon to the zenith would be 90 degrees.
