For our project, Gina is doing the research on the constellation
Leo and Jenna is doing the research on the constellation Orion. During
our weekly get-togetheres, we share information that we have found regarding
our research project and work on our web pages together. One aspect of
our research is observing these constellations using our naked eyes, binoculars
and telescopes. We are also researching specifics on the stars and
other astronomical events, such as nebulas and galaxies, within these constellations.
In addition, we are investigating how the ancient Egyptians saw these constellations
and what significance they had in their culture.
Our team (Jenna & Gina) are meeting at least once a week
to observe these constellations in the night sky. The instruments
we have been using to observe are our naked eyes and binoculars.
We also had a great opportunity to observe our constellations at the Star
Party. Here we were able to see Regulus in Leo, the Orion Nebula,
Betelgeuse and Rigel in Orion through Orion telescopes. This opportunity
enabled us to see that Regulus is a double star, which correlated with
our research findings. Although we were not able to see the Horsehead
Nebula in Orion, we were able to view the Orion Nebula and discovered that
there are actually two nebulas in Orion’s sword. Betelgeuse and Rigel
merely looked like larger dots of light, but it was obvious to see the
color difference between the two. An interesting event occurred
at the party; the waxing moon was in Leo. In this way we were able
to see that Leo is indeed part of the zodiac, or the path of the moon through
thirteen specific constellations. This in turn made Leo less visible
than usual due to the brightness of the moon. In our weekly observations
we have noticed that Orion is setting earlier and that Orion is harder
to see because of the increased light from the later setting sun.
In contrast, Leo is prominent in the sky for most of the dark hours, especially
during our observations.
Within Leo there are numerous double and binary stars, galaxies
and nebulas. Regulus is the brightest star in Leo and is actually
a double star. It marks the very bottom of the Sickle asterism. Creating
the Lion’s tail are three spiral galaxies formed in a triangular shape.
Orion is the only constellation that has two first magnitude stars, Betelgeuse
and Rigel. Along with these two, Orion is comprised of five second
magnitude stars, making it one of the brightest, easiest constellations
to find. Betelgeuse itself is an old, red supergiant nearing the
end of its life. In contrast, Rigel is a young blue-white star.
Additionally, there are two nebulas located in Orion’s Sword where new
stars are being born.
Researching ancient Egyptian astronomy has been difficult.
We have found no journal articles dealing with our topic. Recently,
we have been successful in finding non-fiction books on Egyptian Cosmology.
We have found that the stars had a major significance in their culture
and that they did see the constellations Leo and Orion. In ancient
Egypt, the Lion was revered, respected, honored and considered noble.
The constellation Leo appeared brightly in the summer months and was associated
with the annual flood of the Nile. Because this flooding enabled
agriculture and the survival of the people, the constellation Leo was believed
to hold a majestic influence on this event. Aside from this importance,
the Lion represented fire and heat in the Egyptian culture and thus correlated
with the summer months in the dry, hot desert of Africa. We are finding
information that the beliefs of ancient Egypt, pertaining to the stars,
originated from the Babylonians and perhaps even the Sumerians. Ancient
Egyptians had a zodiac, in which the Lion was represented as the King of
the Zodiac. This is proven by the archaeological find of the Circular
Zodiac in the Temple of Isis at Denderah. From the information we
have found so far, it seems that the Egyptians view the constellation Orion
as the spirit of their main God, Osiris. Shafts in their pyramids
have been found to point to a place in the sky where Orion would have been
when the pyramids were built. Additionally, there is a belief that
three pyramids in Giza are a replica of the three stars in Orion’s belt.
We chose to study these constellations because we are both very
interested in their cultural history and modern day scientific understanding.
Gina chose to investigate Leo more specifically because she is a “Leo”
by today’s astrological charts and she wanted to know more about how this
related to the stars and science. Gina was also interested in the
origin of Leo as a cultural symbol. Jenna decided to study Orion
because it has always been an easy constellation for her to find and it
reminds her of a friend that she used to view it with. Jenna knew
the Greek story of Orion, but was interested in what other cultures saw
and thought of the same constellation. We hope to find as many specifics
on these constellations as possible, including their stars, nebulas and
galaxies. Additionally, we would like to gain a better understanding of
ancient Egyptian cosmology as it pertains to our constellations, and possibly
how these beliefs were passed on to other generations and cultures.
