Andromeda “The Chained Woman” Ἀνδρομέδα Cherelle Gilger Physics 1040 section 6 TR 10 Constellation Paper
Andromeda is an autumn constellation that is V shaped the best time of year to view Andromeda is during the month of November with the suggested time being 9pm. It occupies 722 square degrees and is located close to the North Pole in the first quadrant of the Northern Hemisphere. Andromeda can be seen at latitudes between +90 degrees and -40 degrees. Using the equatorial coordinate system Andromeda’s right ascension is between 22h and 57.5m and 2h 39.3m and its declination is between 53.19 degrees and 21.68 degrees. The brightest star in the constellation is alpha Andromedae it is known as “the Head of the Woman in Chains” this star is also known as delta Pegasi “the Naval of the horse”. To the naked eye alpha Andromedae appears as a single star but it is actually two stars in close orbit, this is known as a binary system. Located almost exactly on the prime meridian of the heavens this bright star is known as one of the “Three Guides”. The remaining two stars that complete the “Three Guides” are beta Cassiopeiae and gamma Pegasi. The second brightest star is a red giant located on Andromeda’s left hip known as beta Andromedae or Mirach. It is the 56th brightest star in the Earths sky at 197 light years away [11]. Upsilon Andromedae is a white main-sequence star, similar to our own sun. It is located 44 light years away with an estimated age of 3.1 billion years. Upsilon is the tenth brightest star in the Andromeda constellation. In 1999 three planets were discovered orbiting Upsilon making this the first system of planets to be discovered outside of our own. [12] NGC 7662 is a blue snowball planetary nebula in Andromeda. It was featured as the Astronomy picture of the day on November 21, 1996. [13] The picture featured has been altered to highlight the emissions of certain ions. Gamma Andromedae is approximately 350 light years away from Earth is the third brightest star in the Andromeda constellation. To the naked eye it appears as a single star but it is really a quadruple star system with contrasting colors [1]. Objects of Interest Andromeda is home to a large spiral galaxy known as the Andromeda Galaxy. There is a wide hazy patch located half way up on the right side of the constellation this is known as the Andromeda Galaxy. The Andromeda Galaxy is the most distant object visible to the naked eye. The galaxy includes NGC206, a bright giant star cloud. It is known for 14 dwarf galaxies as its satellites. Messier 32 and Messier 110 are the two that are the easiest to find in the night sky. The first elliptical galaxy ever discovered is Messier 32. It is a satellite galaxy to the Andromeda Galaxy. M32 is small, but quite bright, and can easily be seen in a small telescope. [10] The galaxy is suspected to have been much larger at one point, but then lost its outer stars and globular clusters when it collided with the Andromeda Galaxy. Messier 110 is a dwarf elliptical galaxy. It is often classified as a dwarf spheroidal galaxy. In the halo that surrounds it there are eight globular clusters. Atypical for a dwarf elliptical galaxy, M110 is showing signs of recent star formation. It does not appear to have a supermassive black hole, or at least there is no evidence that one exists at the center of the galaxy.
