Astronomy Description

There are billions upon billions of stars in our galaxy but only about 2000 of those are visible to us at night. Although there is one star that we are able to see during the day, but only because it is the closest one to earth, this star is the sun. Because the brightness of the sun is so vast we cannot see other stars, but when the sun sets we can see an abundance of celestial objects. The sun appears to be what some would call “the largest star” but it is only an average sized star, there are a countless more that are hundreds times the size of our sun. When we look up into the night sky and focus our eyes on what appears to be a star we often notice it twinkling, this is caused by turbulence in earth’s atmosphere. The atmosphere is like a lens and makes a boiling effect causing stars to look like they’re twinkling. Astronomers have discovered clusters of stars forming patterns, we call them constellations and there are roughly eighty-eight in our night sky. Stars can come in all kinds of different shapes sizes and distances, which causes some stars to appear closer than others. Bigger stars tend to shine more brightly than smaller stars. Even though a star seems bigger and brighter than the others doesn’t actually mean it is, it could just be a star closer to earth than most. The closest star to us is Alpha Centauri and is approximately four light years from earth meaning it takes four years for the light from Alpha Centauri to reach

One of the most familiar constellations in the night sky aside from the Big and Little Dipper is Orion, the Hunter. Made identifiable by the three bright stars that make up "Orion's Belt", Orion is easily recognized throughout the world due to the convenient position upon the celestial equator, allowing the constellation to be seen from both the Northern and Southern Hemispheres. I chose this constellation as my favorite because it was, in fact, one of the first myths that I had ever learned, and also because it was the easiest constellation that I was able to find from my Constellation Atlas as a child. The constellation of Orion is comprised of mostly of blue stars: young, hot burning, giant stars that range from 243 light years to 1,359

The autumn constellations Andromeda and Perseus, along with Cetus, Pegasus, Cassiopeia and Cepheus, are richly intertwined in mythology, but are vastly diverse in the objects they present to astronomers. While Perseus lies along the Milky Way, and offers many dazzling open star clusters and diffuse nebulae, Andromeda lies away from our galaxy's plane, and introduces us to the inhabitants of intergalactic space. Some of the finest celestial objects reside in these constellations, and it is well worth braving cool autumn nights to observe them.

In this assignment the author aims to describe their favourite constellation and to tell the myth belonging to the star formation before telling a new myth behind the constellation.

My Cherished Constellation is Ursa Minor, also known as the little dipper. I have always been drawn to Ursa Minor because I have a series of moles on my leg that, as a child, I would play “connect the dots” on and discovered it looked a lot like the little dipper. I also had a special connection to the Ursa Minor constellation because it is often depicted as the little bear and bears are one of my favorite animals. Ursa Minor is the 56th constellation in size and contains one of the brightest stars and most significant stars in the sky, the North Star (or Polaris). This constellation belongs to the Ursa Major family of constellations, which includes such constellations as Draco, Leo, Lync, Corona Borealis and Ursa Major. Ursa Minor is a really interesting constellation with a historical and astrological connections.

My favourite constellation is Orion, or the hunter, as it's the first one I learned how to identify when I was a kid. Orion is easiest to see from November through to February, to the south-west if you are in the Northern Hemisphere, or the north-west if you are in the southern one. It's most marking feature is the belt, three bright stars in a short line. Most of the stars that make up the constellation or blue giants or supergiants.

One of the most recognized groups of stars is the Big Dipper. It has also been called the plow and a wagon or cart. It is part of the constellation called Ursa Major or the Great Bear. According to the Greeks, the

The term Leonid refers to the tale of following the meteor trails backward to the point where it meets with the Sickle asterism which is a group of bright stars that can resemble a question mark. To spot Leo you need to first locate the Big Dipper and poke a hole in the bottom. As the water falls from the bottom of the bowl you can sometimes hear Leo roar as the water falls on him.

As proposed in an article posted on amazing space.org, “The telescope, a basic reflector with a 94.5 in (2.4 meters) mirror.” While also having being a second mirror that the light bounces to to. Within that mirror, many instruments were compacted together that allowed for clear and visible views in infrared and ultraviolet light. It was different compared to any other ground based telescope whereas it allowed astronomers to observe and witness details that had never been seen before due to Earth being in the way for those other telescopes. The telescope revolves around the earth completely every ninety-seven minutes at the speed of five miles per second, allowing for many observations in space. The observations occur when light hits the main mirror and then bounces towards the second mirror in which the second one focuses the light. The telescope began to be created in 1977 and was originally supposed to launch during the year of 1985. Unfortunately an accident had occurred when a space shuttle challenger exploded and flights into space took a halt. It was finally launched on April 4th of 1990 once the halt had stopped. The improved observations had begun and the history of astronomy had changed. Unfortunately there were some minor setbacks that had to be dealt with. One setback was that the primary mirror was ground incorrectly in which the curve of it was too flat. It was off just

On Monday, June 26, I had the opportunity to observe some planets and stars with the help of professor Lowry and his amazing telescope. What I saw and learned that night about Saturn, Jupiter and the constellations was remarkable and complemented what I have being learning in my astronomy course.

The famed Alexandrian astronomer, Ptolemy, catalogued Cassiopeia among his original 48 constellations recorded in The Almagest, and it still shines brightly to this day. Visible year-round, Cassiopeia is easily identified by its “W” shape. This distinction, also known as an asterism, made Cassiopeia one of the first constellations I could identify in the night sky. Each time I spot those five stars I am hit with a wave of nostalgia and this has caused Cassiopeia to be among my favorite constellations. While predominantly appearing in the Northern sky, Cassiopeia may also be viewed from parts of the Southern hemisphere. The stars span an area of 598 square degrees, making Cassiopeia the 25th largest of the 88 recognized constellations. Included in the formation are open clusters Messier 52 and Messier 103; the supernova remnant Cassiopeia A; a star-forming cloud known as the Pacman Nebula; and The White Rose Cluster. German-British astronomer Caroline Hershel discovered the cluster in 1783. Approximately 300 stars form this cluster, which appears as a delicate rose gently unfolding in the sky. Cassiopeia belongs to the Perseus family that also includes the constellations Andromeda, Auriga, Cepheus, Cetus, Lacuta, Pegasus, Perseus, and Triangulum.

Our planispheres are diagrams that depict the date and time a constellation or star will be visible by it passing through the meridian while facing North to Polaris. The night sky planisphere also depicts what stars can be seen during any time of the year in specific direction in the sky.

The Aquila constellation is usually described as the eagle. The stars in this constellation form an arrow in the sky. It looks similar to a bird with two large triangles spreading out on both sides and a small tail from the back. Aquila is home to Altair, which is the brightest star in its constellation but also the twelfth brightest star in the night sky. There is a picture of Aquila in the night sky in the attachment to this paper.

Earth’s galaxy, the Milky Way consists of more than 100 billion stars, many of which can be interpreted by human visual perception, while other can only be observed with the aid of a magnifying or light-collecting optical device such as a telescope. The stars are organized into various groupings according to their visible arrangement as observed in earth’s atmosphere. Human beings from cultures of eras bygone such as the Greeks, Romans, and Babylonians, and bestowed most, if not all of the titles upon the constellations as we know them today. Earth’s atmosphere comprises eighty-eight constellations, of which I have chosen the following five to discuss for my laboratory report: Andromeda, Big Dipper, Cassiopeia, Cepheus, and Draco
