NGC 582; (left) and the 15.2 magnitude PGC 1028168. (Right). While NGC 582 was an easy object in the 18 inch, the PGC galaxy was not seen with certainty. A galaxy is, by definition, any large collection of stars that can be recognized as a distinct physical entity. In terms of the number of stars, a small 'dwarf irregular'…
Diagram Lab-Plotting the Stars Part I: Introduction 1) One method scientists use to measure the distance of the star is called parallax. Parallax shift is when closer stars shift positions against the farthest stars. In order for astronomers to measure that distance, they measure the distance of the shift, also considering the diameter of the Erath’s orbit. Then the angle of the parallax is measured. The smaller the angle of the parallax shift is, the farther away the star is from the earth…
resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. The spiral arms, which wind all the way down into the nucleus, are made up of young, bluish, hot stars formed in the past few million years. They also host a population of stars formed in an episode of star formation that started about 600 million years ago. The greenish regions are dense areas of bright star formation. The ultraviolet light from hot young stars are…
Messier added this galaxy to his catalog of nebulas objects, known as the messier catalog. Later on June 6, 2006 the Galaxy Evaluation Explorer, from NASA, found that there were a large number of new stars on the outer rim of the galaxy, which was believed to be lacking in the material needed to make a star. The Galaxy Evaluation Explorer also found…
tilt of 23.5 degrees relative to the “ecliptic plane” the imaginary surface formed by its almost circular path around the sun the tilt towards the sun is maximised during northern hemisphere summer in late June the summer solstice. There are so much stars in the galaxy that some of them we can not discover in the universe.At night you can see some of the milky way. The sun is actually closest to the Northern hemisphere in winter not summer and the sun is always closest to the Northern…
Female pop stars have been a force to reckon with within the modern music industry and have dominated music charts around the globe. Each female pop star creates her own unique sounds, lyrics and catchy music to entice a fan base to follow them. However, are female pop stars really that different? Jennifer Lena argues in "Chapter 2: Three Musics, Four Genres: Rap, Bluegrass and Bebop Jazz" that "music histories are full of hints that there is a pattern to the evolution of communities of sound"…
morning star. But then Goofy started to run as if he wanted to show something. Zhana followed him up to the hill, realising that something spectacular was about to happen. An illuminated figure threw a twig that Goofy ran to catch it. As Zhana looked up to the sky, a flying dish was rumbling. In one lightning move, it dwindled to the vanishing…
Entry 5: For the analysis of Public Women, we focused on the era of the early to mid 1800s. Specifically we read the speech of Angelina E. G. Weld. She stood in front of a large audience of curious southerners to address the controversial subject of slavery. This was her first break at becoming a public woman. She confronted the stereotypes of a woman’s place in the industrializing American country and found a space, her public, to exhibit her strengths and opinions. Weld did this by not…
the study of heavenly bodies, as they considered celestial bodies to be divine. Travelers at that time relied on the knowledge of the stars to guide them around. Later on Muslims adopted…
Rotation is the action of moving an object around a center and this concept is fully shown in the movie “The Martian”. The rotation however depends on the concept of angular momentum, which is the rotational analog of linear momentum. This quantity is and will be the same for any rotating object and will not change unless it is ever impacted with an external force. In this case per say the Earth or Mars, rotating about its axis the physical quantity will always be conserved. Thus poses the…
