Astronomy Questions FAQ on Galaxy - Universe & Solar System

Questions: For this question, click on Student Exercises under the SkyGuide tab. Select G:Galaxies and the Universe, then G1: Our Home Galaxy, the Milky Way,then 4:The galactic plane and the ecliptic. The following is Question6 under that section: 1. Which of these statements most accurately describes the situation of the Solar System within the galaxy? The planes of the galaxy and solar system are coincidental and parallel. The plane of the solar system is perpendicular to that of the Milky Way. The solar system does not have a plane. The plane of the solar system is inclined with respect to the galactic plane. 2. During which month does the sun cross the plane of the Milky Way? September October November December 3. Follow the instructions for turning on different objects in the NGC-IC database. Turn on the open clusters by checking the Open Cluster box. From the location of open clusters in our galaxy, which of the following statements correctly describes their distribution? Open clusters are evenly distributed throughout the disk and halo of our galaxy. Open clusters are found mainly in the halo of our galaxy. Open clusters are found mainly in the disk of our galaxy. Open clusters are found mostly around the galactic meridian. 4. For this question, click on Student Exercises under the SkyGuide tab. Select G:Galaxies and the Universe, then G1: Our Home Galaxy, the Milky Way,then 7:Galactic object distribution. Follow the instructions for turning on different objects in the NGC-IC database. Turn on the globular clusters by checking the Globular Cluster box. From the location of globular clusters in our galaxy, which of the following statements correctly describes their distribution? Globular clusters are evenly distributed throughout the disk and halo of our galaxy. Globular clusters are found mainly in the halo of our galaxy. Globular clusters are found mainly in the disk of our galaxy. Globular clusters are found mostly around the galactic meridian. 5. Our closest large, neighboring galaxy is M31, commonly called the Andromeda Galaxy. It is the only galaxy visible to the naked eye from the northern hemisphere, although it is over 2 million light years distant. Set the time and date to 1am on August 13, 2015, and find M31. Where in the sky would you look to see M31 at this time? If the weather permits, try spotting this galaxy (you do not need to wait until 1am). If you are not near any major light source (like Spokane), you should be able to see it with your naked eye. It is easy to spot with binoculars so try that if you have a pair. You should also be able to spot some Perseid meteors if you are observing around midnight or later. Low in the south High in the east High in the north Low in the west Answers: 1. The planes of the galaxy and the solar system are coincidental and parallel- This is the statement is most accurately describes the situation of the solar system within the galaxy ('Deaths Of Fellows'). The answer is the first one (a). 2. In the month of December, sun crosses the plane of the Milky Way. The equator galactic is an imaginary circle grate that to the divides the imaginary equal celestial sphere into the two equal levels of halves ('Astronomy Writing Prize'). The sphere celestial is- of course- a fiction. This is the fiction same that confounded so the stargazers early, that has been seen from our home galaxy. In the modern terms the geocentric fiction view to the enables the universe astronomers to use the coordinate workable system. The answer is the last one (d). 3. This is the open cluster turn on by the checking of the open cluster box. This is the form of location of open cluster into our galaxy, the open clusters are distributing evenly throughout the disk and halo to our galaxy. The answer is the first one (a). 4. From the location of globular cluster in our galaxy, the correctly described description is the at Globular cluster are found mainly in the halo of our galaxy. It contains more stars and are much older than the less dense galactic, or open cluster,which are found in the disk.Globular clusters are fairly common. The answer is the second one (b). 5. If the weather permits, try spotting the galaxy M31 and not near any major light source then we will find it high in the north on August 13, 2015 near about 1am.This conclusion can be drawn by the chart provided by the star hopping guide for finding the position of galaxy M31. The answer is the third one (c). Reference list- 'Astronomy Writing Prize'.Astronomy Geophysics53.3 (2012): 3.04-3.04. Web. 'Deaths Of Fellows'.Astronomy Geophysics53.3 (2012): 3.34-a-3.34. Web.
