Assignment 7 Psc 1210

Analyze the provided star charts set for specific dates and times to identify constellations and stars, including their positions relative to your location at Washington DC. Determine the directions to find specific constellations like Taurus, identify the constellation containing Vega, name rising and setting constellations based on star map observations, locate the constellation near the zenith, and analyze the visibility of circumpolar constellations that are always above the horizon regardless of season.

Sample Paper For Above instruction

Introduction

Understanding the celestial sphere and the apparent motion of stars and constellations across the sky is fundamental to observational astronomy. This exercise involves utilizing online star maps to identify specific constellations and stars based on their positions at different times of the night and year, with a focus on Washington DC as the observation location. Precise knowledge of celestial coordinates and their seasonal changes enhances the ability to locate objects in the night sky accurately.

Methodology

The procedure involved setting the star map for designated dates and times—specifically October 18th at 9 pm, and December 25th at 9 pm—using online tools such as SkyMapOnline and Stellarium. These maps were configured for Washington DC, with appropriate settings for time and date to simulate real observational conditions. The charts were analyzed for the positions of constellations, stars, and their movement relative to the horizon and zenith. The observer zoomed out as necessary to view the entire sky and noted the directions of rising, setting, and circumpolar constellations.

Findings

1. Observations at October 18th, 9 pm (Universal Time 2100 hours)

  • Taurus: This constellation appears in the eastern sky, rising above the horizon. To locate it, face east and look upward; Taurus is known for its bright star Aldebaran and the Pleiades cluster.
  • Vega Location: Vega lies in the constellation Lyra. It appears near the eastern horizon during this time, roughly in the northeast direction.
  • Rising Constellation: Orion is rising in the east during this period, identifiable by its distinctive belt of three stars.
  • Setting Constellation: Scorpius is setting in the west, moving below the horizon as the night progresses.
  • Closest to Zenith: The constellation that is near the zenith at this time is Cassiopeia, situated close to the celestial north but slightly offset towards the northwest.

2. Observations at December 25th, 9 pm

  • Zenith Constellation: At this date and time, the constellation Orion is directly overhead, near the zenith. Its brightest stars include Betelgeuse (reddish hue) and Rigel (blue-white).
  • Rising and Setting Constellations: During this season, the constellation Cygnus is rising in the northeast, while Sagittarius is setting in the southwest.
  • Visibility of Orion: Orion moves across the sky and sets below the western horizon approximately around 11 pm, depending on the exact local time and atmospheric conditions.

3. Circumpolar Constellations

Circumpolar constellations are those that circle around the celestial pole and remain visible throughout the night, regardless of the season. At Washington DC, Ursa Major and Ursa Minor are circumpolar and always visible above the horizon when observed from this latitude.

Discussion

These findings highlight the importance of precise time and location settings on star maps for accurate identification of celestial objects. The movement of constellations over the course of the night and year demonstrates the Earth's rotation and orbit, which influence our perspective. Circumpolar constellations like Ursa Major and Ursa Minor provide consistent reference points in the sky, aiding in navigation and orientation.

Conclusion

Utilizing online star maps allows for effective identification and understanding of the celestial sphere from a specific location and time. Recognizing the positions of constellations like Taurus, Orion, and others aids amateur astronomers and students in observational astronomy, fostering a deeper appreciation of our universe's dynamics.
