Forensic astronomy uses the knowledge of the sky to study astronomical phenomena
in literature and art. In this lab you will use the planetarium program, Stellarium to
study three famous Van Gogh paintings which show objects in the sky. Van Gogh is
known to have often painted from nature so it is likely that many of the objects
depicted in the sky were real. Your goal is to identify the astronomical objects in each
of the paintings and compare them with the actual sky at the time.
Using Stellarium Web
Stellarium is a powerful program that simulates the entire night sky, allowing you to
observe the appearance of the stars, planets, Sun, and Moon from any location on
Earth and from any time in history. Best of all, the program is available for free as an
interactive web tool. You can use Stellarium to identify constellations in tonight’s sky,
or you can travel through space and time to see what the sky looks like from any
location on the Earth in the past or future.
● Open the web version of Stellarium in the Chrome browser. If the software
does not open, try another browser (such as Firefox).
● Watch this Overview of Stellarium Web video to learn about the essential
features of the program.
● Watch the instructor video, Understanding Time in Stellarium Web.
Two Notes about Changing Your Location
● The landscape you see (grass, trees, etc.) will look the same regardless of
your location on the earth. When you move to a new location, the ground
won’t change, but your view of the sky will.
● If you change your location to a large city like “Chicago” then Stellarium will
recognize the city’s name and display it on the map. However, if you change
your location to a small town, then it may use the name “undefined” simply
to say that it does not know the name of this location. For this reason,
throughout our lab, I will provide you with the latitude and longitude of our
Now that you are familiar with Stellarium, we will examine three Van Gogh paintings
and attempt to use forensic astronomy to identify the celestial objects he painted.

Compelling correspondence is essential to the achievement all things considered but since of the changing idea of the present working environments, successful correspondence turns out to be more troublesome, and because of the numerous impediments that will permit beneficiaries to acknowledge the plan of the sender It is restricted. Misguided judgments.In spite of the fact that correspondence inside the association is rarely completely open, numerous straightforward arrangements can be executed to advance the effect of these hindrances.
Concerning specific contextual analysis, two significant correspondence standards, correspondence channel determination and commotion are self-evident. This course presents the standards of correspondence, the act of general correspondence, and different speculations to all the more likely comprehend the correspondence exchanges experienced in regular daily existence. The standards and practices that you learn in this course give the premise to additionally learning and correspondence.
This course starts with an outline of the correspondence cycle, the method of reasoning and hypothesis. In resulting modules of the course, we will look at explicit use of relational connections in close to home and expert life. These incorporate relational correspondence, bunch correspondence and dynamic, authoritative correspondence in the work environment or relational correspondence. Rule of Business Communication In request to make correspondence viable, it is important to follow a few rules and standards. Seven of them are fundamental and applicable, and these are clear, finished, brief, obliging, right, thought to be, concrete. These standards are frequently called 7C for business correspondence. The subtleties of these correspondence standards are examined underneath: Politeness Principle: When conveying, we should build up a cordial relationship with every individual who sends data to us.
To be inviting and polite is indistinguishable, and politeness requires an insightful and amicable activity against others. Axioms are notable that gracious “pay of graciousness is the main thing to win everything”. Correspondence staff ought to consistently remember this. The accompanying standards may assist with improving courtesy:Preliminary considering correspondence with family All glad families have the mystery of progress. This achievement originates from a strong establishment of closeness and closeness. Indeed, through private correspondence these cozy family connections become all the more intently. Correspondence is the foundation of different affiliations, building solid partners of obedient devotion, improving family way of life, and assisting with accomplishing satisfaction (Gosche, p. 1). In any case, so as to keep up an amicable relationship, a few families experienced tumultuous encounters. Correspondence in the family is an intricate and alluring marvel. Correspondence between families isn’t restricted to single messages between families or verbal correspondence.
It is a unique cycle that oversees force, closeness and limits, cohesiveness and flexibility of route frameworks, and makes pictures, topics, stories, ceremonies, rules, jobs, making implications, making a feeling of family life An intelligent cycle that makes a model. This model has passed ages. Notwithstanding the view as a family and family automatic framework, one of the greatest exploration establishments in between family correspondence centers around a family correspondence model. Family correspondence model (FCP) hypothesis clarifies why families impart in their own specific manner dependent on one another ‘s psychological direction. Early FCP research established in media research is keen on how families handle broad communications data. Family correspondence was perceived as an exceptional scholastic exploration field by the National Communications Association in 1989. Family correspondence researchers were at first impacted by family research, social brain science, and relational hypothesis, before long built up the hypothesis and began research in a family framework zeroed in on a significant job. Until 2001, the primary issue of the Family Communication Research Journal, Family Communication Magazine, was given. Family correspondence is more than the field of correspondence analysts in the family. Examination on family correspondence is normally done by individuals in brain science, humanism, and family research, to give some examples models. However, as the popular family correspondence researcher Leslie Baxter stated, it is the focal point of this intelligent semantic creation measure making the grant of family correspondence special. In the field of in-home correspondence, correspondence is normally not founded on autonomous messages from one sender to one beneficiary, yet dependent on the dynamic interdependency of data shared among families It is conceptualized. The focal point of this methodology is on the shared trait of semantic development inside family frameworks. As such, producing doesn’t happen in vacuum, however it happens in a wide scope of ages and social exchange.
