List the main functions of a telescope.
Telescopes, which are the main instruments for the study of the night sky, are used for looking at things that are too far and examining them. Smaller telescopes are used to look at astronomical events, while large telescopes are used for the study of astronomy. A telescope has three basic functions. Those functions are light gathering, resolving, and magnifying. A telescope makes far-away things look closer, it increases the resolution of things for more detail, and they gather more light than your eye can, making things otherwise invisible visible.
Identify the world’s largest radio telescopes.
Radio telescopes detect and amplify radio waves from space. A radio telescope looks like a large parabolic antenna and is made of metal. It consists of a radio receiver and an antenna system. Up until 2016, the largest radio telescope was the Arecibo Radio Observatory, located in Puerto Rico. The telescope is nearly 1000 feet across and 167 feet deep. It was built into a large limestone sinkhole, which covers an area of approximately twenty acres. In 2016, the construction of the gigantic Five-hundred-meter Aperture Spherical radio Telescope (FAST) was completed in China. As the name suggests, its diameter is 500 meters or 1640 feet. Today, it is the world’s largest radio telescope.
Other honorable mentions are the Very Large Array (VLA), Green Bank Telescope (GBT), Atacama Large Millimeter/submillimeter Array (ALMA), Effelsberg, Medicina, Sardinia Radio Telescope, Lovell Radio telescope, Parkes, and Square Kilometer Array (SKA).
List the advantages of making astronomical observations from space.
Since the 1960s, space-based observations allow the National Aeronautics and Space Administration (NASA) to study the universe, like the solar system and the Milky Way galaxy, in ways not possible from Earth due to the interference from the planet’s atmosphere. Telescopes in space, such as the most famous Hubble Space Telescope, can operate around the clock, uninterrupted by the Earth’s day-night cycle or its weather conditions. Additionally, space telescopes can get clearer shots of everything and especially the electromagnet spectrum of light, such as ultraviolet radiation, X-rays, and gamma rays, impossible to view by ground-based telescopes since the atmosphere absorbs most of the light.

Reply to the following post below (minimum of 100 words):
3. Describe Newton’s three laws of motion.
Newton’s first law: Every object will continue to be in a state of rest or move at a constant speed in a straight line unless it is compelled to change by an outside force. On earth, this means you will proceed until the force of gravity slows you down and returns you to the planet. Or perhaps the force acting upon you is the friction you use to slow yourself down other than the apparent brakes of a car; I immediately think of a swing; when you wish to get off of a swing, you drag your feet across the ground to create friction to slow yourself down gradually, or you could jump at the top of the swing and get as high as gravity will allow you. You will either stop the fall back to earth by landing on your feet or less athletically landing on another body part; depending on your speed, mass, and appropriate launch from the swing, you might be able to break a swing-jumping record.
Newton’s second law: The change of motion of a body is proportional to and in the direction of the force acting on it. For Newtons Second law to move an object with mass, you need force. I believe one of the most outstanding examples of this happening is in baseball. The moment the bat hits the ball, the bat is transferring its force from its mass and the power of the swing into the ball and, in a fraction of a second, sends it flying in a completely opposite direction.
Newton’s third law: For every action, there is an equal and opposite reaction. For Newton’s third law, the old saying what goes up must come down rings true here.
7. Explain what determines the strength of gravity.
The gravitational pull of the earth affects all objects on earth equally. The strength of gravity is determined by the mass of 2 objects one object being more massive than another object creates a much stronger gravity upon the other smaller object. This gravitational force enacted upon us is what gives us our weight. According to exploratorium.edu, at my weight on earth of 180lbs on Pluto, I would weigh a total of 12 lbs, while on the sun, I would weigh a whopping 4872.9lbs. While 154 plutos could fit on earth, it would take about 1 million earths to fill in the sun (exploratorium.edu).
11. Explain the following:
a. How an object (such as a satellite) can be put into orbit around earth.
An object can be put into orbit by obtaining escape velocity, which is about 25,000 miles an hour; however, when it is approaching the point at which it is to orbit, earth rockets are used to slow it down and keep it in that orbit.
b. how an object (such as a planetary probe) can escape from orbit.
An object can escape the orbit by obtaining escape velocity, which is about 25,000 miles an hour, however this time, upon exiting the gravitational pull, there is zero gravity or friction or anything to slow it down, so it will maintain its current speed until it is speed up or slowed down by something.
c. how the gravitational interactions of many bodies can cause perturbations in their motions.
Gravitational attraction is a leading cause of perturbations. In our solar system, the sun’s gravitational attraction is the king; however, planets also have their own gravity, which can petrubate objects that get close enough to it.
d. how the planet Neptune was discovered.
John Couch Adams discovered Neptune during his mathematical analysis of the irregularities in the motion of Uranus. So basically, It was noticed that Neptune had a Perturbation effect on Uranus that caused an abnormality that told on Neptune and told john through mathematics where exactly he could find Neptune with an accuracy of 2 degrees. However, it wouldn’t be exactly discovered a few years later at the Berlin Observatory.

A “Fermi problem or question” is a question which seeks a quick, close estimate,

A “Fermi problem or question” is a question which seeks a quick, close estimate, which is either difficult or impossible to measure without complicated calculations. It is [answered] based “upon understanding of the world, upon everyday experience, and upon the ability to make rough approximations, inspired guesses, and statistical estimates from very little data” (Philip Morrison, 1963).
Here is a good explanation with examples: https://en.wikipedia.org/wiki/Fermi_problem (Links to an external site.)
Example: Estimate the number of steps you would take to complete the Appalachian Trail. (Note: In your work, the more steps you show in solving the problem, the more credit you can earn, even if your estimate is too far off).
Establish some sensible limits: 1, 10, or 100 miles is too short (the trail crosses several eastern seaboard states); 10,000 or 100,000 is too long (the circumference of Earth is about 25,000 miles).
Make a sensible estimate of the trail in miles based on your limits: About 2,000 miles.
Estimate an average step length (2 feet).
Estimate how many steps there are in a mile: About 2,500 steps per mile.
Multiply the number of miles by the number of steps per mile to determine the number of steps: 5 million steps.
Check your answer using Google: 2,200 miles for the Appalachian Trial, 5,380 feet per mile, and 2.2 feet per step. (2,200 x 5,380) / 2.2 = 5.38 million steps
For this Week 3 calculation assignment, carry out the following Fermi problems and check your answers using Google once you complete your calculations. Comment on how accurate your answers are and what you could do to get a more accurate answer for the Fermi problems. You will have to do some internet research to find factual information to back up your calculation. For example, how many kilos does an average person eat a day, when looking at how much food you would need for a trip to Mars? You need to include your reasoning and the steps you take to get to an answer like the example above.
Question 1: Estimate the mass of food and water that a team of six astronauts would need for a standard two-year mission to Mars. (Note: the two years includes the round trip.)
Question 2: Estimate how long it would take to drive from Los Angeles to New York City.
Question 3: Estimate the number of apples produced per year by a mature honey crisp apple tree.

Preface When I Heard the Learn’d Astronomer By Walt Whitman When I heard the lea

Preface
When I Heard the Learn’d Astronomer
By Walt Whitman
When I heard the learn’d astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I sitting heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander’d off by myself,
In the mystical moist night-air, and from time to time,
Look’d up in perfect silence at the stars.
Introduction
In a previous module, we learned that astronomy is an observational science, rather than an experimental science. In AST 111, you are becoming familiar with the long, painstaking process that astronomers undertake to deconstruct light from their observations, for example, using the reflected sunlight of an asteroid to determine whether it will hit Earth. This assignment affords students with the opportunity to participate in one of the first steps of the scientific process in their own place-in-space: observation of the natural world.
Assignment
In this assignment, each student will find a safe place to observe nature for 30-minutes. While students are observing, they may take photos, take notes about what they are observing, create something in response to their environment, make a data table recording how many similar or different things they saw, or simply observe.
After this experience, students shall generate an essay describing their experience, thoughts, and observations. Include responses to the following questions in your essay:
how do you think about the term “nature” and how did it influence your choice of location for your observation?
to what extent and in which ways did you consider yourself individuated from the nature you observed, if at all?
to what extent and in which ways did you consider yourself connected or part of the nature you observed?
to what extent do you think nature is the same as science? Why?
to what extent do you think observation is a part of science? Why?
The structure of the essay should have proper university-level form, with paragraphs that begin with a topic sentence and are followed by supporting sentences. However, the organization of the essay is up to the student, and may be sectioned according to clarifying subheadings. The student may include artwork (e.g. collage, poetry, visualization) or data tables related to their observations to add dimension to their essay’s interpretation. However, if these are included, they should be referred to and interpreted within the body of the essay. Any additional figures such as these shall not detract from the required word count.
The essay will be graded on a 10-point scale according to the level-of-detail provided, creative crafting, organization, appropriateness for public readership, and grammar. The essay shall be single-spaced, font-size 12, 800 – 1000 words.
Note: Please review the rubric feedback on your Relationship to Science Essay to learn about how this assignment will be graded according to the rubric (full points or otherwise).
