Planning experiments is a very valuable skill for scientists, and the International Space Station has provided an incredibly unique Essay

Planning experiments is a very valuable skill for scientists, and the International Space Station has provided an incredibly unique environment for experimentation. In many of the other labs in this course, you’re tasked with carrying out a specific experiment or set of instructions. In this assignment, you get to plan an experiment from scratch! If you need to brush up on the basics of designing an experiment, you can Watch this video:

The “zero gravity” environment of the space station can make for a lot of interesting experiments, but that’s just a starting point and you can go in another direction if you’d like. As long as your experiment can only be done in space, it will count for this assignment! Check out this article about different studies conducted on the ISS for some potential ideas to get you started, however, you should not be copying these experiments.

Imagine you’re a NASA scientist, proposing an experiment that will be conducted on the ISS to a potential investor/supporter. Your assignment is to write a Research Proposal that contains the following information. Be sure to cite your sources using in-text citations and a reference list in APA format.

Background and Justification: What background information can you give that is relevant to the experiment? Why is this experiment important to conduct? Has other similar research been done? Remember to cite your sources for research.

Variables: What is your independent variable (the quantity you’re changing)? What is your dependent variable (the quantity you’re measuring)?

Constants: What factors have to be kept constant during your experiment? How will you make sure they are kept constant?

Assumptions: Will you be making any assumptions during your experiment? What are they? How would the outcome of your experiment be affected if you assumed incorrectly?

Hypothesis: With all of this information in mind, make an educated guess as to the results. This should be an “If —, then —-” statement.

Materials: What materials will you need? Is there anything special you’d have to bring up from Earth?

Procedure: Create a detailed, step-by-step procedure for the astronauts who will conduct the experiment. Make sure they know how to set up the experiment, what measurements they’re taking and with what frequency, as well as how and where to record information.

Data processing: Once you have your data, what will you do with it? Will you make a graph, and if so, what will it tell you? Will you run a secondary experiment based off the results of the first? How can your data be used back on Earth or on the space station?

I need someone who pays close attention to detail and communicates back to me, thank you!

1st sheet- is defining keywords in astronomy dealing with the sun. The 2nd section is strictly viewing images that I will upload in order so that it will help you more in that area, the last section is dealing with mathematics. It is ok if you get stuck on a section it is ok to leave it blank. How I will upload it will be in the order you see in the worksheet for example: image 1: WL image 2: CA image 3: HA image 4: Prominence image 5: YK image 6: Eclipse image 7: A1 image 8: A2 And so forth, if you get stuck please message me if you need any additional information. Thank you!

On a blank piece of paper, or an electronic sketch pad, sketch your personal horizon diagram:
write your latitude (include number of degrees and North/South) at the top and the date
represent yourself as a stick figure in the middle
label the compass directions, placing north on the left-hand side of the diagram.

Directions: Given a set of stellar spectra, identify the spectral types for each star.
Part 1: Definitions
Define the following:

Spectra – The spectrum of a chemical element is obtained when we decompose the light it emits into its component colors, making it pass through a scattering element. The spectra of stars are like your fingerprints. By comparing them with known spectra, we can determine their composition.
The spectrum of stars has a thermal origin. Most of them are made up of a bright background, the continuum, whose radiation intensity varies with wavelength according to a law, which can initially be approximated by a black body of the same effective temperature as the star would follow. Absorption lines (dark) and, exceptionally, emission lines (bright) are superimposed on the continuum, emitted by the elements and chemical compounds that constitute the emitting matter, that is, the stellar atmosphere.
When two stars have similar spectra, they also have common physical properties. This facilitates the development of a classification system based on the appearance of the spectra.
The stars are grouped under a letter that symbolizes their spectral type. From the hottest to the coldest, the letters’ sequence is: O – B – A – F – G – K – M. Also, each of these groups is subdivided into ten others, numbered from 0 to 9.

Absorption Line – It is a dark line on a continuous spectrum. It is produced by cold gases that surround hot gases. For example, if the gas is between the detector and the light source -which will generally be a continuous spectrum source- the detector can observe the spectrum of both the gas and the light source. The source will decrease in the intensity of the light observed in the incident photon’s frequency; most of the re-emitted photons will go out in different directions than the original photons had. In this case, an absorption line will be observed.

Fraunhofer Lines – They are a set of dark bands in the solar spectrum. Named after the German physicist Joseph von Fraunhofer who was the first to study them. There are about 570 lines. The prominent bands were assigned the letters from A to K and the thinner ones with other letters.

Emission Lines – They are bright-lines in a specific location of the spectrum radiating material, which corresponds to light emission at a specific frequency. The intensity of the emission lines depends on the number of atoms in each state. For example: If the detector can observe the gas but cannot see the light source, only the re-emitted photons will be observed, resulting in emission lines.

Wein’s Law – It quantitatively expresses the empirical fact that the peak or maximum of emission in the spectrum of a black body shifts towards shorter wavelengths (higher frequencies) as the temperature increases.
When the temperature of a blackbody radiator increases, the overall radiated energy increases. The peak of the radiation curve moves towards shorter wavelengths. When the maximum is evaluated from the Planck radiation formula, the product of the maximum wavelength and the temperature is found to be constant.
This relationship is called Wien’s displacement law. It is useful for determining the temperature of hot radiating objects such as stars, and indeed for determining the temperature of any radiating object, the temperature of which is much higher than that of its environment.

Part 2: Characterizations
Research the following. Find what absorption lines you need to look for in each spectral type-as well as the average temperature for the stars in that spectral type. Write down the absorption lines in nanometers!

Absorption Lines Average Temperature Absorption Lines in Nanometers
O – Purple 28,000 – 50,000 435 – 380 nm
B – Blue 10,000 – 28,000 500 – 435 nm
A – Light Blue 7,500 – 10,000 520 – 500 nm
F – White (no green) 6,000 – 7,500 565 – 520 nm
G – Yellow 5,000 – 6,000 590 – 565 nm
K – Orange 3,500 – 5,000 625 – 590 nm
M – Red 2,500 – 3,500 740 – 625 nm

Part 3: Identify the Spectral Types
Using what you researched from part II, find the spectral type for each star using the star’s absorption spectra below. (HINT: you can use peak temperature AND absorption lines to ID a stellar spectra!)

Create a chart or graphical representation that compares and contrasts the atmospheres of Earth, Venus, Mars, Jupiter, and the Essay

Create a chart or graphical representation that compares and contrasts the atmospheres of Earth, Venus, Mars, Jupiter, and the Essay. Create a chart or graphical representation that compares and contrasts the atmospheres of Earth, Venus, Mars, Jupiter, and the Sun. There are many different chemical and physical properties you can include, so think carefully about what you include and why. What do you think sustains these atmospheres and what is their source or origin? What lessons, if any, can be learned from the different atmospheres in relation to Earth’s atmosphere and its sustainability?

Be sure to review the assignment rubric carefully before you start. Rubric # 3
