The SETI (Search for Extra Terrestrial Intelligence) radio telescopes have picked up several unusual radio transmissions from deep space. The analysis of the signals support the conclusion that the transmissions originated from intelligent life in a distant solar system. You would like to establish communication with this life-form, and you must decide both the message you will send and the kind of communication you will use (digital, music, language, etc.). Defend your choice. [Note: this is a FICTIONAL scenario]
A few sentences is fine, a few paragraphs at the most.
sheet with speed and distance data for your sample of galaxies.
sheet with final version of data and Hubble plot.
Lab with calculations done and questions answered answers can be very brief but questions at end must be answered in complete sentences
Merge your data to the Hubble’s Law Lab Workbook below. ONLY copy data for the galaxies listed. When completed in google docs it should generate your graph for you. Let me know if it does not. all explained in attached lab document thank you!
Explore the internet (or books or magazines) to find your favorite image related to astrobiology. Then:
Write a short paragraph (3-4 sentences) stating the science content of the image. Specifically, explain (i) what the image is about, and (ii) how the image is connected to astrobiology (not just astronomy or biology). How is it related to what we’ve been learning in this course? If it is an astronomy image, like a Hubble Space Telescope image of a galaxy or nebula, make sure you explain the connection to life: How is the image related to the origin, evolution, or search for life?
Then in a second paragraph, very briefly explain why you chose the image (2-3 sentences is fine).
Obviously, include the image in your assignment (put it at the start). Be sure to fully cite the source of the image (URL) and give proper credit to whoever created the image. Put this right at the top of your homework. Be sure to run a spelling checker on you document to make sure you don’t lose points for typos and dumb things like that
total 6 sentences
Complete all the steps and calculations, and fill in each of the blanks that appear on questions #1 – 10
There are very considerable obstacles that stand in the way of interstellar travel, mostly relating to the nearly unimaginable distances between the stars. As a consequence, it seems very unlikely that we will ever be able to travel efficiently to and between the stars, or conversely that we will be or have been frequently visited by ETs from home planets around other stars.
If contact is ever to be made, it is more likely to be in the form of interstellar communication via radio signals or some equivalent. The vast distances and consequent travel times for the signals and messages will, however, necessarily constrain the ‘conversations’ and information flow between us and any ET; but knowledge of their presence, once established, will be forever with us.
In light of these considerations, it is arguably unnecessary to fear (as some people do) that any ET who learns of our existence will swiftly swoop down to plunder or enslave us (a common theme in science fiction stories). Nevertheless, it is certainly true that profound effects on our societies and our perception of ourselves would follow our learning of the existence of extraterrestrial intelligences comparable to (or vastly more advanced than) our own.
With that in mind, please discuss two aspects of this issue:
If and when such a discovery is made, how do you believe it should be handled? Does human society have the capacity to absorb this kind of information without calamitous consequences, or should there be some mechanism for gently conditioning the general public to the new reality? If so, how and by whom?
How do you imagine that such information would affect your own human perspectives? If you are religious and comfortable with doing so, you may choose to comment on that particular aspect of the discovery, but discussions in much more general terms and contexts are welcome and encouraged.
Make sure you not merely stating your opinion, but use evidence/s and justifications to support your claim/s.
Your posts should be about one page long.
Please do article 2! Will be uploading files.

“Your Inner Fish”
This homework explores the deep connection between all life on Earth, but in a very specific and relevant way: it is about ourselves. The PBS documentary Your Inner Fish by Dr. Neil Shubin examines the remarkable connections between all vertebrate life (animals with backbones). From fish to felines, from to gerbils to giraffes, from hummingbirds to humans – we have very similar genetics and anatomy. Please watch this documentary available at these sites:
Then in four sentences tell me (i) something that you learned, and (ii) something that you liked (or disliked) about the documentary (e.g. what was your favorite part? Least favorite part?). That’s it – no more than four sentences please. This is a pretty easy assignment, but a very valuable one, now that we understand the common threads running thought all of terrestrial biology.
Be sure to give your name, a title, and the date at the start of your answer, and a bibliography reference to the video.
Consider the following discussions and write a minimum 3 sentence response to each discussion
1. Suppose we wanted to send a satellite to orbit Pluto at 40 AU away from the Sun to measure the parallax of stars…describe at least 3 advantages and 3 disadvantages of measuring parallax with a satellite near Pluto versus measuring parallax with a telescope on Earth’s surface.
2. We have encountered objects that have entered our solar system from other solar systems (‘Oumuamua is one famous example…feel free to research this object if you have never heard of it before). What if our solar system encountered another star today…what would happen to the Sun in that scenario? Would the Earth survive such an encounter? Why or why not?
3. What if the Sun had been born in a tertiary (3 star) system…do you think the Sun would have evolved to be a G star like it is now or would the Sun have evolved into a different type of star? How would planets form in such a system? Where would the habitable zone be located approximately (or would there be one)?
By Thursday 11/4 at 11:59 P.M., please reply to at least two of your classmates’ posts with practical suggestions or thoughtful comments on their posts. Please follow the rules and regulations of netiquette as well as the rules for replying to your classmates’ posts.
Is Pluto a planet? What’s your opinion on the
matter? Note, you don’t have to argue whether or not it passes the
rules set down in 2006. We’ll take it as a given that it doesn’t. This
is more about what you think about those rules.
Nothing will be settled here, but it’s still fun to talk about it!
