## SETI Communication Short Response

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.

## astronomy lab

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

its really not a lot of work if you scroll down to #4 in the lab you will see that google slides calculates most of the calculations for you!!
all explained in attached lab document thank you!

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!

## Lab

Complete all the steps and calculations, and fill in each of the blanks that appear on questions #1 – 10

## Astronomy Question

1. The TESS observatory is adding new data and understanding to the search for extrasolar planets. Review the following graphs of transit data from TESS (and other observatories) and explain in your own words what the curve represents, answering the questions below .
What do the black dots represent?
What causes the dip in the center of each graph?
Why are the dips different shapes?
What is the difference between a narrow dip and a wide dip?
What is the difference between a shallow dip and a deep dip2. “K2-315 b is a terrestrial exoplanet that orbits a M-type star. Its mass is 0.809 Earths and it takes 3.1 days to complete one orbit of its star.”Explain the above sentence in your own words, as if you were talking to a 8 year old. Keep it very simple and understandable to someone without knowledge in this area.
3. When was the first extrasolar planet discovered and what method did they use?
