Welcome to Astronomy!  Here are a couple of links to get you started:

Rare Solstice Lunar Eclipse Dec. 21-22

posted Dec 21, 2016, 8:23 AM by Tom Erekson_lphs

"Tonight, two astronomical events will combine to create a truly rare occurrence. The winter solstice occurs tonight — or tomorrow morning, depending on where you happen to live — meaning that it’s the longest night of the year. Combine that with a lunar eclipse, which only occurs a few times per year, and you have the recipe for one of the longest, darkest nights that any living human has had the opportunity to witness. This rare combination hasn’t occurred since 2010, and before that it hadn’t happened in nearly 400 years, so it’s pretty special."

The best time to catch a brief look at the eclipse itself would be around 1:17 a.m. Utah time, as the moon will be completely behind the Earth and should have a nice reddish glow.

Quizlet to help study constellations

posted Dec 7, 2016, 7:39 AM by Tom Erekson_lphs

Click here to join my Quizlet class, where I created flash cards to help you learn the constellations. A couple of them have images that may not exactly resemble the asterisms as we learned them (Hercules & Perseus, for example), and a couple did not have images in the library, so I did my best to "draw" them using text characters (Boötes & Cancer).

But for the most part, this should help you review your constellations and bright stars.

Extrasolar Planets

Watch this video: 


Now help discover NEW extra-solar planets.

Now, let's learn a little about extra-solar planets that have already been discovered.  

  - On the right you can filter results to see different types of exoplanets, how they were discovered, etc.  Look at one or more of each type of exoplanet:  Gas Giant, Ice Giant, Super-earth, and Terrestrial.
  - For each of these planets, make a comparison between that planet and the star it orbits, and the Sun and planets in our solar system. 
- Switch from "Planet View" to "System View".
- Switch from "Single System" to "Compare to our Solar System"
- How does the planet compare to planets in our solar system in terms of its orbit and mass?

- You will not be turning anything in.

Assignment #1:  Create a Fact Sheet about your Solar System object(s).

Fact Sheet:

1. Is it a gas giant or a rocky terrestrial?  (What is it made of?)

2. Does it have moons?  Name them (or name the largest ones).

List any interesting facts about its moon(s).

3. Does it have an atmosphere? What is it made of?

4. What color does it appear?

5. Does it have rings?  What are they made of?

6. What is its average temperature?

7. How far is it from the sun?

8. Is it a planet, dwarf-planet, or other type of solar system body?

9. How did it get its name?  What does its name mean or signify?

10. Who discovered it and when?

11. Have humans or human-made objects traveled to, by, or on it?  Which missions, and when?

12. What is its diameter?

13. How long does it take to rotate on its axis?

14. How long does it take to orbit around the sun?

15. How much would you weigh on this object?

16. Does it have any mountains or valleys? Name some of the major ones if they do.

17. Anything else interesting about your object, please include it.

18. List three unique facts we should know about this object that might become test questions.

Assignment #2:  Create a Google Slides presentation about your solar system object.  Include images.  Use the Fact Sheet as a guide for what you should include in the presentation.  The last slide should list your sources.
