2. The Night Sky Success Criteria Today you will:
Know some objects that you can see
in the night sky
Understand the structure of the Universe
Be able to compare the relative sizes of objects in the Universe

3. What is in the night sky?
Think: How many things can you think of that you might be able to see if you looked at the sky tonight? Pair: Compare your list with the person next to you. Can you explain what everything on your list is? Share: How many suggestions do we have from the whole class?

4. What is in the night sky?
The Sky Tonight – National Schools’ Observatory
Tonight’s Sky - Hubble
National Schools’ Observatory gives sky maps; either whole sky or NESW
Hubble site gives monthly video explaining what you can see including planets, stars and constellations (5-6 minutes long) SEE NEXT SLIDE for embedded video of July 2015

9. Milky Way Galaxy You are (approximately) HERE
The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Sagittarius arm of the Milky Way.
You are (approximately) HERE

17. Proxima Centauri (a star)
Final thought – how far?
How far are each of these objects from the Earth? Can you put them in order of distance, starting with the Earth at the centre?
Moon
Proxima Centauri (a star)
Andromeda (a galaxy)
Sun
Neptune

18. Final thought – how far? Moon = 384 000 km Sun = 150 000 000 km
How far are each of these objects from the Earth? Can you put them in order of distance, starting with the Earth at the centre?
Moon = km
Sun = km
Neptune = km
Proxima Centauri =4.0 x 1013 km (4.3 ly)
Andromeda = 2.5 x 1019 km (2.5 million ly)
