  7. To conclude (or really, begin): 10 11 Suns light 10 2-5 yr old Because light travels at a finite speed, looking far away is looking into the past Nearby galaxies light 10 6+ yr old There are ~100 billion stars in our Galaxy, the Milky Way Gemini Planet Imager There are ~100 billion galaxies in the visible HR 8799 universe Most stars host planets (although mostly uninhabitable by our standards) We are made of stardust Distant galaxies light 10 9+ yr old ASTR/PHYS 1060: The Universe Fall 2018: Midterm 1 Review � 7

  22. The reason it’s two-faced is known, but how that happened is not! The Moon’s crust is thicker on the far side than the near side! Mars-sized protoplanet Theory 1) two proto-Moons formed from collision, which later “gently” coalesced Theory 2) the Moon formed very close to the Earth, became tidally locked soon thereafter, and the heat from the Earth “evaporated” crust on the near side, which preferentially condensed on the cooler far side http://www.slate.com/blogs/bad_astronomy/2014/07/01/ proto-Earth the_moon_s_two_faces_why_are_they_so_different.html ASTR/PHYS 1060: The Universe Fall 2018: Chapter � 22

  26. Newton’s 3 Laws 1) Law of Inertia: Objects at rest stay at rest, objects in motion stay in motion (Galileo figured this one out) 2) Motion is changed by unbalanced forces acceleration = force / mass 3) Forces always come in pairs and those pairs are always equal in strength but opposite in direction ASTR/PHYS 1060: The Universe Fall 2018: Chapter 3 � 26
