Congrats to all who played. When you get the first correct answer to one of my questions, you are a winner. I usually have between five and ten trivia questions per contest.

To the winners go Eternal Glory, World-wide declaration of their victories (on my blog), and an Opportunity to double their impact of making the world a better place.

  1. One percent…..… @joelschultz:  Early galaxies were not only much smaller, but had almost no heavy metals, especially oxygen. These early galaxies had not been around long enough for the most massive stars to go supernova and spread metals into the interstellar reaches. How long does it take fr a galaxy to form?


  1. Harlow Shapely…….. @1JohnnyBoy: Used the period-luminosity law to calculate distance to clusters. Who came up with the period-luminosity law?

  1. Nine pounds per second………@rossm3838: As the Earth plows thru space, a lot of small rocks and pieces of ice fall into out atmosphere. At the beginning of the space race NASA decided to discover what was out there.

  1. Sagittarius…………….@joelschultz: That’s why that body is called the Sagittarius Dwarf Elliptical Galaxy,


  1. The Large Magellanic Cloud (LMC).……….. @joelschultz: Irregular galaxy that orbit the Milky Way Galaxy. The Local Group is at least 31 confirmed galaxies.

  1. Fifty (50) ………….. @FuzzyPandiest:   Earth has a diameter of a little more than 12,000 km. Our Moon has a diameter of almost 3,500 km. Then calculate the volumes using V = 4/3 πr³ and compare.

  1. Tucana…………@WussisWuss: The Small Magellanic Cloud also orbits the Milky Way Galaxy.


  1. Andromeda……………. @sgosink:: The Andromeda Galaxy is in the constellation Andromeda.
