Trivia Trap

AstroFest

By Alex Koury

Last month’s big trivia winner was Hannah Adams! Congratulations on a successful submission, Hannah. For the rest of our readers, if you’re so inclined, take a look at last month’s post, which is now updated with all of the correct answers. Also, best of luck to all entrants this month. Keep your eyes on that ¥1000 prize!

When I was still studying astrophysics in college, I always looked forward to July, which was when my University’s Astronomy Department would open up Davey Lab to the public for AstroFest. Visitors would have the chance to peer through the high-powered telescopes on the roof, sit in on planetarium shows, and learn about the wonders of the cosmos.

As you probably well know, Japan has a celestial festival of its own during the month of July: Tanabata, or the Star Festival. It’s a time for making wishes and celebrating the cosmic story of some—literally—star-crossed lovers: Orihime and Hikoboshi.

With that being said, I think you can see where this month’s trivia questions are headed…

Let’s dive right in!

  1. The lovers in the Tanabata mythology are embodied by the stars Vega and Altair. These two stars are part of a readily visible asterism. What is the name of this asterism, and what is the third bright star that comprises it?
  2. It wasn’t until 1992 that the first exoplanet was confirmed to exist. Now, there are over 3,700 known exoplanets, largely thanks to a space observatory named after a famous historical astronomer. That astronomer is most famous for discovering which astrophysical laws that also bear his name?
  3. Effective temperature and color index are among the most basic and useful ways to classify stars. What’s the mnemonic commonly used to easily remember these stellar classes from hottest to coldest?

Answers!

  1. The asterism is known as the summer triangle, and the third bright star of this triangle is Deneb.
  2. The Kepler Space Observatory is named after the astronomer Johannes Kepler who discovered Kepler’s Laws of Planetary Motion.
  3. The basic stellar classes from hot to cold are O B A F G K M, and the most commonly used mnemonic to remember them is Oh, Be A Fine Girl/Guy. Kiss Me! Here are a few more less common but hilariously awesome options:
                          “Overseas broadcast: A flash! Godzilla kills Mothra!”
                          “Only bald Americans feel good kissing mimes.”
                          “Old Bob Always Favors Green Ketchup More.”
                          “Only Boring, Astronomers Find Gratitude Knowing Mnemonics.”

As always, use any means necessary to find the answers to the questions. Send your answers to goodmorningaomori@gmail.com. Answers are due by Friday July 20th! The winner will be announced in the August Vol 1 issue of Good Morning Aomori.
