1. We'll start with an easy question. The first telescope to be used for astronomy purposes by Galileo Galilei was which kind of telescope?

Answer: refractor

2. To astronomers anything that interferes with observing, such as smog, fog, and dust, is called what?

Answer: sky pollution

3. The word gibbous(used to describe the moon during the waxing and waning phases when more than half of the moon can be seen) is a Middle English word meaning what?

Answer: bulging

Bulging is a good description of the moon's shape between it's quarter phase and full phase.

4. The reflecting telescope was first built by what Scotsman?

Answer: James Gregory

James Gregory first built his reflector in 1663, 5 years before Newton built his. Isaac Newton gets the credit for inventing it,however, because his design is the one that caught on. (If you didn't know, Guillaume Cassegrain and Charles Messier were French.)

5. What is the angular size of the moon?

Answer: All of the other answers are correct

Half a degree, 30 arcminutes, and 1800 arcseconds are all equivalent.

6. One parsec is equal to what?

Answer: 206,265 A.U.

That is the distance from the sun a star must be to show a parallax of one arcsecond.

7. A star of spectral class B has a surface temperature of what?

Answer: 10,000-28,000 K

Spectral class B stars are the second hottest stars. The only thing hotter is a class O star.

8. Who is considered to be the father of radio astronomy?

Answer: Karl Jansky

The basic unit of radio brightness, the Jansky (Jy), is named after him.

9. The famous Perseid meteor shower is well known. A lesser known fact is the comet it orginates from. What is the parent comet of the Perseids?

Answer: 1862III (Swift-Tuttle)

Comet Encke is the parent comet of the Beta Taurids, Halley is the parent comet of the Orionids, while 3200 Phaeton produces the Geminids.

Answer: Leonids

The last time that happened was last year. So if you missed them (like me) and hope to see them next time (like me) you have a 32-year wait until 2032. By then I'll be 45.
