Astronomers Trivia Questions
1. The Nobel Prize in 1993 was awarded for a joint discovery, made by Joseph H. Taylor Jr. and Russel A. Hulse. What was the discovery?

From Quiz Astronomers

Answer: The first binary pulsar

Joseph H. Taylor Jr. was a radio astronomer and physicist. He studied at Haverford College and got his PhD in Astronomy at Harvard University in 1968. Russel Alan Hulse, a former student of Mr. Taylor's, studied at Cooper Union College in New York and went on to get his PhD in physics from the University of Massachusetts. -Stampede_Gal

2. When Clyde outgrew his small 2 1/4 inch (lens diameter) telescope, what did he do?

From Quiz Clyde Tombaugh

Answer: made his own telescope

He eventually built additional telescopes, around thirty. He also ground his own mirrors for the telescopes. Most people today buy the mirrors already done and just build the rest of the scope.

3. Who identified the first white dwarf star?

From Quiz Early Astronomers Three

Answer: Walter Sydney Adams

He identified Sirius B as the first white dwarf. Minor Planet 3145 Walter Adams is named after him as is a Lunar crater.

4. Who managed to compile the first known star atlas?

From Quiz Early Astronomers Two

Answer: Hipparchus

Hipparchus devised the magnitude system as well. He lived from 190 B.C. to 120 B.C.

5. Who discovered the moons of Jupiter in 1610?

From Quiz Early Astronomers One

Answer: Galileo

The four largest satellites of Jupiter, Io, Europa, Ganymede and Callisto, would all be visible to the unaided eye (at night) if Jupiter was not in the way.

6. During the 3rd Century B.C., the Earth's circumference was estimated to be 25,000 miles (a rather close estimate) by:

From Quiz Historical Cosmologists

Answer: Eratosthenes

Eratosthenes used the angle on the sun in the sky over Syene and Alexandria at noon (calculated based on the distance between the cities). Posidonius tried the same thing, but used Rhodes and Alexandria. Unfortunately, he had the wrong distance between the 2 cities. Ptolemy used Posidonius' erroneously small circumference in his geography treatise (a document which influenced Christopher Columbus). Hipparchus, though a great astronomer, is not known for this feat.

7. What radical theory did Copernicus propose in his book "On the Revolutions of the Heavenly Spheres"?

From Quiz Astronomers

Answer: That the Earth and the other planets orbit the Sun

Nicolaus Copernicus was born in 1473 and died in 1543. Uncomfortable with Ptolemy's views of the universe, he proposed the heliocentric model of the universe thereby placing the sun in the center of the solar system. Copernicus started work on his radical theories early in the 16th century but the book itself was not published until just prior to his death. Initially there was little opposition by the church to the book, partly because it was not widely distributed. The views promoted by Copernicus would greatly influence Galileo a century later. -StetsonHat

8. Clyde Tombaugh originally made sketches of what?

From Quiz Clyde Tombaugh

Answer: Mars and Jupiter

From Quiz Early Astronomers Two

Answer: Harlow Shapley

11. Who discovered the division in the rings of Saturn?

From Quiz Early Astronomers One

Answer: Cassini

In 1838, Friedrich Bessel measured the tiny displacement, or parallax, of a nearby star relative to the more distant stars throughout the progress or a year.

From Quiz Historical Cosmologists

24. Which astronomer compiled a catalogue of nebulae, clusters and galaxies in the late 18th century?

From Quiz Astronomers

Answer: Charles Messier

Messier was fascinated by comets having seen one when he was 14. As his studies in astronomy continued, his methodical ways of recording his observations allowed him to create the catalogue. In his observations he found that non-stellar objects, such as nebulae, sometimes look like comets. For this reason, he began to catalogue the objects positions. -Stampede_Gal
