Explanations: answer key for all 10 questions
- Q1: Which is the brightest star in the night sky?
Answer: Sirius
Sirius, in the constellation Canis Major, is about 8.6 light-years away. Its name comes from the Greek word for glowing.
- Q2: Why is Polaris useful for navigation in the Northern Hemisphere?
Answer: It sits almost directly above Earth's North Pole
Polaris stays nearly still while other stars circle around it. It is actually only about the 48th brightest star.
- Q3: What is the nearest large spiral galaxy to the Milky Way?
Answer: The Andromeda Galaxy
Andromeda is about 2.5 million light-years away. It can be seen with the naked eye on dark nights.
- Q4: What did Galileo discover orbiting Jupiter in 1610?
Answer: Four large moons
Io, Europa, Ganymede and Callisto are called the Galilean moons. They showed that not everything orbits Earth.
- Q5: Edwin Hubble's observations in the 1920s showed that the universe is doing what?
Answer: Expanding
Hubble found that distant galaxies are moving away from us. This became key evidence for the Big Bang theory.
- Q6: What does a light-year measure?
Answer: Distance
A light-year is the distance light travels in a year, about 9.46 trillion kilometers. It is used because space distances are so huge.
- Q7: Betelgeuse in Orion is what type of star?
Answer: A red supergiant
Betelgeuse is so large that it would reach past the orbit of Mars if placed where the Sun is. It will one day explode as a supernova.
- Q8: The James Webb Space Telescope mainly observes in which kind of light?
Answer: Infrared
Infrared light passes through dust and shows very distant, early galaxies. Webb launched on December 25, 2021.
- Q9: In 2019, scientists released the first image of a black hole in which galaxy?
Answer: M87
The Event Horizon Telescope linked radio dishes around the world. An image of the Milky Way's black hole followed in 2022.
- Q10: What is the closest star to the Sun?
Answer: Proxima Centauri
Proxima Centauri is about 4.2 light-years away. It is a small red dwarf with at least one planet.
Bing Astronomy Quiz – Stars, Galaxies and Night Sky Facts
Astronomy is one of the oldest sciences. People have studied the night sky for thousands of years to track seasons, navigate and understand our place in the universe. Modern telescopes now reveal details our ancestors could only imagine.
Bright stars make good starting points. Sirius is the brightest star in the night sky, Polaris marks north and Betelgeuse in Orion is a red supergiant that will one day explode. The nearest star to the Sun is Proxima Centauri, about 4.2 light-years away.
Discoveries changed how we see the cosmos. Galileo spotted four moons orbiting Jupiter in 1610, and Edwin Hubble showed in the 1920s that galaxies are moving away from us, meaning the universe is expanding. The Andromeda Galaxy is our closest large neighbor.
Today's tools go even further. The James Webb Space Telescope studies infrared light from the earliest galaxies, and the Event Horizon Telescope produced the first image of a black hole in 2019.
Ten questions, three options each and 150 seconds on the clock: that is the challenge of the Bing Astronomy Quiz. Read every question carefully, because some answers are designed to look right at first glance. The explanation after each answer shows the reasoning, and you can play again to improve your score.
