Astronomy Quiz
Explore the universe through 90 questions on the solar system, stars, galaxies, and space exploration. Three difficulty levels to test your astronomy knowledge.
Astronomy Quiz: Explore the Universe While You Play
This astronomy quiz offers 90 questions to take you from the solar system to the farthest reaches of the universe. You'll discover the eight planets and their moons, stars and their life cycles, distant galaxies, and mysterious black holes. Every question has been checked against reliable scientific sources. This quiz is part of our science quizzes category, which brings together all our questions on scientific subjects.
From the Solar System to Distant Galaxies
The easy questions cover the basics: the order of the planets, the name of our galaxy, the first steps on the Moon. The medium level takes you further with space telescopes like Hubble, supernovas, and Jupiter's Galilean moons. On hard mode, you'll face advanced concepts: the Tolman-Oppenheimer-Volkoff limit, the spectral classification of stars, the discovery of the first exoplanet. Plenty to satisfy the curious and astrophysics enthusiasts alike.
Stars, Black Holes, and the Big Bang
Astronomy isn't limited to planets. You'll be quizzed on the life cycle of stars, from their birth in nebulae to their death as white dwarfs, neutron stars, or black holes. The questions also cover the cosmic microwave background, a remnant of the Big Bang, and the space missions that have mapped the universe: Planck, Hubble, James Webb. Space exploration, from Neil Armstrong to the New Horizons probe, plays a major role.
Try the Chronological Format
Looking to mix things up? Our chronological quiz challenges you to put events in the right order. It's perfect for memorizing the key dates of space exploration: the first artificial satellite, the first human in space, the first moon landing, the launch of the Hubble Space Telescope.
