- 3. Small rocky or metallic objects that orbit the sun, primarily found in the asteroid belt between Mars and Jupiter.
- 7. The common name for a natural light display in Earth's northern region caused by the interaction of charged particles from the Sun with the Earth's magnetic field, creating colorful, dancing lights in the sky.
- 8. A vast collection of stars, planetary systems, gas, dust, and dark matter bound together by gravity, forming a distinct structure within the universe.
- 9. A celestial object composed of dust, rock, and ice that orbits a star and displays a characteristic tail when it approaches the star.
- 12. A powerful explosion that occurs when a star reaches the end of its life cycle, briefly outshining an entire galaxy.
- 13. A massive star in the late stages of its evolution, characterized by its enormous size and reddish appearance.
- 14. A small, dense, and dim remnant of a star that has exhausted its nuclear fuel and is cooling down.
- 18. It's the only planet with a reliable supply of liquid water.
- 19. The total amount of energy radiated by a celestial object, such as a star, per unit of time.
- 22. The scientific study of celestial objects and phenomena in the universe, such as stars, planets, galaxies, and cosmic events.
- 24. A sudden and intense burst of energy and radiation from the Sun's surface, often accompanied by solar storms.
- 25. A luminous celestial object primarily composed of hydrogen and helium that emits light and heat through nuclear fusion, which occurs in its core, providing the energy that sustains it.
- 26. Often called a "shooting star" this rock burns up in Earth's atmosphere
- 28. This planet's retrograde rotation gives it unusual sunrise and sunset directions.
- 31. A fragment of rock and metal that survives its journey through Earth's atmosphere and reaches the planet's surface.
- 33. A large, looping structure of hot, glowing gas that extends from the Sun's surface into its outer atmosphere.
- 34. The curved path followed by an object as it revolves around another, often due to gravitational attraction.
Down
- 1. A large celestial body that orbits a star (typically a sun), is spherical in shape, and has cleared its orbital path of other debris.
- 2. A super-dense remnant of a massive star's core left behind after a supernova, primarily composed of neutrons.
- 4. Dark, cooler areas on the Sun's surface caused by intense magnetic activity and associated with lower temperatures.
- 5. An extremely compact and gravitationally intense region in space where nothing, not even light, can escape its pull due to the immense gravitational force.
- 6. Home to Olympus Mons, the solar system's largest volcano.
- 10. The measure of an object's brightness as observed from a specific vantage point, typically from Earth.
- 11. The intrinsic brightness of a celestial object, especially stars, as observed from a standard distance of 10 parsecs.
- 15. This planet boasts the solar system's fastest winds, reaching up to 1,500 mph.
- 16. An object that orbits a larger celestial body, such as a natural moon orbiting a planet or an artificial satellite in Earth's orbit.
- 17. A vast cloud of gas and dust in space, often the birthplace of stars and planetary systems.
- 20. It rains diamonds on this gas giant due to the immense pressure and carbon-rich atmosphere.
- 21. Known as the "sideways planet" for its extreme axial tilt of about 98 degrees, causing unique and extreme seasons.
- 23. Extreme temperatures make this planet the hottest and coldest in the solar system.
- 27. A late-stage star in which hydrogen fusion has ceased in its core, causing it to expand and become reddish in color.
- 29. The entirety of space, time, matter, and energy that encompasses all galaxies, stars, planets, and everything in existence.
- 30. This gas giant is famous for the Great Red Spot.
- 32. A young, developing star in the early stages of its formation, characterized by gravitational contraction and nuclear fusion initiation.
