Across
- 2. Astronomical tool that gathers light from distant space objects to make them appear larger, brighter, and closer
- 5. A specialized building or location equipped with telescopes and other scientific instruments to study stars, planets, and other objects in space
- 7. Smallest individual data point on a digital camera sensor or an astronomical image
- 10. A piece of curved, transparent material (like glass) or a massive cosmic object that bends and focuses light to create a clearer, magnified image of distant celestial bodies
- 11. The smallest angle between two close objects that a telescope can still see as two separate things instead of one blurred blob
- 14. Optical instrument that uses a curved primary mirror to gather and focus light from distant space objects
- 15. Optical instrument that uses a glass lens to bend and focus light to create a magnified image of distant objects
Down
- 1. Technique of measuring the brightness, or intensity of light, coming from celestial objects like stars, planets, and galaxies
- 3. Light-sensitive microchip used in digital cameras to turn starlight and other cosmic light into computer images
- 4. The separation of light into its different colors or wavelengths
- 6. Total surface area of a telescope's primary mirror or lens that gathers light from space
- 8. Telescope design where light reflects off the primary mirror and converges at a single focal point directly in front of the mirror, without bouncing off any secondary mirrors
- 9. The bending of light from stars and planets as it passes through Earth's atmosphere
- 12. Scientific term for the twinkling or shimmering of stars
- 13. Technique that combines light or radio waves from two or more separate telescopes to act like one giant virtual telescope
