Across
- 2. : The force that allows stars and planets to orbit each other
- 4. : Wavelength compresses when a star moves toward us
- 6. : A telescope that scans nearly the entire sky for exoplanets
- 7. : The precise measurement of a star’s position to detect orbital wobbles
- 11. : This effect causes light to shift toward red or blue when an object moves
- 14. : A layer of gases that surrounds a planet
- 17. : Distance between light wave peaks, affected by Doppler shift
- 18. : NASA telescope that found exoplanets using the transit method
- 19. : A graph showing a star’s brightness over time
- 23. : What astronomers measure to detect dips in starlight
- 25. : A method that captures actual images of exoplanets by blocking starlight
- 26. : A small version of a gas giant, larger than Earth
- 27. : Planet larger than Earth but smaller than Neptune

Down
- 1. : A method where a planet passes in front of its star, dimming its light
- 3. : Nickname for the habitable zone—not too hot, not too cold
- 5. : A planet orbiting a star outside our solar system
- 8. : A planet not orbiting any star, floating freely through space
- 9. : An instrument that blocks starlight inside the telescope to see planets
- 10. : Short wavelength light, part of the electromagnetic spectrum
- 12. : Used in microlensing, like focusing light through a magnifying glass
- 13. : Light spread into wavelengths to analyze planet atmospheres
- 15. : A planet completely covered in oceans
- 16. : Method that uses a planet's gravity to bend light from a distant star
- 17. : The small motion of a star pulled by a planet’s gravity
- 20. : Occurs when one celestial body blocks light from another
- 21. : Long wavelength light, often used in exoplanet detection
- 22. : The region where temperatures allow liquid water to exist
- 24. : A device that blocks starlight before it reaches the telescope
- 28. : Wavelength stretches when a star moves away from us
