Across
- 1. An extremely bright and distant active galactic nucleus powered by a supermassive black hole at its center.
- 3. Galaxy A type of spiral galaxy with an exceptionally bright nucleus, believed to contain a supermassive black hole.
- 8. Galaxy A galaxy with a lens-shaped disk but lacking the prominent spiral arms of a typical spiral galaxy.
- 11. Galaxy A galaxy without a distinct, regular shape, often exhibiting a chaotic appearance with irregular structures.
- 13. Galaxy A galaxy with a ring-like appearance, formed by the collision or interaction with another galaxy.
- 14. Galaxy A galaxy experiencing an exceptionally high rate of star formation, leading to intense and widespread starbursts.
- 15. Galaxy A galaxy that has merged with and absorbed one or more other galaxies, leading to complex structures and features.
Down
- 2. Galaxy A galaxy characterized by its spiral arms, containing a central bulge and a rotating disk of stars, gas, and dust.
- 4. Galaxy A galaxy with an elliptical shape and a smooth, featureless appearance, containing older stars and less gas.
- 5. Diffuse Galaxy A faint and low-surface-brightness galaxy with an unusually large size given its low luminosity.
- 6. Galaxy A galaxy with a highly energetic nucleus, often emitting more radiation than the combined light from its stars.
- 7. Galaxy A type of irregular galaxy, often small and faint, similar to the Magellanic Clouds that orbit the Milky Way.
- 9. Spiral Galaxy A spiral galaxy with a central bar-shaped structure connecting the spiral arms, enhancing star formation.
- 10. Galaxy A galaxy with unusual or irregular features, often resulting from gravitational interactions with other galaxies.
- 12. Galaxy A small galaxy, often containing fewer stars and less mass compared to larger galaxies like the Milky Way.
