When a star becomes a singularity and has zero volume and infinite density, it is called_______________?
Correct answer: C. Black hole
- A. White dwarf
- B. Blue giant
- C. Black hole
- D. Wolf-Raynet star
Explanation
A black hole forms when a sufficiently massive star collapses so strongly that its escape velocity exceeds the speed of light. The zero-volume, infinite-density point is technically the singularity inside the black hole.

About Astronomy and Space
Astronomy covers the structure and motions of the solar system, planets, satellites, comets, asteroids and meteoroids, together with gravity, eclipses, seasons and phases of the Moon. It also introduces stars, galaxies, nebulae, black holes, space telescopes and satellites, while distinguishing rotation from revolution and meteors from meteorites.

This in-between phase of stellar nurseries and star formation in stellar evolution is when the gathered dust is still condensing to form a star.
You have discovered a new celestial body. It has a thick atmosphere and it produces powerful cosmic winds and, when observed, the clouds obscure the body. You have determined it is this type of star.
