Question

besides stars and planets, what other astronomical objects can be found in the universe?

Explanation:

The problem is about identifying astronomical objects in the universe besides stars and planets, which falls under Natural Science, specifically Physics (Astronomy subfield). Astronomical objects include moons (natural satellites), asteroids, comets, nebulae, galaxies, black holes, quasars, and interstellar dust/gas. Moons orbit planets, asteroids are rocky bodies in the asteroid belt, comets have icy cores with tails, nebulae are gas/dust clouds, galaxies are collections of stars, black holes have intense gravity, quasars are active galactic nuclei, and interstellar matter fills space between stars.

Answer:

Besides stars and planets, other astronomical objects in the universe include moons (natural satellites), asteroids, comets, nebulae, galaxies, black holes, quasars, and interstellar dust and gas.
