Difference between Astronomical object and Galaxy merger

Astronomical object vs. Galaxy merger

An astronomical object or celestial object is a naturally occurring physical entity, association, or structure that exists in the observable universe. Galaxy mergers can occur when two (or more) galaxies collide.

Similarities between Astronomical object and Galaxy merger

Astronomical object and Galaxy merger have 15 things in common (in Unionpedia): Active galactic nucleus, Bulge (astronomy), Cosmic dust, Dark matter, Dwarf galaxy, Elliptical galaxy, Galaxy, Globular cluster, Interacting galaxy, Molecular cloud, Quasar, Spiral galaxy, Starburst galaxy, Stellar evolution, Supernova.

Active galactic nucleus

An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much higher than normal luminosity over at least some portion—and possibly all—of the electromagnetic spectrum, with characteristics indicating that the excess luminosity is not produced by stars.

Bulge (astronomy)

In astronomy, a bulge is a tightly packed group of stars within a larger formation.

Cosmic dust

Cosmic dust, also called extraterrestrial dust or space dust, is dust which exists in outer space, as well as all over planet Earth.

Dark matter

Dark matter is a theorized form of matter that is thought to account for approximately 80% of the matter in the universe, and about a quarter of its total energy density.

Dwarf galaxy

A dwarf galaxy is a small galaxy composed of about 100 million up to several billion stars, a small number compared to the Milky Way's 200–400 billion stars.

Elliptical galaxy

An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless image.

Globular cluster

A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite.

Interacting galaxy

Interacting galaxies (colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another.

Molecular cloud

A molecular cloud, sometimes called a stellar nursery (if star formation is occurring within), is a type of interstellar cloud, the density and size of which permit the formation of molecules, most commonly molecular hydrogen (H2).

Quasar

A quasar (also known as a QSO or quasi-stellar object) is an extremely luminous active galactic nucleus (AGN).

Spiral galaxy

Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae(pp. 124–151) and, as such, form part of the Hubble sequence.

Starburst galaxy

A starburst galaxy is a galaxy undergoing an exceptionally high rate of star formation, as compared to the long-term average rate of star formation in the galaxy or the star formation rate observed in most other galaxies.

Stellar evolution

Stellar evolution is the process by which a star changes over the course of time.

Supernova

A supernova (plural: supernovae or supernovas, abbreviations: SN and SNe) is a transient astronomical event that occurs during the last stellar evolutionary stages of a star's life, either a massive star or a white dwarf, whose destruction is marked by one final, titanic explosion.
