quasar etymology

Etymology:

The word "quasar" is a portmanteau of "quasi-stellar" and "radio source."

Meaning:

A quasar is a type of luminous celestial object that is extraordinarily distant and emits vast amounts of energy. They are among the most energetic and distant objects in the universe.

Origin:

• Quasi-stellar: In the 1950s, astronomers used the term "quasi-stellar" to describe faint, star-like objects that exhibited redshift similar to galaxies but were much brighter.
• Radio source: In the 1960s, astronomers discovered that many of these quasi-stellar objects were also strong radio источники.
• Quasar: In 1963, the astronomer Maarten Schmidt recognized that these quasi-stellar radio sources were unusually luminous and suggested the name "quasar."

Additional Notes:

• The plural form of "quasar" is "quasars."
• Quasars are powered by massive black holes at their centers, which accrete surrounding gas and release enormous amounts of energy.
• They are typically billions of light-years away and can be observed as bright, point-like objects through telescopes.
• Quasars play a crucial role in astrophysics, as they provide insights into the early universe, black hole formation, and galaxy evolution.
