This site is intended for students age 14 and up, and for anyone interested in learning about our universe. ... The discovery of quasars was really spread over time. Quasar is a shortening of "quasi-stellar radio source", and they've also been called quasi-stellar objects or QSOs.

･ They are ordinary stars located at vast distances from Earth. ･ Like stars visible in our night sky, quasars reside within the boundaries of the Milky Way. ･ Their spectra strongly resemble the spectra of stars. ･ They look like stars on ...

The assumption was that they were stars, and yet their optical spectra were unlike those of any star previously observed. They were called quasi-stellar objects, and are now generally called QSOs or quasars.

Quasars detected as radio sources are called radio quasars or quasi-stellar sources (QSSs). For every QSS there are perhaps about 100 radio-quiet quasars called quasi-stellar objects (QSOs) or quasi-stellar galaxies (QSGs), which are detected by other means.

The general belief is that these strange objects represent one of the possible final stages of a star that has a mass at least ten times greater than that of the Sun. However, the most massive black holes can only be found in so-called 'quasars' or Quasi Stellar Radio Sources which, during the interaction between the...

The first quasars were discovered with radio telescopes in the late 1950s.Quasars are also called quasi-stellar objects, or QSOs, which means that they may look like stars but they are not. A typical quasar produces more light each second than an entire galaxy of stars.

At first, after recognizing this property, scientists called quasars "quasi-stellar radio source", but then they shortened the name to just quasars ("Quasar" 1). ... Called the Einstein cross, this theory states that a quasar emits energy through a high mass galaxy and the galaxy, acting like a mirror or a lens,

Quasars, also called Quasi-Stellar-Objects because of their apparently stellar aspect, were discovered in 1963. They are very bright and compact objects, in fact the brightest objects in the Universe. After having long been considered as mysterious objects, they are now identified as cores of active galaxies.
