Quasar 3C 273

What is a Quasar

• Quasi-stellar-object short: Quasar

• is the core of an active galaxy

• in visible light: looks like a star (brightest objects)

• 10^12 times brighter than the sun

• it emits two jets of ionised GAAAAAAAS

• very bright

• characteristic spectra

• very bride emission lines

3C 273

• discovered 1963

• by Marten Schmidt
