blazar
/ˈbleɪzɑː
/noun Astronomy
A type of quasar that is an intense, irregularly variable source of highly polarized light, thought to arise from a plasma jet pointing in the direction of the earth: at the blazar’s heart is a supersized black hole with a mass millions to billions of times that of the sun...
- In this study, the researchers focused on distinctive galaxies called blazars, which are several billion light years away.
- To match the amount of energy given off by a typical blazar in one second, the sun must shine for 317,000 years.
- What makes a blazar so bright is that one of these particle jets happens to be aimed almost straight at us.
Origin
1980s: from blaze1, on the pattern of quasar, with bl- echoing the name BL Lac object.
