Context

• Blazar 3.5 billion light-years from Earth provides better understanding of physics powering their massive optical fare.

About

• Blazars are one of the most luminous and energetic objects in the universe powered by material falling onto a super-massive black hole at the center of the host galaxy – the luminosity being because of their a jet composed of ionized matter traveling at nearly the speed of light towards an observer (the Earth).
• While their brightness varies in the long duration, they maintain their brightness levels in short duration.
• Blazers are among one of the most favorite astronomical transient objects, and their study could provide clues to the processes happening close to the black hole, not visible through direct imaging.
