Question

Quizplus · Accepted Answer

Quasars are the most distant active galaxies known to us. They are located at extreme distances and emit massive amounts of energy, making them visible across vast areas of space. Some quasars have been observed to be billions of light years away from us, indicating that they existed at a time when the universe was much younger. Quasars are the most distant and luminous active galactic nuclei known. They emit prodigious amounts of energy across the entire electromagnetic spectrum, powered by accretion of matter onto supermassive black holes at the centers of their host galaxies. Observations have revealed quasars at redshifts greater than 7, corresponding to lookback times of more than 13 billion years, only about 800 million years after the Big Bang.
