1. Astronomers have discovered the oldest
supermassive black hole ever found—a behemoth that grew to 800 million times
the mass of the sun when the universe was just 5 percent of its current age, a
new study finds.
2. This newfound giant black hole, which formed just 690 million years after the Big Bang, could one day help shed light on a number of cosmic mysteries, such as how black holes could have reached gargantuan sizes quickly after the Big Bang and how the universe got cleared of the murky fog that once filled the entire cosmos, the researchers said in the new study.
3. Supermassive black holes with masses millions to billions of times that of the sun are thought to lurk at the hearts of most, if not all, galaxies. Previous research suggested these giants release extraordinarily large amounts of light when they rip apart stars and devour matter, and likely are the driving force behind quasars, which are among the brightest objects in the universe. Astronomers can detect quasars from the farthest corners of the cosmos, making quasars among the most distant objects known. The farthest quasars are also the earliest known quasars—the more distant one is, the more time its light took to reach Earth.
4. Right after the Big Bang, the universe was a rapidly expanding hot soup of ions, or electrically charged particles. About 380,000 years later, these ions cooled and coalesced into neutral hydrogen gas. The universe stayed dark until gravity pulled matter together into the first stars. The intense ultraviolet light from this era caused this murky neutral hydrogen to get excited and ionize, or gain electric charge, and the gas has remained in that state since that time. Once the universe became reionized, light could travel freely through space.
Answer the question: What do supermassive black holes release while absorbing stars or devouring matter?

Black holes carry enormous amounts of energy in the form of light and are probably the driving force behind the quasars, which are among the brightest objects in the universe.
