Quasars are so bright that they can be seen at vast distances across the universe; the most distant known quasar is seen as it appeared 13.13 billion years ago.

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Astronomers have discovered a quasar that remained hidden for over the years is the brightest ever, powered by the fastest growing black hole ever discovered that eats a sun every day.

The quasar, as bright as 500 trillion suns, has evaded astronomers for over 40 years because of its incredible luminosity ...

Astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind, but also the most luminous object ever observed. Quasars are the bright cores of distant ...

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding supermassive black hole.

Enter NRAO 530, a bright quasar located roughly 7.5 billion light-years away. According to a global team of scientists, it is the most distant object that the Event Horizon has imaged thus far.

The universe’s brightest object is a quasar in a distant galaxy that’s powered by the fastest-growing black hole ever recorded, according to a new study.

An image of a bright quasar that has been gravitationally lensed by the galaxy that appears faintly in the foreground.

Astronomers discovered a quasar, which is the "brightest of its kind" and the "most luminous object ever observed," using the European Southern Observatory's (ESO) Very Large Telescope (VLT), a ...

Eventually, the two quasars will combine to form a single, super-bright quasar at the heart of the newly formed monster galaxy.

The blindingly bright quasar, fueled by what Zakamska calls a "monster" black hole at the center of the galactic swirl, is a rare "extremely red" quasar, about 11.5 billion years old and one of the ...
