Black holes don't have many identifying features. They come in one color (black) and one shape (spherical). The main difference between black holes is mass: some weigh about as much as a star like our ...

In a staggering find, scientists recently announced that the quasar closest to Earth is powered by two, not one, supermassive black holes. The quasar in question lives in a galaxy dubbed Markarian ...

And NASA just discovered that that particular quasar, 600 million light years away, is actually the result of a pair of black holes furiously orbiting one another, locked in a cosmic romance not ...

Astronomers have found that Markarian 231, the nearest galaxy to Earth that hosts a quasar, is powered by two central black holes furiously whirling about each other. Skip to content Introducing ...

Universe's most distant quasar found, powered by massive black hole. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2011 / 06 / 110629132527.htm ...

CAMBRIDGE, MASS. — For the first time, astronomers have detected starlight from distant galaxies that host extremely bright supermassive black holes called quasars. Data from the James Webb ...

A well accepted property of black holes is that they cannot sustain a magnetic field of their own. But observations of quasar Q0957+561 indicate that the object powering it does have a magnetic ...

Artist's impression of the bright core region of a quasar, an active galaxy. The supermassive black hole in the center is surrounded by a bright disk of gas and dust.

They sifted through over 17,000 quasar signatures to find this rare pair, sitting in the center of quasar SDSS 153636.22+044127.0 at a distance of about 4 billion light years from Earth.

The quasar that has just been found, named ULAS J1120+0641, is seen as it was only 770 million years after the Big Bang. It took 12.9 billion years for its light to reach us.

By comparison, the newly discovered quasar, called SDSS J0100+2802, is a giant among giants. The sheer size of the black hole has posed a new question about how something so massive was able to ...

The most distant quasar and the earliest known supermassive black hole have been discovered, shedding light on how massive galaxies formed in the early universe.
