The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

One of the most perplexing discoveries in modern astronomy has been finding supermassive black holes, some weighing billions ...

The black hole begins as a dark and stealthy object, but when a star passes too close it gets pulled in by the black hole’s gravity and is stretched, or, to use the technical term ...

While the supermassive black hole in J2345-0449 is estimated to be between 250 million and 1.4 billion solar masses (there is a big uncertainty because J2345-0449 lacks a central bulge, making the ...

As this material funnels into the black hole, it releases vast amounts of energy, which scientists believe may be responsible for creating quasars, some of the brightest objects known in the universe.

However, astronomers have long questioned whether long, powerful jets could be spotted in the distant universe because the black holes responsible for them behaved differently in the early universe ...

Astronomers have spied a monster radio jet in the distant universe that’s twice the width of the Milky Way galaxy.The ancient object formed when the universe was less than 10% of its current age ...

Consider how the sky would look if you could see it in radio waves. Instead of stars, you would see a vista of strange behemoths, many of them appearing larger than the sun and the moon in our sky.

Porphyrion, observed 6.3 billion ... "Interestingly, the quasar powering this massive radio jet does not have an extreme black hole mass compared to other quasars," Gloudemans said.

The researchers who found Porphyrion then used the Giant Metrewave Radio Telescope in India and the VM Keck Observatory in Hawaii to pinpoint the black hole jet’s location to a galaxy ten times more ...

Astronomers first became fascinated by the black hole of 1ES 1927+654 in 2018 when it flared with a major outburst seen in optical, ultraviolet and X-ray light.

The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass ...
