Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually ...

The dense stellar remnant would, if confirmed, be the closest known object to any black hole, according to preliminary ...

The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight ...

Since 2018, we've seen 1ES 1927+654 generate jets in real time and found it may have a lone white dwarf orbiting near the ...

According to the calculations, the likely object was a white dwarf about 10 percent the mass of the Sun. It was moving about ...

Potentially habitable exoplanets are so incredibly common that astronomers have started to consider more unusual situations ...

"This tells us that objects like white dwarfs may be able to live very close to an event horizon for a relatively extended period of time." Using the XMM-Newton X-ray telescope, astronomers have ...

Scientists have observed X-rays emanating from a white dwarf orbiting a supermassive black hole in a galaxy near the Milky Way. The study notes the stability of the dwarf's orbit, despite its ...

The observations revealed features never before seen in real time around a supermassive black hole. Among them was the launch ...

In a recent study, an Italian astronomer has investigated the nature of a binary system known as HD 49798/RX J0648.0–4418.

It's the definition of "no pain, no gain." The rapid spin of this white dwarf, that is vampirically taking stellar matter away from a companion star, could be explained by its shrinking radius.
