Astronomers are investigating ... This was true of the black hole at the heart of SDSS1335+0728, a distant and unremarkable galaxy 300 million light-years away in the constellation of Virgo.

This was true of the black hole ... X-ray light. The first signs of activity appeared in late 2019, when the galaxy unexpectedly began shining brightly, attracting the attention of astronomers.

These stars also experience gravitational redshift, where the intense gravity near the black hole stretches the wavelength of light emitted ... objects, astronomers have detected streamers of gas ...

While QPEs are often linked to black holes absorbing material from nearby stars, no evidence suggests a recent stellar disruption near Ansky. This has led scientists to explore alternative ...

A team of astronomers ... black hole. Prior to this new finding, all the black holes that have been identified have also had a companion star—they are discovered due to their impact on light ...

Astronomers had never witnessed a black hole “wake up” in real time—until now. Researchers have spent the past few years watching a black hole re-awaken roughly 300 million light-years away ...

In December 2019, an ordinary galaxy 300 million light-years from us in the constellation Virgo suddenly woke up. After decades of inactivity, the black hole ... X-ray flares. Astronomers believe ...

This artist’s impression illustrates the mechanism that could be at the origin of the powerful bursts of X-ray light ... Now, astronomers are getting a close look at a black hole that is ...

Astronomers can instead look for galaxies without a tilted jet coming from its black hole. This idea is key to understanding where intelligence could potentially have emerged and matured in the ...

In a galaxy 300 million light ... for astronomers to observe a black hole’s behaviour in real time.” These QPEs have forced scientists to rethink what causes such flares.
