Black hole light echoes are an extreme form of gravitational lensing. To measure the masses and spins of black holes, ...

Porphyrion was around during an earlier part ... The findings are reported in a new paper, ‘Black hole jets on the scale of the cosmic web’, published in the journal Nature.

Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, ...

An artist's illustration of the longest black hole jet system ever observed. Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light-years.

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision ...

A fresh analysis of decades-old X-ray black hole jet data has revealed bright, lumpy features with mysterious speed changes.
