Gravitational lensing helps astronomers find one of the most massive black holes yet discovered, a 30-billion solar mass monster at the heart of a remote galaxy.
Astronomers theorize supermassive black holes at the hearts of many if not all large galaxies could host thousands of large planets out to distances up to 10 light years.
Astronomers using X-ray, optical and infrared telescopes have spotted three galaxies – hosting three supermassive black holes – in the process of merging.
New computer simulations show tangled magnetic fields in jets streaming away from supermassive black holes may be creating powerful electric fields and currents accelerating particles to enormous energies
Observations by NASA’s Chandra X-ray Observatory of two five-billion-solar-mass black holes at the cores of two ancient ‘red nugget’ galaxies show they squelched star formation early on while consuming surrounding gas.
Many, if not all, large galaxies host supermassive black holes, including the Milky Way. A new study predicts such galaxies likely host more than one, far from the galactic core, the result of earlier mergers.
