Astronomers Spot Unusual Jet from Supermassive Black Hole in PGC 43234

This artist’s impression shows a supermassive black hole consuming a star that has been torn apart by the black hole’s gravity; as a result of this ‘meal’ the black hole begins to launch a powerful jet that astronomers can detect with radio telescopes.

A group of scientists, led by Dr Sjoert van Velzen of Johns Hopkins University, has observed a new way for plasma to escape the gravitational pull of a supermassive black hole. This artist’s impression shows a supermassive black hole consuming a star that has been torn apart by the black hole’s gravity; as a result of this ‘meal’ the black hole begins to launch a powerful jet that astronomers can detect with radio telescopes.

Left: a ground-based view of the Milky Way’s central bulge; giant dust clouds block most of the starlight coming from the galactic center. The Hubble Space Telescope, however, peered through a region (marked by the arrow) called the Sagittarius Window, which offers a keyhole view into the galaxy’s hub. Upper right: this is a small section of Hubble’s view of the dense collection of stars crammed together in the galactic bulge. Lower right: a sample of 4 out of the 70 brightest white dwarfs spied by Hubble in the Milky Way Galaxy’s central bulge. The numbers in the inset images correspond to the stars’ location in the larger Hubble view. Image credit: NASA / ESA / A. Calamida & K. Sahu, STScI / SWEEPS Science Team / A. Fujii.
