New research from the Hubble Space Telescope suggests that our galaxy's central black hole Sagittarius A* belches out jets of material as it swallows surrounding gas clouds.
that these two residual effects of the fading jet are currently the only visual evidence of it impacting molecular gas.
Alex Wagner, co-author and assistant professor at the University of Tsukuba, said:"The streams percolate out of the Milky Way's dense gas disk. The jet diverges from a pencil beam into tendrils, like that of an octopus."'s Fermi gas lobes, they create multiple expanding bubbles that extend as far as 500-light-years. This soap-bubble-like structure has been mapped by other telescopes in various wavelengths of light.

The white fan shows where the proposed jet would extend into the Milky Way.The astronomers also Cecil said that there are similarities between this structure and that at the center of the Milky Way."A bow shock bubble at the top of the NGC 1068 outflow coincides with the scale of the Fermi bubble start in the Milky Way," he added."NGC 1068 may be showing us what the Milky Way was doing during its major power surge several million years ago.
