NGC 1275

NGC 1275I've just added Hubblecast 18 to the Star Viewer Map. Hubblecast 18 explains how the Hubble Space Telescope has solved a long-standing puzzle about the giant but delicate filaments around the active galaxy NGC 1275.

The central cluster galaxy of NGC 1275 contains a massive network of spectral line emitting filaments, which appear to be being dragged out by rising bubbles of relativistic plasma generated by the central active galactic nucleus. The amount of gas contained in a typical thread is round one million times the mass of our own Sun.
