<br> Elliptical Galaxy NGC 4261 STSCI PR-92-27B <br> Wide Field/Planetary Camera <br> <br> HST Image of NGC 4261: A giant disk of cold gas and dust fuels a <br> possible black hole at the core of the galaxy. Estimated to be 300 <br> light-years across, the disk is tipped enough (about 60 degrees) to <br> provide astronomers with a clear view of the bright hub, which <br> presumably harbors the black hole. The dark, dusty disk represents a <br> cold outer region which extends inwards to an ultra-hot accretion disk <br> with a few hundred million miles from the suspected black hole. This <br> disk feeds matter into the black hole, where gravity compresses and <br> heats the material. Hot gas rushes from the vicinity of the black <br> hole's creating the radio jets. The jets are aligned perpendicular to <br> the disk, like an axel through a wheel. This provides strong <br> circumstantial evidence for the existence of black hole "central <br> engine" in NGC 4261. <br> . <br>
