Distance
Distance estimates to NGC 5128 established since the 1980s typically range between 3-5 Mpc. Classical Cepheids discovered in the heavily-obscured dust lane of NGC 5128 yield a distance between ~3-3.5 Mpc, depending on the nature of the extinction law adopted and other considerations. Mira variables and Type II Cepheids were also discovered in NGC 5128, the latter being rarely detected beyond local group. The distance to NGC 5128 established from several indicators such as Mira variables and planetary nebulae favour a more distant value of ~3.8 Mpc.

Famous quotes containing the word distance:
“Midway the lake we took on board two manly-looking middle-aged men.... I talked with one of them, telling him that I had come all this distance partly to see where the white pine, the Eastern stuff of which our houses are built, grew, but that on this and a previous excursion into another part of Maine I had found it a scarce tree; and I asked him where I must look for it. With a smile, he answered that he could hardly tell me.”
—Henry David Thoreau (1817–1862)
“From a distance the rushing of the torrent delights and uplifts us, but it rocks us in a flimsy boat, we are overwhelmed by despair. The same applies to danger.”
—Franz Grillparzer (1791–1872)
“Letters to absence can a voice impart,
And lend a tongue when distance gags the heart.”
—Horace Walpole (1717–1797)
