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:
“After climbing a great hill, one only finds that there are many more hills to climb. I have taken a moment here to rest, to steal a view of the glorious vista that surrounds me, to look back on the distance I have come. But I can rest only for a moment, for with freedom comes responsibilities, and I dare not linger, for my long walk is not yet ended.”
—Nelson Mandela (b. 1918)
“I do believe that the outward and the inward life correspond; that if any should succeed to live a higher life, others would not know of it; that difference and distance are one. To set about living a true life is to go on a journey to a distant country, gradually to find ourselves surrounded by new scenes and men; and as long as the old are around me, I know that I am not in any true sense living a new or a better life.”
—Henry David Thoreau (1817–1862)
“Honor the spirits, but keep your distance from them.”
—Chinese proverb.
