Centaurus A - Distance

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:

    Egoism is the law of perspective as it applies to feelings, according to which what is closest to us appears to be large and weighty, while size and weight decrease with our distance from things.
    Friedrich Nietzsche (1844–1900)

    By sharing the information and observations with the caregiver, you have a chance to see your child through another pair of eyes. Because she has some distance and objectivity, a caregiver often sees things that a parent’s total involvement with her child doesn’t allow.
    Amy Laura Dombro (20th century)

    Like the water, the Walden ice, seen near at hand, has a green tint, but at a distance is beautifully blue, and you can easily tell it from the white ice of the river, or the merely greenish ice of some ponds, a quarter of a mile off.
    Henry David Thoreau (1817–1862)
