Contents of The Deep Field
The final images were released at a meeting of the American Astronomical Society in January 1996, and revealed a plethora of distant, faint galaxies. About 3,000 distinct galaxies could be identified in the images, with both irregular and spiral galaxies clearly visible, although some galaxies in the field are only a few pixels across. In all, the HDF is thought to contain fewer than twenty galactic foreground stars; by far the majority of objects in the field are distant galaxies.
There are about fifty blue point-like objects in the HDF. Many seem to be associated with nearby galaxies, which together form chains and arcs: these are likely to be regions of intense star formation. Others may be distant quasars. Astronomers initially ruled out the possibility that some of the point-like objects are white dwarfs, because they are too blue to be consistent with theories of white dwarf evolution prevalent at the time. However, more recent work has found that many white dwarfs become bluer as they age, lending support to the idea that the HDF might contain white dwarfs.

Famous quotes containing the words contents of the, contents of, contents, deep and/or field:
“Yet to speak of the whole world as metaphor
Is still to stick to the contents of the mind
And the desire to believe in a metaphor.
It is to stick to the nicer knowledge of
Belief, that what it believes in is not true.”
—Wallace Stevens (1879–1955)
“Conversation ... is like the table of contents of a dull book.... All the greatest subjects of human thought are proudly displayed in it. Listen to it for three minutes, and you ask yourself which is more striking, the emphasis of the speaker or his shocking ignorance.”
—Stendhal [Marie Henri Beyle] (1783–1842)
“If one reads a newspaper only for information, one does not learn the truth, not even the truth about the paper. The truth is that the newspaper is not a statement of contents but the contents themselves; and more than that, it is an instigator.”
—Karl Kraus (1874–1936)
“Affection, indulgence, and humor alike are powerless against the instinct of children to rebel. It is essential to their minds and their wills as exercise is to their bodies. If they have no reasons, they will invent them, like nations bound on war. It is hard to imagine families limp enough always to be at peace. Wherever there is character there will be conflict. The best that children and parents can hope for is that the wounds of their conflict may not be too deep or too lasting.”
—New York State Division of Youth Newsletter (20th century)
“And there, a field rat, startled, squealing bleeds,
His belly close to ground. I see the blade,
Blood-stained, continue cutting weeds and shade.”
—Jean Toomer (1894–1967)
