Crossword-Solution: RESOLVABILITY 13 letters, 1 clue 🏆 scrabble score: 21

Finding that his potent instruments resolved into stars many nebulous patches in which no signs of such a structure had previously been discernible, he naturally concluded that "resolvability" was merely a question of distance and telescopic power.

While, just as we inferred that, according to circumstances, the extent to which aggregation has been carried must vary; so we find that, in fact, there are regular nebulæ of all degrees of resolvability, from those consisting of innumerable minute masses, to those in which their numbers are smaller and the sizes greater, and to those in which there are a few large bodies worthy to be called stars.

Whatever inference we may draw from the resolvability of some of the nebulæ, we may not draw this inference;--that they are more distant, and contain a larger array of systems and of worlds, in proportion as they are difficult to resolve.

But indeed the nebulæ themselves, and especially the most remote of the nebulæ, or at least those which most especially require the most powerful telescopes, offer far more decisive proofs that their resolvability or non-resolvability,--their apparent constitution as diffused and vaporous masses,--does not depend upon their distance.

Yet within this globular space we have collected upwards of six hundred stars of the seventh, eighth, ninth, and tenth magnitude, nearly three hundred nebulæ, and globular and other clusters _of all degrees of resolvability_, and smaller scattered stars of every inferior magnitude, from the tenth to such as by their magnitude and minuteness constitute irresolvable nebulosity, extending over tracts of many square degrees.
