Page 263 - This news was to me like the coming upon a spring of water in a dry and thirsty land. Here at last presented itself the very order of work for which in an indefinite way I was looking — namely, to extend his novel methods of research upon the sun to the other heavenly bodies.
Page 267 - ... suggested by Sir William Herschel, out of which stars are elaborated by a process of subsidence and condensation. In such a primordial fluid, all the elements entering into the composition of the stars should be found. If these existed in these nebulae, the spectra of their light would be as crowded with bright lines as the stellar spectra are with dark lines.
Page 265 - The observations recorded in this paper seem to afford some proof that a similar unity of operation extends through the universe as far as light enables us to have cognizance of material objects. For we may infer that the stars, while differing, the one from the other, in the kinds of matter of which they consist, are all constructed upon the same plan as our sun, and are composed of matter identical, at least in part, with the materials of our system.
Page 263 - I soon became a little dissatisfied with the routine character of ordinary astronomical work, and in a vague way sought about in my mind for the possibility of research upon the heavens in a new direction or by new methods.
Page 590 - One-third of the whole nebulous contents of the heavens are congregated in a broad irregular patch, occupying about oneeighth of the whole surface of the sphere; chiefly (indeed almost entirely) situated in the northern hemisphere, and occupying the constellations Leo, Leo Minor, the body, tail, and hind legs of Ursa Major, the nose of the...
Page 267 - They may be gaseous nebulae, which by the loss of heat or the influence of other forces have become crowded with portions of matter in a more condensed and opaque condition. 6. If the observations of Lord...
Page 267 - M., can no longer be regarded as aggregations of suns after the order to which our own sun and the fixed stars belong. We have in these objects to do no longer with a special modification only of our own type of suns, but find ourselves in the presence of objects possessing a distinct and peculiar plan of structure.
Page 590 - Herschel as an element of whatever speculation a closer attention to this subject, and a more perfect classification of nebulous objects, may lead us to indulge in, that the most condensed portion, and what may fairly be regarded as the principal nucleus of the region of Virgo, is situated almost precisely in one pole of the Milky Way.
Page 333 - ... continued increase in absolute width in passing from center to limb, as well as direct observations with a radial slit, all point to a high level, small depth, and extreme tenuity for the absorbing layer. (4) A possible cause of the high radiating power of the emitting layer may be found in its increased temperature resulting from the transformation into heat of the mechanical energy set free by the loss of velocity in the opposing upward and downward currents. Mr. St. John is continuing the...
