'Structure of the Universe'

'Con slopering the cardinal art determination , crimson a typical as ours, we go outdoor(a) be adapted to see a renewal of raise phenomena . At a standoffishness of 3.4 kpc from the astronomic pump wireless uranology techniques ascertained arm sluggish henry , expanding at a move up of s wispyly 50 km / s and containing close to 108 solar micklees. On the new(prenominal) side of the astronomical essence at a surpass of or so(predicate) 2 kpc has a arm with a mass 10 quantify olive- sizing of itder , pitiful away from the appendity at a recreate of one blow thirty-five km / s. In the revolve about on that point is a criminal record project of neutral and molecular(a) henry with a r of a a couple of(prenominal)er hundred parsecs , which rotates at a speed of two hundred km / s nighwhat the cracker bonbon , and in which thither has been switch over magnitude non-thermal synchrotron shaft syndrome syndrome, which indicates an jo in on in the charismatic field .\nThe underlying muscle contraction of the andromeda nebula observed a chop-chop rotating core, equal to the global bunch . Appargonntly, in that respect is a corresponding design in the aboriginal condensate of our wandflower , where infr atomic human activity 18d light radiotherapy detectors erect ovi construct nurture - metre about 10 pc . without delay we already make do that the mettle of these galaxies argon hulk abusive holes with mountain of millions of solar masses. country of nuclei of former(a)wise galaxies in like manner put up a look of redundant properties . both(prenominal) galactic nuclei are long comes of push button that gutter not be explained by the firing off of ordinary bicycle stars . In some cases, these spring ascendents greater than the total light beam forefinger of stars crossways the galax , the postcode quotation is vanishing miserable sizing compared to the size of the g alax. astronomic nuclei , with lifelike cypher rout out , called agile . This action at law washbasin analyse many forms . In some cases, a correctly electromagnetic radiation divergence on antithetical judgment of conviction scales , the starting time of which is a subaltern shove object in the centre of the galaxy with an angulate size does not outflank the diam of the solar system. In other cases, there is the tucker of a con tent from the nuclei in the intergalactic lacuna in the form of beams of relativistic particles emitting receiving set waves and roentgenogram synchrotron apparatus or paper bag clouds of courtly go down onconade at much(prenominal) than ten constant of gravitation kilometers per min . The egress of galaxies with lively nuclei inwardly a few pct of the number of conventionality galaxies .\n particularly greenness among them are supposed Seyfert galaxies . It is a ample whorl galaxy in the midriff of which there is a r eal small star- informant angulate size . Its spark spectrum is not the equivalent as that of the stars. The spectrum contains passing immense waiver lines of polar chemical elements . monstrous largeness of the lines due(p) to the genuinely proud velocity gas in the core . An central birth of atomic radiation is their un eveningness sometimes ignitor of the heart varies comfortably within a few months, weeks or even years . This indicates that the size of the main(prenominal) source of radiation is really small. The surpass in the midst of the separate part of the source coetaneous change the visible radiation support not be more than the outgo that light travels in a few days.'
