Galileo points his telescope at Jupiter (1610)

posted Wednesday, 7 January 2015

Die itaque septima Januarii instantis anni millesimi sexcentesimi decimi, hoca sequentis noctis prima, cum coelestia sidera per Perspicillum spectarem, Juppiter se se obviam fecit, cumque admodum excellens mihi parassem instrumentum, (quod antea ob alterius Organi debilitatem minime contigerat ) tres illi adstare Stellulas, exiguas quidem, verumtamen clarissimas, cognovi; quae licet e numero inerrantium a me crederentur, nonnullam tamen intulerunt admirationem, eo quod secundum exactam lineam rectam, atque Eclipticae parallelam disposítae videbantur, ac caeteris magnitudtine paribus splendidiores: eratque illarum inter se, et ad Jovem talis constitutio; ex parte scilicet Orientali duae aderant Stellae, una vero Occasum versus.   On the seventh day of January in this present year 1610, at the first hour of night, when I was viewing the heavenly bodies with a telescope, Jupiter presented itself to me; and because I had prepared a very excellent instrument for myself I perceived (as I had not before, on account of the weakness of my previous instrument) that beside the planet there were three starlets, small indeed, but very bright. Though I believed them to be among the host of fixed stars, they aroused my curiosity somewhat by appearing to lie in an exact straight line parallel to the ecliptic, and by their being more splendid than others of their size. Their arrangement with respect to Jupiter and each other was the following: that is, there were two stars on the eastern side and one to the west.

Eximium praeterea, praeclarumque habemus argumentum pro scrupulo ab illis demendo, qui in Systemate Copernicano conversionem Planetarum circa Solem aequo animo ferentes, adeo perturbantur ab unius Lunae circa Terram latione, interea dum ambo annnum orbem circa Solem absolvunt, ut hanc universi constitutionem tamquam impossibilem evertendaia, esse arbitrentur; nunc enim nedum Planetam unum circa alium converlibilem habemus, dum ambo magnum circa Solem, perlustrant orbem, vertum quatuor circa Jovem, instar Lunae circa. Tellurem, sensus nobis vagantes offert Stellas, dum onmes simul cum Jove 12. annorum spaitio magnum circa Solem permeant orbem.   Here we have a fine and elegant argument for quieting the doubts of those who, while accepting with tranquil mind the revolutions of the planets about the sun in the Copernican system, are mightily disturbed to have the moon alone revolve about the earth and accompany it in an annual rotation about the sun. Some have believed that this structure of the universe should be rejected as impossible. But now we have not just one planet rotating about another while both run through a great orbit around the sun; our own eyes show us four stars which wander around Jupiter as does the moon around the earth, while all together trace out a grand revolution about the sun in the space of twelve years.

December 25th 1642 Julian calendar: Sir Isaac Newton is born. Jesus on the other hand was actually born in the summer. His birthday was moved to coincide with the traditional pagan holiday that celebrated the winter solstice with lit fires and slaughtered goats.
