Es tracta d’una exposici\u00f3 itinerant que mostra els m\u00e8todes per a mesurar dist\u00e0ncies als cossos celests i com aquests m\u00e8todes s’han anat desenvolupant amb els anys segons les dist\u00e0ncies a mesurar.<\/p>\n

Alguns dels procediments emprats en el passat avui en dia s\u00f3n obsolets per manca de precisi\u00f3, d’altres s’han millorat amb nous instruments i s\u00f3n imprescindibles per arribar a mesurar dist\u00e0ncies cada cop m\u00e9s grans. I \u00e9s que els diferents m\u00e8todes que s’apliquen a les diferents dist\u00e0ncies no s\u00f3n independents entre ells. Per estimar la dist\u00e0ncia a la gal\u00e0xia m\u00e9s llunyana cal saber la que ens separa de gal\u00e0xies properes. Alhora aquestes dist\u00e0ncies properes no es podrien calcular sense saber abans a quina dist\u00e0ncia s\u00f3n les estrelles i quina dist\u00e0ncia ens separa del Sol. La mida de l’Univers es calcula comen\u00e7ant pel cossos que tenim m\u00e9s a prop i anant cada vegada m\u00e9s lluny, amb procediments successius i depenents.<\/p>\n

Tot i que l’exposici\u00f3 s’ha elaborat en motiu del tr\u00e0nsit de Venus del 5-6 de juny del 2012, \u00e9s una exposici\u00f3 atemporal.<\/p>\n
