Des del cel nocturn de Prades<\/strong>, al Baix Camp<\/strong>, s\u2019ha detectat una nebulosa no catalogada<\/strong> fins ara, situada a la gal\u00e0xia del triangle M33<\/strong>, una de les m\u00e9s properes que coneixem. Aleix Roig<\/strong>, astr\u00f2graf del Parc Astron\u00f2mic de les Muntanyes de Prades<\/strong>, l\u2019ha descobert des del seu observatori Astrocat.<\/p>\n

La nova nebulosa s\u2019ha batejat com a \u201cRoig1 Prades Sky<\/strong>\u201d en record a l\u2019avi del seu descobridor, qui el va iniciar en el m\u00f3n de l\u2019astronomia, i al cel de Prades, el poble que estimen i des d\u2019on observen el cel. La troballa ha estat possible gr\u00e0cies a la qualitat del cel nocturn<\/strong> i a l\u2019esfor\u00e7 dels municipis de Muntanyes de Prades i Montsant<\/strong> en el canvi d\u2019enllumenat.<\/p>\n

L\u2019entorn es troba en la zona protegida de cel fosc m\u00e9s gran d\u2019Europa<\/strong> i t\u00e9 la certificaci\u00f3 internacional de Destinaci\u00f3 Tur\u00edstica Starlight<\/strong> des de l\u2019any 2021. L\u2019Ajuntament de Prades va comen\u00e7ar a fer el canvi d\u2019enllumenat a LED PC-ambre<\/strong> des del 2015 fruit de reunions amb els impulsors del Parc Astron\u00f2mic, Aleix Roig<\/strong> i Georgina Serven<\/strong>.<\/p>\n

Un registre in\u00e8dit<\/h2>\n

La gal\u00e0xia M33<\/strong> es pot observar amb prism\u00e0tics en cels nocturns foscos com els de Prades, per\u00f2 la nebulosa \u201cRoig1 Prades Sky<\/strong>\u201d, a 2,7 milions d\u2019anys llum<\/strong>, no s\u2019havia detectat fins ara. Aquesta gal\u00e0xia, ja estudiada des del segle XVII, \u00e9s de les m\u00e9s properes i que t\u00e9 una mida de 2,5 llunes plenes<\/strong> al cel.<\/p>\n

A trav\u00e9s d\u2019una cerca meticulosa amb planificaci\u00f3 a mesos vista i la utilitzaci\u00f3 de filtres de banda estreta<\/strong>, diferents dels que habitualment s\u2019utilitzen, ha estat possible captar la nebulosa que s\u2019estima que t\u00e9 una mida d\u2019uns 1.500 anys llum de di\u00e0metre. Ha calgut realitzar una imatge profunda de 153 hores de registre <\/strong>d\u2019imatges durant moltes nits.<\/p>\n

La nebulosa t\u00e9 una brillantor 10.000 vegades m\u00e9s d\u00e8bil <\/strong>que la gal\u00e0xia M33. Aquest \u00e9s un dels motius pels quals mai ning\u00fa l\u2019havia descobert abans. Un altre dels motius \u00e9s que els astr\u00f2noms professionals nom\u00e9s cobreixen petites \u00e0rees<\/strong> de la gal\u00e0xia M33 de forma habitual i solen emprar filtres RGB <\/strong>en lloc dels de banda estreta, emprats en aquest cas.
\nEl descobriment ha estat publicat per l\u2019American Astronomical Society <\/strong>en un article juntament amb la Judith Ard\u00e8vol<\/strong>, astrof\u00edsica per la Universitat de Barcelona i guia del Parc Astron\u00f2mic Muntanyes de Prades, i Ra\u00fal Infante<\/strong>, doctor en astrof\u00edsica del CEFCA (Arag\u00f3).<\/p>\n

Creaci\u00f3 d’un observatori cient\u00edfic<\/h2>\n

El Parc Astron\u00f2mic de les Muntanyes de Prades<\/strong> \u00e9s una realitat des de l\u2019any 2016 amb el suport de l\u2019Ajuntament de Prades amb la voluntat d\u2019apropar la passi\u00f3 per l\u2019astronomia<\/strong>, la protecci\u00f3 dels cels foscos<\/strong> i la recerca cient\u00edfica <\/strong>a la societat.<\/div>\n
