La gal\u00e0xia NGC 2997<\/h2>\n\n\n\n

NGC 2997 \u00e9s una gal\u00e0xia espiral, amb un disc lleugerament garsat, com passa amb el disc de la Via L\u00e0ctia. La pres\u00e8ncia de superc\u00famuls globulars d\u2019estrelles al centre \u00e9s una caracter\u00edstica que distingeix esta gal\u00e0xia de la nostra. Es troba a 30 millions d\u2019anys llum de nosaltres, i la vegem en la constel.laci\u00f3 austral de l\u2019Antlia (la M\u00e0quina Pneum\u00e0tica).<\/p>\n\n\n\n

Com \u00e9s el model 3D<\/h2>\n\n\n\n

Al model s\u2019aprecia la forma garsada del disc i els bra\u00e7os espirals amb nucs brillants de formaci\u00f3 estel\u00b7lar exagerats en relleu perqu\u00e8 puguen sentir-se. <\/p>\n\n\n\n

El centre de la gal\u00e0xia est\u00e0 representat per una esfera, ja que a les imatges veiem una bola lluminosa uniforme i resplendent. Hem deixat l\u2019esfera oberta a la part posterior de la gal\u00e0xia perqu\u00e8 pugam percebre les xicotetes protuber\u00e0ncies que representen els superc\u00famuls globulars que habiten esta regi\u00f3 i que nom\u00e9s podem vore canviant el contrast de la imatge. <\/p>\n\n\n\n

La xicoteta depressi\u00f3 del centre est\u00e0 col\u00b7locada per indicar la possible exist\u00e8ncia d\u2019un forat negre supermassiu amb la massa de milions de sols.<\/p>\n\n\n\n

Per a crear el model s\u2019ha utilitzat una imatge obtinguda a partir de dades d\u2019observacions amb filtres U, V, R, I i H alfa, que permeten detectar els procesos de formaci\u00f3 d\u2019estrelles.<\/p>\n\n\n\n
