Active Galaxies: where matter meets cosmic monsters
Imagem da galáxia ativa Centaurus A gerada a partir de três instrumentos que operam em distintos comprimentos de onda. A cor laranja corresponde à emissão no rádio, e a cor azul à emissão nos raios X. A faixa de poeira e estrelas característica desta galáxia é observável na luz visível. Esta imagem composta mostra um núcleo brilhante e poderosos jatos que resultam de interações muito energéticas entre o buraco negro supermassivo central e a matéria envolvente.
