Turbulência cósmica altera sinais pelo Universo

UNIVERSO Imagem: Fala Ciência/ AI

A luz de um quasar viajou 10 bilhões de anos-luz. No caminho, cruzou uma região turbulenta da Via Láctea. E algo estranho aconteceu.

O espaço entre as estrelas não é vazio. Gás e partículas distorcem ondas de rádio. Como o calor que embaralha o ar no asfalto.

Astrônomos analisaram quase 10 anos de dados do VLBA. Eles esperavam uma imagem borrada. Mas encontraram padrões incomuns na luz.

As distorções revelaram turbulência no espaço interestelar. Foi a primeira detecção direta desse fenômeno cósmico.

A descoberta ajuda a entender como a energia circula pela galáxia. E como novas estrelas podem surgir.

A turbulência também atrapalha imagens de buracos negros. Agora, cientistas querem remover essas distorções do espaço.
