Galáxia no Céu
A Nebulosa da Bolha (NGC 7635) tem cerca de 7 anos-luz de diâmetro e está localizada a 7.100 anos-luz da Terra, na constelação de Cassiopeia. Ela é inflada por uma estrela gigantesca, com 45 vezes a massa do Sol, que libera ventos estelares violentos viajando a mais de 6,4 milhões de quilômetros por hora. Esses ventos varrem o gás interestelar frio à frente como um limpa-neves cósmico, criando a borda quase perfeita da bolha.
