Ômega Centauri NGC5139 WO66 FR Asi533mcpro 24L 120s g100 0c 0D 0B 48m 21.04.2025 L-Pro

Após algum tempo sem capturar esses objetos, que acho fascinantes, resolvi voltar a me dedicar um pouco mais a eles: os agrupamentos estelares globulares. Esté o maior e mais brilhante deles no céu noturno: Ômega Centauri (NGC5139). Visível a olho nu, relativamente próximo ao Cruzeiro do Sul, está localizado a cerca de 15.800 anos-luz de distância, na constelação de Centaurus. Contém mais de 10 milhões de estrelas.

 

After some time away from capturing these fascinating objects, I decided to return to them with renewed focus: globular star clusters. These are some of the oldest stellar systems in the universe. Here is the largest and brightest one in the night sky: Omega Centauri (NGC 5139). Visible to the naked eye and located relatively close to the Southern Cross, it lies about 15,800 light-years away in the constellation Centaurus. It contains over 10 million stars packed into a dense, spherical swarm.
