NGC5189 Sw200p CC Asi533mcpro g100 55L 180s -10c 16D 18.05.2025 2h45m LUlt+Lpro

Nebulosa planetária NGC5189. Uma nebulosa com formato fascinante! Ela lembra um S retorcido, um formato peculiar que provavelmente é resultado da interação entre estrela que está no fim da vida uma companheira invisível, ou seja, uma estrela binária. À medida que a estrela central da nebulosa expulsa suas camadas externas, o campo gravitacional da companheira influencia o fluxo do gás, criando essas formas simétricas e curvas.

 

Planetary Nebula NGC 5189. A nebula with a fascinating shape! It resembles a twisted "S" — a peculiar structure likely caused by the interaction between a dying star and an invisible companion, meaning a binary star system. As the central star of the nebula expels its outer layers, the gravitational pull of the companion influences the gas flow, creating these curved and symmetrical forms.
