Helix Nebula SHO
The Helix Nebula, also known as NGC 7293, is a planetary nebula located in the Aquarius constellation. Its appearance resembles that of a cosmic helix, with layers of gas and dust expelled by a dying star at its center. This captivating structure results from the shedding of outer layers by a low-mass star, illuminated by its residual light.
