~~The Brown Ghoul: vdB 141 | vdB 141 is a reflection nebula located in the constellation Cepheus.Sometimes referred to as the ghost nebula, its awkward name is its catalog number in Sidney van den Bergh’s catalog of reflection nebulae, published in 1966.Several stars are embedded in the nebula. Their light gives it a ghoulish brown color~~

Glorious Sirius looks like one bright star but is actually a binary system composed of 2 stars (Sirius A, the brighter & Sirius B, a faint white dwarf). Together, they glitter like a silver-blue diamond! Binary stars are too close to be distinguished from one another when observed from Earth and are hence mistaken for one. The two stars of a binary typically orbit about a common center of mass. Sirius is easy to see in the spring and winter skies.

NASA. The Mountains of Creation nebula (W5) from the Spitzer space telescope. The image, dubbed the Mountains of Creation by astronomers, reveals hotbeds of star formation similar to the iconic Pillars of Creation within the Eagle Nebula, photographed in 1995 by the Hubble Space Telescope.

Halo of the Cat’s Eye TheCat’s Eye Nebula(NGC 6543) is one of the best known planetary nebulaein the sky. Its hauntingsymmetriesare seen in the very central region ofthis tantalizing image, processed to reveal the enormous but extremely faint halo of gaseous material, about 6light-yearsacross, which surrounds the brighter, familiarplanetary nebula.
