Astronomical avatar of the week: The Hourglass Nebula: This formation of gasses was created when a dying star gently ejected its outer layers forming a glowing region of ionized gas as seen in the photo. The remaining core is known as a white dwarf, seen in the center. Our sun will leave a similar corpse behind after expending its nuclear fuel. This nebula is located in the constellation Musca, the fly, visible only in the southern hemisphere.
