The Southern Ring planetary nebula (360 Composite)

Some stars go out with a bang. This image shows the Southern Ring planetary nebula, the James Webb Space Telescope shows a dying star cloaked by dust and layers of light.

The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that this star is cloaked in dust.

Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away.

Webb will allow astronomers to dig into many more specifics about planetary nebulae like this one – clouds of gas and dust expelled by dying stars. Understanding which molecules are present, and where they lie throughout the shells of gas and dust will help researchers refine their knowledge of these objects.

This observation shows the Southern Ring Nebula almost face-on, but if we could rotate it to view it edge-on, its three-dimensional shape would more clearly look like two bowls placed together at the bottom, opening away from one another with a large hole at the center. In thousands of years, these delicate layers of gas and dust will dissipate into surrounding space.

ANATOMY OF THE KIDNEYS

The top of each kidney is opposite the 12th thoracic vertebra; the bottom is opposite the third lumbar vertebra. The right kidney is slightly lower than the left one. Each kidney weighs 113 to 170 g (4 to 6 oz), and each is about 11.4 cm (4 1 2 in) long, 5 to 7.5 cm (2 to 3 in) broad, and 2.5 cm (1 in) thick. The kidneys in the newborn are about three times as large in proportion to body weight as they are in the adult.

Each kidney is surrounded by adipose tissue and by the renal fascia, a fibrous membrane that helps hold the kidney in place. On the medial side of a kidney is an indentation called the hilus or hilum, at which the renal artery enters and the renal vein and ureter emerge. The microscopic nephrons are the structural and functional units of the kidney; each consists of a renal corpuscle and renal tubule with associated blood vessels. In frontal section, the kidney is composed of two areas of tissue and a medial cavity. The outer renal cortex is made of renal corpuscles and convoluted tubules. The renal medulla consists of 8 to 18 wedge-shaped areas called renal pyramids; they are made of loops of Henle and collecting tubules. Adjacent to the hilus is the renal pelvis, the expanded end of the ureter within the kidney. Urine formed in the nephrons is carried by a papillary duct to the tip (papilla) of a pyramid, which projects into a cuplike calyx, an extension of the renal pelvis.

During a meeting on June 6, 1876, at the Masonic Lodge in New York City, the 20 Shriners in attendance established the governing body of the fraternity, originally called the Imperial Grand Council, now known as the Imperial Council. Fourteen nobles were elected to serve 3-year terms on the Imperial Grand Council, with Walter Fleming, M.D., presiding as Grand Potentate. Happy
