Artwork of section through the female bladder
Female bladder. Artwork showing a section through the female urinary system. The bladder is seen as a pink sac at centre. This is a hollow organ that holds urine. Two tubes (ureters) from upper image lead urine from the kidneys to the bladder. Yellow drops of urine are seen emerging from the trigone, the triangular space at the base of the bladder (lower centre). At the base of the bladder, the narrow urethra emerges, a tube that carries urine to the exterior opening. Just above the exterior opening, pink muscles of the urethral sphincter are seen. This muscle relaxes or contracts to control the flow of urine out of the bladder

Astronomy & the electromagnetic spectrum
Astronomy and the electromagnetic spectrum. The EM spectrum runs from gamma rays (left), via X-rays, ultraviolet, optical, and infrared, to radio waves (right). Some spectral bands (radio, IR, optical) can employ sea-level or mountain-top telescopes. Other bands (notably UV, gamma, X-ray) suffer from absorption of EM radiation by Earth's atmosphere. They use balloons, planes and satellites to take telescopes into the upper atmosphere or outer space. Powerful sources of EM radiation are active galaxies (top left) in the gamma and X-ray bands, star-forming regions in infrared (top centre), supernova remnants and the glow of radiation from the Big Bang (top right) in the radio band
