Chang and Eng Bunker used as early as October 1829 to describe other conjoined twins. Decades later use of the standalone "Siamese twins"—which modern researchers see as outmoded, preferring "conjoined twins"—became widespread. Thus Chang and Eng have often been retrospectively referred to as the "original Siamese twins". Before the Bunkers' bodies were returned to North Carolina for burial (in 1917 they were moved to the cemetery at White Plains Baptist Church outside Mount Airy), doctors took photographs of the connecting tissue and hired sculptor John Casani to make a plaster cast of the twins. The Bunkers' fused livers are preserved in fluid and displayed
TWINS TWINS Two Wide-Angle Imaging Neutral-Atom Spectrometers (TWINS) are a pair of NASA instruments aboard two United States National Reconnaissance Office satellites in Molniya orbits. TWINS was designed to provide stereo images of the Earth's ring current. The first instrument, TWINS-1, was launched aboard USA-184 on 28 June 2006. TWINS-2 followed aboard USA-200 on March 13, 2008. Each instrument consists of an energetic neutral atom imager and a Lyman alpha detector. The ENA imager provides indirect remote sensing of the ring current ions, and the Lyman alpha detector gives a measure of the neutral hydrogen cloud about the Earth, known as
