A wide-angle CCD camera.The North America Nebula The North America Nebula (NGC 7000) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the emission nebula resembles that of the North American continent, especially along the southeast (NGC 7000) is a region of ionized i·on·ize tr. & intr.v. i·on·ized, i·on·iz·ing, i·on·iz·es To convert or be converted totally or partially into ions. i hydrogen in the constellation Cygnus. A lane of dark dust superimposed on the glowing hydrogen gives the appearance of the U.S. East Coast and the Gulf of Mexico Noun 1. Gulf of Mexico - an arm of the Atlantic to the south of the United States and to the east of Mexico Golfo de Mexico Atlantic, Atlantic Ocean - the 2nd largest ocean; separates North and South America on the west from Europe and Africa on the east . This is one of the first pictures made with a new camera designed for studies of Halley's comet by George Herbig and Burt Janes of the Lick Observatory in Santa Cruz, Calif. The camera combines the high light sensitivity of charge-coupled-device (CCD CCD in full charge-coupled device Semiconductor device in which the individual semiconductor components are connected so that the electrical charge at the output of one device provides the input to the next device. ) photosensors with a wide field of view (4' by 6.5[deg.]) that CCD cameras have heretofore lacked. The picture was taken by Rich Pogge. |
