A false-color image of the Cygnus Loop supernova remnant. The extreme ultraviolet (EUV) light seen in the image originates from gas that was heated to very high temperatures by a supernova explosion. The temperature of the gas is between 1 and 5 million degrees Celsius.
A false-color image of Vela supernova remnant. The EUV light seen in the image originates from gas that was heated to very high temperatures by a supernova explosion. The temperature of the gas is between 1 and 5 million degrees Celsius.
The first-quarter Moon (30 kbyte image). During the all-sky-survey portion of its mission, EUVE scanned the Moon. While not a natural source of EUV light, the Moon does reflect sunlight at these wavelengths, providing an indirect method of studying variations in our star. Direct observation of the Sun would burn out EUVE's detectors. This image was created by combining 17 observations at various wavelengths.
The full Moon (54 kbyte image). This image was taken with EUVE's Deep Survey telescope just after the lunar eclipse of 10 December 1992. Notice that the bright regions correlate well with the lunar highlands and the dark regions with the maria.
This is an image of the entire celestial sky, as it appears in the extreme ultraviolet. In addition to stellar objects, the Cygnus loop and Vela supernova remnants are visible. The image was created by combining EUVE scans of many small strips of the sky. These scans were taken during the all-sky-survey portion of the EUVE mission. The black strips are data gaps.
This image is an EUVE Deep Survey observation of the Hyades Star Cluster. The diagonal strip in the middle of the image represents data taken with a particular filter, whilae that in the corners is from another filter. At least eight other sources are seen and marked with probably identifications. Some stellar images have a tri-lobed appearance due to the highly curved focal surface of the grazing incidence Deep Survey telescope mirror. The faintest star (M 25 VA 41) is detected in the EUV at about 1 count per 1,000 seconds.
