![]() ![]() Lucid to Mir for a five month visit, increasing Mir's occupancy from 2 to 3. In late March 1996, Atlantis shuttled astronaut Shannon W. Sporting spindly appendages and solar panels, Mir resembles a whimsical flying insect hovering about 350 kilometers above New Zealand's South Island and the city of Nelson near Cook Strait. This dream-like image of Mir was recorded by astronauts as the Space Shuttle Atlantis approached the Russian space station prior to docking during the STS-76 mission. For location, Hesiodus and Pitatus are circled at the bottom of the picture. In the inset, the larger crater Pitatus is at the right. This picture of a first quarter Moon was recorded at 23:45 UT on February 22nd from Stuttgart, Germany. Seen in Hesiodus and other craters, the ray timing can be calculated based on the observer's location. Sunrise rays are short-lived and can be rewarding to spot for Moon enthusiasts with telescopes. Streaming through a gap in the eastern wall of 45 kilometer wide Hesiodus crater, the low-angle sunlight produces a long sunrise ray playing along the otherwise shadowed crater floor. But the picture's inset at the left highlights a more elusive lunar sunrise phenomenon. Of course, if viewed from the lunar surface near the terminator line, the Sun would be rising and still close to the lunar horizon. Stark shadows of mountains and crater walls stand out along the lunar terminator, or shadow line between night and day, in this telescopic image.

Stephan's Quintet lies within the boundaries of the high flying constellation Pegasus. Of course, including it would bring the four interacting galaxies back up to quintet status. Still, captured in this field above and to the left of Stephan's Quintet is another galaxy, NGC 7320C, that is also 300 million light-years distant. The mostly bluish galaxy, NGC 7320, is in the foreground about 40 million light-years distant, and isn't part of the interacting group. They also tend to have distorted loops and tails, grown under the influence of disruptive gravitational tides. The interacting galaxies, NGC 7319, 7318A, 7318B, and 7317 have a more dominant yellowish cast. The galaxies of the quintet are gathered near the center of the field, but really only four of the five are locked in a cosmic dance of repeated close encounters taking place some 300 million light-years away. The first identified compact galaxy group, Stephan's Quintet is featured in this remarkable image constructed with data drawn from Hubble Legacy Archive and the Subaru Telescope on the summit of Mauna Kea.
