ikenbot: Launching Into History On June 18, 1983, a young physicist from California took her seat aboard the space shuttle and launched into history. On that date, Sally Ride became the first American woman in space as a mission specialist on STS-7. In this image, Ride monitors control panels from the pilot’s chair on the flight deck.

ikenbot: Thackeray’s Globules These are larger dust bunnies than you will find under your bed. Situated in rich star fields and glowing hydrogen gas, these opaque clouds of interstellar dust and gas are so large they might be able to form stars. Their home is known as IC 2944, a bright stellar nursery located about 5,900 light years away toward the constellation of Centaurus.

ikenbot: Moon, Venus, & The Sun “The Moon and Venus displayed very similar phases yesterday (23 May) almost looking like twins, one heading for the Sun, the other having just performed a remarkable transit wich resulted in the annular eclipse 2 days ago. The Moon (30’) is still 2 arc minutes smaller than the Sun (32’). The sizes of the 3 bodies are correct but of course not their relative positions. Everything is shot in daylight so I have enhanced the contrast for the Moon and Venus.” — Peter Rosén
