The constellation of Orion is rich with impressive nebulas. Of the many interesting details that particularly draws the eye is Barnard’s Loop, the bright red circular filament arcing down from the middle. The bright orange star on the upper left is Betelgeuse, while the bright blue star on the lower right is Rigel. Other famous nebulas visible include the Witch Head Nebula, the Flame Nebula, and the comparatively small Horsehead Nebula. NASA-APOD, Stanislav Volskiy.

Saturn eclipsing the sun, with the Earth visible in the upper left section of Saturn's rings. In 2009, NASA's robotic Cassini spacecraft drifted in Saturn's shadow for about 12 hours and Cassini saw a view unlike any other. The rings light up so much that new rings were discovered. (NASA/APOD)
A nebula known as "the Spider" glows fluorescent green in an infrared image from NASA's Spitzer Space Telescope | Toward the right of center, against the black background of space, you can see a bright group of stars called "Stock 8." The light from this cluster carves out a bowl in the nearby dust clouds, seen in the image as green fluff. Along the sinuous tail in the center, and to the left, the groupings of red point sources clumped in the green are also young stars.
