Saturn’s glorious rings take center stage in a beautiful new photo by NASA’s Cassini spacecraft, which scientists dubbing it a “ring-bow.”
“Although the rings lack the many colors of the rainbow, they arc across the sky of Saturn,” NASA officials wrote in a photo description today (July 25). “From equatorial locations on the planet, they’d appear very thin since they would be seen edge-on. Closer to the poles, the rings would appear much wider; in some locations (for parts of Saturn’s year), they would even block the sun for part of each day.”
Though NASA released the image today, Cassini actually captured it on April 10, when the probe was about 680,000 miles (1.1 million kilometers) from Saturn’s cloud tops, NASA officials said. Each pixel is about 43 miles (69 km) wide, they added. [See more amazing photos of Saturn’s rings]
The $3.2 billion Cassini-Huygens mission — a joint effort of NASA, the European Space Agency and the Italian Space Agency — launched in October 1997 and arrived in Saturn orbit in July 2004.
The Cassini mothership carried a lander called Huygens, which landed on Saturn’s largest moon, Titan, in January 2005. Huygens ceased operating about 90 minutes after its touchdown, but Cassini kept right on studying Saturn, its iconic rings and many moons.
But that work will soon come to an end. Cassini is currently embarked on the Grand Finale phase of its long, accomplished mission — a series…
