On a clear night, these antelopes have 10x eyesight, which allows them to view Saturn's rings.
On a clear night, prong-horned antelope may possibly see Saturn's rings! According to Stan Lindstedt, an Arizona scientist, pronghorns are the finest endurance athletes in the world. They can keep up a speed of 40 miles per hour for almost an hour! This makes them capable of seeing objects as far away as 50 miles.
However, because they live in such large groups that include both males and females, their ability to see anything special is limited. Only mature males can be found alone outside of breeding season because females need protection while hunting and feeding. The female returns to join her partner once she has found enough food. During this time, he will not move from his post unless threatened or alarmed by some unusual noise or activity nearby. When she does return, it is usually with several small calves which indicate that she is able to find food and shelter for her family.
The scientific name for the pronghorn is Aplodontia rufa and it is found in North America. There are two subspecies: one lives in Mexico and parts of Central America, the other one is found in the United States from Texas to South Dakota. Scientists think that the ring system in Saturn's atmosphere might be responsible for the formation of hurricanes on Earth so it is likely that Saturn also has weather patterns like we do.
Saturn's rings are unlike any other planet's in our solar system. They are so large and dazzling that they were found as soon as humans began looking up at the night sky using telescopes. Galileo Galilei was the first person to use a telescope to observe the skies. In 1610 he saw moons around Jupiter and stars along the path taken by comets. He also saw rings around Saturn but they were too small to be seen with the unaided eye.
The discovery that all the giant planets have satellites makes seven, but only four of these bodies are visible to the naked eye. The largest satellite of Jupiter is Jupiter I. It is larger than Earth but less massive. This makes it difficult for astronomers to study because it passes across the face of its planet every 12 years or so.
Saturn's biggest moon, Titan, has a surface that is probably rich in organic chemicals. It has clouds and rains on this world, which has an atmosphere made mainly of nitrogen. There is some evidence that water may flow on this surface. Astronomers think that perhaps one day humans could travel there and live.
Unexpected discoveries are common when scientists look closer at our solar system. Many mysteries remain about the origins of the planets and their contents. But even after hundreds of discoveries have been made they are just beginning to understand how many interesting things are hidden in the darkness of space.
During excellent viewing spells, details in the rings can be seen with a tiny scope. The dark Cassini Division between the A and B rings is the most obvious. Its clarity is a great indicator of atmospheric stability and the optical quality of the telescope. The other major divisions within the rings are less distinct.
The colors of the rings are due to sunlight filtering through different amounts of dust suspended in the atmosphere. Red is more visible because it's absorbed by water vapor in the air, while blue is less affected. Dust in the atmosphere also blocks out light from stars behind it, so when observing from a dark site you need only look up to reveal the night sky!
Saturn's atmosphere is made up of clouds of gas and particles that are colorized by the sun. The cloud layers change with time and location on the planet. Layers high in the atmosphere tend to be redder than those closer down to the surface because they are filled with larger particles that reflect more light.
The image above was taken in 2010 with NASA's Cassini spacecraft. It shows portions of the giant planet's atmosphere as viewed from space. The photo was taken at a distance of approximately 930,000 miles (1.5 million kilometers).
