Saturn's Crisscrossed Rings Hide Tiny Moon

It seems that on every occasion we have a look at a new photograph of Saturn via NASA?S Cassini challenge, there?S continually some thing specific. And often, there?S hidden gem.

Captured on Feb. 11, this observation, at first, doesn't make a whole lot of sense. We already know that Saturn sports hundreds of distinct rings, but they all occupy the same plane. How did Cassini see rings that are criss-crossed?

Actually, this remark most effective indicates one ring aircraft, however in the back of are the shadows of every ring being solid on Saturn?S upper ecosystem, developing the phantasm there are 2 units of rings.

At first glance, Saturn's rings seem like intersecting themselves in an impossible way. In truth, this view from NASA's Cassini spacecraft shows the jewelry in the front of the planet, upon which the shadow of the earrings is cast. And because rings like the A ring and Cassini Division, which seem within the foreground, aren't totally opaque, the disk of Saturn and people ring shadows may be seen directly via the rings themselves.

But while you digest the scene and work out which lines are rings and which are shadows, you’re probably overlooking tiny moon Pan, a 17 mile (or 28 kilometre) wide satellite occupying a gap in the rings (just below the middle of the photo).

Many of the gaps in Saturn?S earrings possess small moons whose gravity maintains those jewelry clean of particles as they orbit. Pan occupies the well-known Encke Gap, as an instance. Many other gaps, but, don?T seem to have moons, so their nature is a touch extra mysterious. Some theories on ring dynamics suggest a number of those gaps may have formed via resonances with Saturn?S large moons.

The Cassini assignment is a cooperative undertaking of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the assignment for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its onboard cameras had been designed, developed and assembled at JPL. The imaging operations middle is primarily based at the Space Science Institute in Boulder, Colorado.

Regardless of the way they were shaped, Cassini maintains to seize their beauty, continuously reaffirming Saturn as the jewel of the solar system.
