Cassini discovers a kinematic spiral ring around Saturn.
Since the time of the Voyager flybys of Saturn in 1980-1981, Saturn's eccentric F ring has been known to be accompanied on either side by faint strands of material. New Cassini observations show that these strands, initially interpreted as concentric ring segments, are in fact connected and form a single one-arm trailing spiral winding at least three times around Saturn. The spiral rotates arou...
متن کاملHorsing around on Saturn.
On the basis of simple statistical mechanical models, the prevailing view of the rings of Saturn is that they are unstable and must therefore have been formed rather recently. In this paper, we argue that the Saturn rings and inner moons are in much more stable orbits than previously thought and, therefore, that they likely formed together as part of the initial formation of the solar system. T...
متن کاملBlack Saturn with Dipole Ring
We present a new stationary, asymptotically flat solution of 5D EinsteinMaxwell gravity describing a Saturn-like black object: a rotating black hole surrounded by a rotating dipole black ring. The solution is generated by combining the vacuum black Saturn solution and the vacuum black ring solution with appropriately chosen parameters. Some basic properties of the solution are analyzed and the ...
متن کاملSeeing the Shadow of Rings around a “Super Saturn”
Astronomers think they have found a planet that has a giant set of rings around it, over 200 times larger than the rings around the planet Saturn. The planet is young enough that moons may be forming out of the material of the rings, and we are seeing the shadows of the rings here on Earth. We are now looking for other planets that have giant rings around them, and we may see rings in 2017 arou...
متن کاملRing around the chromatin
ells with shortening telomeres hit two successive barriers: they first stop dividing as they become senescent, and later undergo a cell death process termed crisis. Although crisis may, as suggested by others, be controlled by overall telomere length, and colleagues now blame the onset of senescence on a particular structure at the end of telomeres. The important structure is a single-stranded ...
