... Bad Astronomy . ... Bitesize Astronomy . ... Have you ever looked at pictures of Saturn's rings and noticed what look like gaps in the rings? ... Gian Domenico Cassini discovered a large gap in Saturn's rings in 1675. Later, an astronomer named Encke discovered a smaller gap near the edge of the rings. ... It was found long ago that an orbit in the Cassini Division, as the large gap is named, has a period almost exactly one-half that of one of Saturn's moons named Mimas. ... 2008 Phil Plait. ...

... An Elliptical Ring Nebulosity Around Serpens/SVS 20: Circumbinary Disk or Outflow? ... Serpens SVS 20 is a binary pre-main sequence star, whose components are separated by 1.5 arcsec. ... Recent images of better spatial resolution show that this nebulosity is in fact a nebulous ring of elliptical shape, centered in the binary star, with two nearly symmetric extensions, as spiral-like arms. Possible explanations for this structure are a circumbinary disk or an outflow. ...

... The ring current (e.g., Frank, 1967) consists of geomagnetically trapped 10 - 200 keV ions (mainly H + , He + , and O + ) and electrons that drift azimuthally around the Earth at radial distances of about 2-7 Re (Earth radii), overlapping the radiation belt region. ... This index can be used to monitor the development of geomagnetic storm (see also geomagnetic activity ), as the main signature (actually definition) of the storm main phase is the build-up of an enhanced ring current. ...

M57 is another famous and often photographed object. It is also known as the Ring Nebula. ... Of course, they have nothing to do with planets but rather represent late stages in the evolution of low mass stars in which a double shell source (Hydrogen and Helium Burning) around a non-fusing Carbon core is driving the outer layes of the star away, thus revealing a hotter star (the central star of the Planetary nebula). ...

... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky. All these occurrences may be divided into three categories: one that occur in the near or far space, processes going on in the Earth atmosphere under the influence of cosmic factors and at last the occurrences connected with the Earth atmosphere. ...
