Saturn Images from 2011 to 2021 showing
the changing tilt over this time From 2011 to 2017 the ring faces have been opening up and in 2018 to 2022 they begin to close up again as Saturn commences to tilt back in the opposite direction. |

Since 2011 we have kept a record of the
changes in Saturn’s ring tilt. (Actually, the entire planet & rings are
varying their tilt/appearance as viewed from Earth!) 2011 represented the first year we felt
that the images were of sufficient resolution to warrant keeping records; it
should also be noted that some of the images chosen were near opposition when
the “Seeliger Effect” caused the rings to look brighter than in other
images…the degree of “openness” also influencing their brightness. This year image (2021, the last/bottom
image above) shows that the ring-tilt is quite similar to
what it was back in 2012/2013. (the 2nd & 3rd on
along at the top) |

This
animation shows Saturn’s ring angle between 2011 & 2022. The ring
brightening (or Seeliger Effect) is conspicuous in some of the animation
frames. |

In the 2 images below
we see some of Saturn’s moons around this planet: the animation shows them
moving along their orbital path over a specific period – clicking on that
image displays it at full size. |

In the following 4 images we see the
shadow of Saturn’s moon Iapetus traversing the face of this planet, the first
an animated sequence with the next 3 being single images capturing this
even…an IR filter image then a colour image and lastly an image using a red
filter. It is important to realise that Iapetus
is not one of the moons seen around Saturn in these images – it is way out to
the right-hand side with the Sun shining from the right to cause Iapetus
shadow to appear “behind” Iapetus and to the left of this moon. This image capturing Iapetus shadow
clearly is quite rare and a difficult achievement, as are subsequent images
of the moon itself or other moons transiting Saturn in earlier images further
down this page, or in the 2023 collection. |

The next 4 images reveal a bright spot (a
storm) high in Saturn’s Northern Hemisphere in single and animated displays. |

The 2nd (colour) image below shows
a little group of bright storm spots about half-way between the top edge of
Saturn’s rings and the North Pole, slightly to the left of the middle of the
disk. |

The image below and the next (animation)
show one of Saturn’s moons itself (Iapetus) making a transit of Saturn’s Northern Hemisphere, as opposed
to the shadow transits of this moon in image further up the page. Like those shadow transits these images
are difficult to capture, relying upon good seeing, a well-prepared scope and elements of luck! |
