Having said this, Saturn’s rings are currently only tilted to our line of sight, which makes them appear extremely thin and somewhat less impressive than when they are presented at a wider tilt angle.
In the days running up to opposition, the rings appear to brighten in what’s known as the Seeliger or opposition effect, dimming again in the days that follow.
The effect is caused by the myriad ring particles lining up with their shadows, effectively hiding them.
Around opposition, Saturn remains visible all night long.
As we are now on the latter side of the June solstice, from the Northern Hemisphere, the lengthening nights will help to keep Saturn centre-stage for many weeks to come.
