Perched on the edge of perception –
Six concentric rings of water, ice,
And dust rotate.
To the untrained eye you appear
Frozen in time.
An ancient halo of steadfast
But in between the sheets of rock
And air your certainty is
There’s a push and a pull.
And like a thread of
Floating on a rippled lake,
You find yourself entangled
On the knotted rope of this cosmic
Tug of War;
Finley balanced on a razor’s edge
Between the fiery embrace of home
And the chilly valediction of
And so, you fight against the push,
You rage against the pull;
Carelessly crashing into the
Pockmarked corpses of your siblings
In a vain attempt to stem the tide.
Until suddenly –
A flash of light
Causes the hackles on your stony flesh
And you find yourself unwillingly drawn
Into that milky, marbled orb.
A fatal, and unrequited attraction
As you fall like rain
Onto a planet that welcomes you
With open graves.
This science poem is inspired by recent research, which has found that Saturn is losing its iconic rings, as they are pulled into the planet by gravity.
Saturn is the sixth planet from our Sun and the most distant that can be seen from Earth by the naked eye. It is perhaps best known for its beautiful ring system, first observed by Galileo Galilei in 1610. This ring system is comprised of six main rings, each itself made up of thousands of tiny ringlets, with the largest of these rings measuring over 270,000 km, with a thickness of only 200 m! They are made up of floating chunks of ice, rocks, and dust, which collide constantly with one another.
These ring particles are caught in a balancing act between the pull of Saturn’s gravity (which wants to pull them into the planet) and their orbital velocity (which wants to hurl them into outer space). Tiny ring particles can also become electrically charged by UV light from the Sun, and when this happens, they also feel the pull of Saturn’s magnetic field, which curves inward toward the planet. This can cause the balance of forces on these tiny particles to change dramatically, causing the particles to be pulled into Saturn’s atmosphere as ‘ring rain’. This new research has estimated that Saturn’s rings will likely not exist in 100 million years’ time, whilst also indicating that they are unlikely to have been formed more than 100 million years ago. Given Saturn’s age of over 4 billion years old we are thus incredibly lucky to be living in a time where they can be observed. However, this temporary nature of planetary rings also means that we may just have missed out on seeing spectacular ring formations on other planets such as Jupiter and Neptune.
