NASA has warned that, Saturn is losing its
rings at the worst possible rate, and that
they’ll eventually disappear completely.
The rings are mostly made of water ice, and
are being sucked into the planet by gravity.
Saturn is the second-largest planet in our
Solar System, and it is iconic due to the
ring system of ice particles, that encircle
it.
But according to Nasa, these ring systems
are now breaking away at the maximum rate.
As Saturn’s gravity sucks the material inward.
And now scientists are warning that the rings
could disappear within just 100 million years.
– a very short time in space history.
Scientists estimate that this ‘ring rain’
drains, an amount of water products that could
fill an Olympic-sized swimming pool, from
Saturn’s rings in half an hour.
From this alone, the entire ring system will
be gone in 300million years.
But to add to this, the Cassini spacecraft
measured ring material, and detected falling
into Saturn’s equator, - and the rings have
less than 100 million years to live.
This is relatively short, compared to Saturn’s
age of over 4 billion years.
One of the big mysteries around Saturn is
whether the rings formed with the planet,
or if they came later.
New research suggests, the latter is correct,
indicating that, they’re unlikely to be
older, than 100 million years.
That’s because it would take that long for
the inner C-Ring to become what it is today,
when compared to the denser outer B-ring.
Saturn’s B ring is denser than the inner
C ring, a discrepancy that scientists can
use to calculate, how old the rings are That
means Saturn’s rings are already halfway
to their demise.
We are lucky to be around to see Saturn’s
ring system, which appears to be in the middle
of its lifetime,l.
However, if rings are temporary, perhaps we
just missed out on seeing giant ring systems
of Jupiter, Uranus and Neptune, which have
only thin ringlets today.
