Primal Space

On the other side of the planet, around the South Pole, we find a similar phenomenon, except this time there are seven cyclones in a hexagon shape.

Just one of these cyclones is bigger than the United States in diameter.

In enhanced natural light, these vortices are beautiful.

We don't know how permanent these features are.

We've only discovered their existence since Juno arrived.

If anything, we would expect them to merge, but they seem to be enduring.

and nature certainly does like to throw us some curveballs from time to time.

As Voyager 2 flew by Neptune in 1989, we got very lucky.

At just that moment in Neptune's existence, it was experiencing a massive storm that stretched out for 13,000 kilometers.

Scientists thought they had just discovered a storm comparable to Jupiter's Great Red Spot, perhaps a permanent feature that had always been with Neptune.

As such, they named it Neptune's Great Dark Spot.

But when Hubble was launched and pointed at Neptune, the spot had completely disappeared.

Since then, Neptune has had other dark spots come and go, although perhaps not as big as the one Voyager saw.

All in all, it seems that Neptune spends about half its time with a dark spot.

The rest of the time, these storms may continue on as less powerful cyclones, before finding renewed strength depending on Neptune's weather conditions.

Number three, Jupiter's Great Red Spot.

It may surprise you to find out that Jupiter's red spot only made it to number three on this list.

Although you should be aware that this storm is certainly no pushover, having existed since Galileo first spotted it back in 1665.

During modern day observations, this storm was, at its maximum, the equivalent of three Earths across.

Although it is smaller today than it ever has been,
