Holy moly: The Nancy Grace Roman Space Telescope construction is completed! That's fantastic news — much needed right now — and I am very much looking forward to when this beast launches. It has 100X the field of view of Hubble.

Worsening sky in Kuala Lumpur. High clouds and hazy.
Both group is still massive.
My estimation the total length of both group spans at least 30 times Earth's diameter.

Let's unravel the mystery of Saturn's polar hexagon.
A jet stream speeds around the pole at 320 km/h (200 mph). That’s common among planets, but what's not is that it oscillates up and down *very* stably. Each low point of this sine wave becomes a corner of a hexagon, when projected onto a sphere:
